How This Team of All-Female Chefs Is Leading a Culinary Revolution in Japan

The revered art of kaiseki has long been a man’s world. The chefs at Tsurutokame want to change that.

By Jeremy Rapanich 24/10/2019

It’s a few hours before Tsurutokame opens for the night, and the scene in the back of the house is intense. Seven chefs swarm the kaiseki restaurant in Tokyo’s upscale Ginza neighbourhood, gliding around their tight quarters like choreographed dancers, performing their prep work in near silence. With a steely determination, Yubako Kamohara leads the brigade, moving deftly among her staff. One moment she’s correcting a cook’s technique for slicing bonito sashimi; the next she’s helping another cook arrange the intricate fish-shaped ceramics that will contain the night’s first course. The constant furrow of her brow is a reminder that she’s carrying the heavy weight of expectation.

The pressure Kamohara is feeling goes well beyond creating an impeccable dinner service tonight. The 34-year-old head chef knows that scrutiny is following her every move because in Japan, the kitchens of kaiseki restaurants have long been a man’s world—until she came along. Kamohara is the first to lead an all-female team of kaiseki cooks, and she’s ready to show her country that she’s not the only woman up to the task.



Predictably, Kamohara’s path to Tsurutokame was neither short nor easy. It all started with Osamu Mikuni, a Tokyo chef who, along with his wife, Harumi, owns 11 restaurants in the Japanese capital. He had witnessed his industry’s overt sexism throughout his 52-year career and realized that change wasn’t coming anytime soon—unless he did something.

“I’ve seen a lot of talented women, but because the culinary world is very male-dominated, it’s hard for them to climb up the ladder and become front and centre,” Osamu says. “I started this restaurant as a mission to help achieve gender equality in the restaurant world.”



To make the biggest possible impact, he wanted women to take on kaiseki, the country’s most prestigious and artful cuisine. Kaiseki is more than just dinner: It’s the expression of time and nature through the flavour and representation of food. It’s a centuries-old art form where the order of courses tells a story about the seasons, where even the plates used to serve the food are carefully considered. “The visuality and performance struck me as very similar to Japanese theatre,” says Eric Rath, a University of Kansas history professor who focuses on Japan’s food culture. Kaiseki is a forerunner to modern tasting menus in fine-dining restaurants around the world, and it’s been especially hard for female chefs to break in. “There is a long tradition of women serving as chefs and owners of restaurants, but they’re not at the level of kaiseki,” says Rath, “but the patriarchal nature of the restaurant trade makes it difficult for them to advance in that career.”

The idea came easily to Osamu, but the talent took longer to find. He searched for years for a leader strong enough to handle the pressure of a kaiseki kitchen, until he, at last, discovered Kamohara working in one of his restaurants at a Tokyo department store in 2015. “She was very aggressive and positive, and her work style was energetic,” says Harumi. The only catch? She wasn’t a chef—not even a cook. But it didn’t matter to the Mikunis. “We were impressed. We felt this was the girl we wanted to lead the restaurant. We could teach her to cook.”



So the couple set about convincing Kamohara, who had also worked as a nutritionist, to leave her retail career behind and train for Tsurutokame. They quickly realized, however, that the traditional Japanese way of training kaiseki chefs—an excruciatingly long process that takes years—would not do. “It can take three years before a cook gets to grill fish,” Kamohara says. At that rate, the restaurant wouldn’t open for a decade. So the Mikunis put the scale of their business to good use, hiring the women and training them simultaneously by having them take shifts at all their restaurants for one year. The formula would have Tsurutokame opening its doors in December 2016.

Still, despite being the Mikunis’ chosen one, Kamohara says those early days weren’t all smooth sailing. In fact, it was practically a comedy of errors, this restaurant full of women where almost nothing seemed to go right. Rookie mistakes happened all the time, from jumbling the order of courses (a cardinal sin in kaiseki) to forgetting to send out a dish altogether. And then there was the stigma—and salacious rumours—of a legendary male chef grooming so many women for one restaurant. But eventually, things fell into place. “I could see Yubako growing mentally [and] physically, and her management skills improved,” says Harumi. “They were becoming one team—seven people looking in the same direction.”



