Stephen Lancaster now runs Sézanne after Daniel Calvert left the Four Seasons Hotel Tokyo at Marunouchi restaurant on March 31, 2026. Michelin took the restaurant's previous three-star listing offline following Calvert's departure, and inspectors are evaluating Lancaster's kitchen ahead of the autumn 2026 guide, according to the South China Morning Post's reporting on Michelin Japan's response. The Tokyo restaurant, opened in July 2021, now appears on the guide's platform with a new listing while Lancaster's work is assessed.
For diners who build Tokyo trips around the three-star circuit, that change lands before the next printed or digital update cycle. For cooks, it puts a sharper question on the bench: when the maker leaves, how much of the restaurant remains legible to Michelin? Lancaster inherits the room where Calvert built a rapid ascent, but he also inherits the task of proving what Sézanne becomes under his hands.
What Michelin Said After Calvert Left
Michelin Japan told the South China Morning Post that "following significant changes at Sézanne in spring 2026, the restaurant's previous listing on the Michelin Guide website was taken offline."1 The guide team also said, in the same reported response, that the restaurant has reopened with a new team and is being evaluated by inspectors.
That is the operative fact for anyone holding a reservation: Lancaster's Sézanne is no longer carrying the three-star listing Calvert earned. Michelin has not published, in the supplied reporting, a named inspector's note, a dish-by-dish account, or a technical explanation of what changed on the plate. The public record is narrower. Calvert departed on March 31, 2026. Lancaster replaced him. Michelin removed the old listing after spring 2026 changes and put the restaurant back on the platform as a new listing under evaluation.
The stars matter because Calvert accumulated them quickly. The restaurant opened in July 2021. Calvert received his first star within six months, a second star a year later, and three-star status in late 2024. In 2024, Sézanne ranked No. 1 on Asia's 50 Best Restaurants list. In 2025, it ranked No. 7 on the World's 50 Best Restaurants list. Those are separate systems, with separate voters and methods, but together they made Calvert one of the names international diners placed at the top of Tokyo planning sheets.
Michelin's move also sits beside its own previously published explanations, as cited in the source article. A 2016 Michelin Guide article said star ratings remain unaffected when a head chef leaves midyear and another chef arrives. A 2025 Michelin Guide answer said stars are awarded to restaurants, not chefs, and that a restaurant can keep stars if the cooking standard remains. The current case does not prove a universal policy change. It does show that Michelin Japan is treating Lancaster's Sézanne as a restaurant requiring fresh inspection.
What Calvert Built in Four Years
Calvert was Sézanne's opening chef. That detail carries weight because the first years of a restaurant set its working grammar: the way the pass calls for plates, the way a sauce station holds heat, the way a pastry section times the last course against the room, the way suppliers learn what the chef will reject. The source material does not give the menu ratios, the knife work, the stock schedule, or the fermentation hours behind Calvert's Sézanne. It gives the public record of the results: first star inside six months, second star a year later, three stars in late 2024.
Four years is a short time in a kitchen's life. It is long enough, though, for a chef to build a room's expectations and for diners to attach a name to a sequence of service. Calvert launched Sézanne in July 2021 inside the Four Seasons Hotel Tokyo at Marunouchi, a hotel setting that places the restaurant within a travel corridor as much as a local dining map. Marunouchi brings international visitors, business diners, and collectors who often book meals as carefully as flights. Calvert's tenure converted that address into a ranking fixture.
The timeline under Calvert reads like compressed apprenticeship for the restaurant itself. Six months to one star. Another year to two. Late 2024 to three. Asia's 50 Best Restaurants placed Sézanne at No. 1 in 2024; the World's 50 Best Restaurants placed it at No. 7 in 2025. Those positions did not belong to Calvert alone, because no service reaches that level through one pair of hands. Yet the listed chef shapes the method, sets the tolerances, corrects the station, and decides what