That teamwork grew out of Osamu’s demanding yet holistic approach to guiding his staff. Because kaiseki is an art, he trained his artists beyond the mere craft of cooking. At the Mikunis’ headquarters across town, the couple regularly hosts the restaurant team for lessons in Japanese literature and ancient tea ceremonies. They sometimes gather around a piano to sing traditional songs, with a few J-pop hits sprinkled in for good measure.

Osamu says it’s all part of his approach; he pulls out a piece of paper and writes in Japanese three characters that represent “heart,” “technique” and “body.” “It comes down to balancing those three aspects in order to have a balanced soul,” he says. “Technique anyone can get—you just have to train. Heart comes with the lessons and tea ceremonies to develop their inner core. And you need to maintain your body as well. All over the world, chefs in Michelin restaurants have committed suicide, and that has to do, I believe, with overworking people.”



Kamohara, meanwhile, has her own aspirations for the restaurant to help achieve gender equality by pushing against another societal constraint. “Traditionally, women in Japan work until they’re about 25 and then quit to be full-time moms,” says Rath. “And then later when their children are old enough, they go back, but only work part-time.” Kamohara wants Tsurutokame to be a place where women can move quickly through the levels of kaiseki, training faster in the years before those life events throw a wrench into their careers—and offering a chance for them to rejoin the workforce once they’re ready to come back.

As Kamohara quietly oversees the pre-dinner prep, she acknowledges she’s still working to develop her voice as a chef. “I need to face directly toward the ingredients,” she says, sounding a lot like her poetic mentor. “For example, bonito fish comes in every day right now because it’s high season, but every day it’s different, so I need to use a different kind of cooking.”



Tonight, the bonito is perfect for sashimi, which Kamohara serves with shiso, ginger, chives and garlic marinated in soy sauce. At each of the 14 seats at Tsurutokame’s counter, diners young and old are perched around the chefs, watching as the team executes a traditional eight-course menu. Kamohara and crew maintain the steady focus of their pre-service prep, but with two of the groups in attendance celebrating birthdays, the kitchen can’t help but get swept up in the convivial atmosphere. As the night closes out, they all join in to belt out a song they rehearsed at choir practice the day before. Kamohara allows herself to smile for the first time all night, and the diners break into applause. But it’s not the song that’s getting the accolades; it’s the food—and the women behind it.

A Michael Jordan Logoman Patch Card Just Sold for a Record $2.9 Million at Auction

The one-of-one piece is now the most expensive Jordan card to ever cross the auction block.

By Tori Latham 06/06/2024

Michael Jordan was a record-breaking athlete—and the legendary hooper is continuing to set records more than two decades after his (final) retirement from the game.

A one-of-one signed and game-used Jordan Logoman patch card just sold for an eye-popping USD$2.9 million, making it the most expensive Jordan card ever sold at auction. The 2003 card was part of the Goldin 100 auction, where it received 38 bids before finally hammering down for that multimillion-dollar total.

Goldin

The rare card, which was included in an Upper Deck Ultimate Collection, is the very first signed Logoman patch card with Jordan in a Chicago Bulls jersey. The patch itself is from Jordan’s peak with the Bulls, a team he led to six NBA championships. The bold blue autograph on the bottom of the card, meanwhile, was graded PSA 10. It’s unclear where the card was before 2022, when it was submitted to PSA for grading, and this is the first time it’s been offered in a public auction. Altogether, it’s considered to be the most exclusive Jordan autographed Logoman card in the world.

While Jordan is perhaps most well known for what he’s done on the court, the baller is no stranger to making waves on the auction block, too. Earlier this year, a set of his NBA Finals–worn sneakers achieved a bonkers $8 million during a Sotheby’s auction. Even then, that’s not the most someone has paid for Jordan memorabilia: In 2022, the athlete’s game-worn “Last Dance” Finals jersey hammered down for a whopping USD$10.1 million.

The recent card sale may not match those numbers, but almost USD$3 million is still a hefty sum to pay for a relatively compact item. And the card easily swept the rest of the Goldin 100 auction. The highest following lot was a Kobe Bryant jersey that the late Los Angeles Laker wore during a 2013 game. That piece of sports history ended up going home with someone for USD$1.2 million.

As the richest basketball player ever, with a net worth of $3.5 billion as of a year ago, Jordan himself is far outearning his card’s value. But it’s unlikely that he would have ever made that much money without paving the sort of path that makes his memorabilia so desirable when it hits the auction block.

You Can Now Buy and Sell Luxury Watches and Jewellery on eBay’s Consignment Service

The e-tailer is making inroads on being a major marketplace for high-end goods.

By Tori Latham 06/06/2024

eBay is continuing to make inroads into the luxury industry.

The website on Tuesday expanded its consignment service to include high-end watches, jewellery, and footwear. Among the brands being accepted by the program are Christian Louboutin, Jimmy Choo, and Louis Vuitton for shoes; Chanel, David Yurman, and Neil Lane for jewellery; and Breguet, Girard-Perregaux, and Jaeger-LeCoultre for timepieces.

eBay’s consignment program debuted at the end of last year for handbags, and it added apparel to the mix in March. The service is meant to make selling high-end goods easier for those looking to offload their pieces, and more trustworthy for those hoping to buy them. The e-tailer has partnered with the company Linda’s Stuff to streamline the process: A seller fills out a simple intake form, then receives a prepaid and insured shipping label to send in their items. eBay and Linda’s Stuff photograph, price, and list the item, with the seller receiving a commission based on the final sale price. If a piece sells for $5,000 or more, for example, the seller receives 80 percent.

Since launching its consignment service, eBay has seen that items listed that way are selling for more than similar pieces listed on the website in the more traditional way. In just one example, a small quilted Chanel 19 flap bag consigned in December hurdled past the average sales price for the same purses sold on eBay by 45 percent.

In recent years, eBay has been training its efforts on making high-end, pre-owned items easier to sell and buy on its platform. It has implemented programs like Certified by Brand and Authenticity Guarantee to ensure that users feel confident when buying and selling luxury items on the website. And those sorts of used and refurbished items now compose 40 percent of eBay’s gross merchandise volume.

While it may seem a bit strange to sell your luxury items on eBay rather than a designated site like the RealReal, the e-tailer might be breaking out as the next big luxury marketplace, especially when it comes to pre-owned pieces.

Audemars Piguet Just Dropped a Bevy of New Watches—Including a Mini Royal Oak

From the new Royal Oak Mini to skeletonised 37 mm versions and a wild asymmetrical reissue, AP just slayed the spring watch season.

By Nick Scott, Paige Reddinger, Allen Farmelo 06/06/2024

Audemars Piguet isn’t resting on its laurels and that’s likely just how former longtime CEO, François-Henri Bennhamias, intended. The colourful head honcho left his post at the helm this past December, but he certainly left his mark by taking the brand to USD$2.7 billion in sales by 2023 before handing over the reins to newly minted CEO, Ilaria Resta, who was hired from global perfumery company, Firmenich. (Resta is the latest female addition to AP’s top brass following the appointment of Ginny Wright, who came from L’Oreal, as the CEO of North America.)

Given the lead time of R&D in watchmaking, the latest watches are certainly the mark of Bennhamias’s direction, and the watches are anything but wallflowers. You have wildly innovative new materials like a Royal Oak prototype proposed in Chroma Gold—a new technique blending white gold, rose gold, and yellow gold into a camouflage pattern—and a funky new “Crystal Sand” finish on the Royal Oak Frosted Gold Selfwinding 34 mm model. Meanwhile, Code 11.59 gets decked in an extraordinarily challenging arrangement of sapphires and diamonds, and the latest [Re]Master02 comes in a funky 1960s tv-shaped case with beveled sapphire crystal glass.

Here’s a look at how Audemars Piguet is flexing its craftsmanship muscles with these daring new timepieces.

Audemars Piguet

At 23 mm across, these are not the smallest Royal Oaks ever produced: a 20mm iteration was launched in 1997, alongside a 44mm Royal Oak Grande Complication, to celebrate the model’s 25th anniversary. They’re also not the sparkliest Royal Oaks: any number of abundantly gem-set models are all vying for that crown.

But the frosted gold trio before you are definitely amongst the most attention-grabbing Royal Oaks to date, residing as they do in the intersection of two Goldilocks zones: they’re well suited to slender-wristed wearers, but not so small that they invoke outmoded notions of femininity; and they’re mischievously sparkly, but packing only carefully measured flamboyance.

Audemars Piguet

Built from 18 carat yellow, white or pink frosted gold, the new pieces’ shimmering diamond-dust effect contrasts beautifully with the polished bevels. The case, bezel and bracelet have been created using a Florentine jewelry technique first applied to a Royal Oak in 2016, and again in 2018 with the help of Carolina Bucci. The frosting involves hand-hammering the metal using a diamond-tipped tool, and the effect is uniquely elegant and understated.

The dials—like that on Gérald Genta’s original steel game-changer—are uncluttered bar the petite tapisserie pattern. Unlike Genta’s original (a major counter-offensive salvo from the mechanical watches camp during the quartz crises) the beating heart for this trio is calibre 2730, a quartz movement with a seven-year battery life and easy-to-use deactivation mode.

Audemars Piguet

The smallest selfwinding Royal Oaks ever made remain Calibre 2062, a 29mm piece – created by former head of Audemars Piguet’s design office Jacqueline Dimier – which retained the codes of Genta’s original model created in 1976, and the gem-set derivative released shortly afterwards.

“These mini creations pay tribute not only to Audemars Piguet’s long tradition of miniature and jewellery watches, but also to the women who have left their mark on the history of the brand, including Jacqueline Dimier to whom we owe the first Royal Oak for women, and Carolina Bucci, the mastermind behind the Frosted Gold finish,” said Ilaria Resta Audemars Piguet’s Chief Executive Officer, in a statement.

Audemars Piguet

Sébastian Vivas—the maker’s Heritage and Museum Director—added that the three pieces “demonstrate the extraordinary plasticity of the Royal Oak collection, which transcends decades, gender, trends and dimensions.”

Size: 27 mm
Material: white, yellow and rose gold
Price: $51,700

Audemars Piguet

AP’s frosted gold Royal Oaks have been a hit for the brand since it debuted as a collaboration with Italian jeweler, Carolina Bucci in 2016. There have been several versions, including one with a mirrored dial, and now the nouveau classic is sporting a “Crystal Sand” finish.

Audemars Piguet

The 34 mm model’s dial offers a magnified and dramatized interpretation of the hammered case and surface of the bracelet. Made from embossed ruthenium crystal, the dial is then adorned with a stamping die via electroforming, a process that forms or grows metal parts onto a model. The color is achieved through a galvanic bath of both rhodium and gold coating to accentuate its 3D form.

Audemars Piguet

Size: 34 mm
Material: frosted gold
Price: $93,250

Audemars Piguet

Since 2010, Audemars Piguet’s Openworked Royal Oak models have been offered in sizes ranging between 39 mm (e.g., reference 15305) and 41 mm (e.g., reference 15407). Something about skeletonizing watches seems to cause many brands to reach for its larger cases: Perhaps it’s the larger dial for skeletonizing, or perhaps it’s a tendency to assume that men who like big watches will also prefer openworked dials. To be honest, I’ve long shared the latter assumption, though I’ve never had much reason to examine it before now.

Audemars Piguet often challenges our assumptions (consider the Spider Man Royal Oak, for example), and this new Openworked Double Balance Wheel Royal Oak at 37 mm in white or rose gold disregards assumptions about gender and watches while also underlining the small watch trend for men.

Audemars Piguet

Thirty-seven mm is pretty much the perfect “unisex” size. Many brands (for example, Grand Seiko, Lange, Rolex, Zentih) offer 37 mm watches that serve as a bridge between their men’s and women’s collections, and sometimes these brands will point that out. However, in its typical avant garde manner, Audemars Piguet is way ahead of this shifting norm—especially when compared to its counterparts in the Horological Holy Trinity, Patek Philippe and Vacheron Constantin, both of which offer 37 mm watches steered more obviously toward men or women with gem setting, or the lack thereof. By offering the Openworked Royal Oak at 37 mm, Audemars Piguet cleverly sidesteps that old-school his/hers conundrum.

Audemars Piguet

This watch is going to resonate with men who are continuing to lean toward smaller watches, and it’s going to resonate with women who are looking for a larger and more daring timepiece that won’t overpower (or simply overhang) their wrists. And this Royal Oak does all that gender bending by simply shrinking its skeletonized watch. In this regard alone, I think it’s a brilliant offering—and I’m not a big fan of openworked dials.

The dual balance wheel mechanism of caliber 3132 helps stabilize the balance staff in its ruby mount, which improves precision.
Audemars Piguet

With all that said, what’s really driving this watch’s avant garde nature is the movement, known as caliber 3132. The dual balance wheel is a unique approach to minimizing the tilt of the balance staff (the axil on which the balance wheel oscillates). When the balance wheel swings back and forth (like a pendulum), there is a tendency, due to inertia, for it to slightly tilt within its ruby mount. When the balance staff tilts (however slightly) gravity has its way with it, causing timing discrepancies in different positions (known as positional variance). By adding a second balance wheel (not just a second spring, as found in some movements), Audemars Piguet has added stabilizing mass to the mechanism, as well as a counter-force that further stabilizes the balance staff as it changes direction. Theoretically, this reduces tilt of the balance staff and reduces positional variance.

It also looks very cool, and you’ll get a good view from both the front and the back of this watch.

Size: 37 mm
Material: pink and white gold
Price: $147,300

Audemars Piguet

If you’d told me a few years ago that brutalism—a minimalist, institutional architecture style of the mid-20th century rendered with massive concrete slabs—was going to be a catchphrase of watch design by 2024, I’d have declared you an iconoclastic crackpot. But, you’d have been right.

Audemars Piguet has picked up on the recent nostalgia for that strangely appealing architectural style. Reaching into their catalog from the 1960s, when brutalism was peaking globally, they’ve found a very cool watch to recreate—or, as AP insists, to “[RE]Master.” Audemars Piguet has borrowed the term from the recording arts: Remastering is generally a slight modernizing of a recording for current markets, so the analogy holds here, as this watch slightly modernizes vintage model.

Audemars Piguet

Crafted from Audemars Piguet’s proprietary sand gold, the case will shift between white and pink gold hues, depending on ambient lighting. Using the trusted time-only only caliber 7129, this auto-winding mechanical movement is on display through a circular window in the caseback.

Audemars Piguet

Sébastian Vivas, AP’s Heritage and Museum Director, states that “Between 1959 and 1963, Audemars Piguet created more than 30 asymmetrical models, most of which were produced in less than 10 pieces. [RE]Master02 is a fantastic opportunity to revive this forgotten golden age.”

Audemars Piguet

Despite the wildly brutalist case, it may be the dial that steals the show here. Created using a dark blue PVD treatment over beautifully brushed surfaces, the 12 individually crafted dial segments cleverly help time telling without relying on applied markers. These dial segments are separated by galvanized sand gold partitions, and each segment sits on miniscule legs attached to a brass dial plate beneath. All of this geometric precision is accentuated by the beveled sapphire crystal.

Size: 41 mm
Material: sand gold
Price: $70,900(limited to 250 pieces)

Audemars Piguet

The Code 11.59 is getting all dolled up this year in a splash of gem-set models. Two 38 mm iterations come in either 18-karat pink gold or white gold set with 533 brilliant-cut diamonds and colored sapphires.

Audemars Piguet

What is notable here is the pixelated-looking setting. The pink-gold version comes with an array of navy, baby blue and yellow sapphires on the dial, while the white-gold version comes in pink and purple sapphires. Both look as though the colors were shaken in a glass and poured onto the dial so that the pattern is haphazardly arranged. It’s a fun take on a gem-set dial, one which we can’t recall seeing before and is, no doubt, extraordinarily difficult to arrange to achieve the right balance of hues. Each piece is set with the three-hand selfwinding caliber 5909.

Audemars Piguet
Audemars Piguet

One of the coolest pieces in the new lineup is just a prototype for now, but it offers a glimpse of what’s to come in the future. Chroma Gold is a patented innovation blending yellow gold, white gold, and rose gold via Spark Plasma Sintering technology. Each gold variation is melted before droplets are atomized into powders. They are then combined in their respective pattern in a circular graphite mold which is then sintered via an electrical current. It is a first for the watch industry.

Audemars Piguet

Even in jewellery it is notoriously difficult to work with multiple types of metal in one piece due to the variations in consistency and that’s without trying to blend them together. The only time we have seen the blending of two different types of gold before is in American jeweler Adam Neeley’s proprietary SpectraGold, which is currently pending a patent. AP’s Chroma Gold follows the debut of a similar method with ceramic that debuted in a prototype earlier this year allowing the company to blend various hues of the material. Camo isn’t for everyone, but the multi-hued gold version certainly makes a compelling case for the machismo pattern. On the right hands it will be irresistibly cool.

Watch of the Week: IWC Ceralume Pilot’s Chronograph

The concept watch hints at the future of IWC’s proprietary luminous ceramic technology.

By Josh Bozin 31/05/2024

Did you catch Lewis Hamilton rocking a new IWC Schaffhausen timepiece at the Monaco Grand Prix over the weekend? We did too, and as curious watch fanatics, we couldn’t help but speculate on what exactly this stark-white timepiece could be. A new iteration of the 2022 Pilot’s Watch Chronograph TOP GUN “Lake Tahoe” edition, perhaps?

Sort of.

Earlier this week, IWC took to Instagram to reveal what its experimental engineering division, XPL, has been working on over the last few years. Introducing the new IWC Ceralume Pilot’s Chronograph—a ceramic watch, albeit a prototype, that completely glows in the dark, from case to dial to strap!

IWC

Such wizardry is thanks to a proprietary luminous ceramic technology that IWC calls “Ceralume.” This technical feat has allowed IWC watchmakers to produce their very first fully luminous ceramic watch. Building on its 40-year journey as true pioneers of engineering ceramic material within watches—ceramic is notoriously difficult to work with, you see—IWC is no stranger to such technical feats.

Thanks to the homogeneous mixing of ceramic powders with high-grade Super-LumiNova pigments, IWC has fashioned a luminous material that acts like a battery for storing light energy. Utilising the new Ceralume technology, this fully luminous concept Pilot’s Chronograph emits a bright blueish light that lasts more than 24 hours.

“With the first fully luminous ceramic case rings, we underscore our role as a pioneer and innovator in ceramic watches. The development of Ceralume took several years. The main challenges we faced were producing watch cases with maximum homogeneity and meeting our exacting quality standards,” says Dr. Lorenz Brunner, Department Manager Research & Innovation at IWC Schaffhausen.

“To achieve these goals, we engineered a ground-breaking new manufacturing process – tailored to the unique combination of ceramic powders and Super-LumiNova pigments.”

If we’re to get extra technical, the ceramic material absorbs light energy from sunlight (or artificial light), stores it temporarily, and then emits the absorbed energy as visible light—the luminous “glow” that you see below. According to IWC, this cycle is infinite and will never cause the material to age or diminish its light storage capacity.

IWC

Developed completely in-house by IWC and its Experimental Engineering Division (XPL), the patent-pending Ceralume technology will undoubtedly form the foundation of future developments and releases, with a broader commercial release imminent.
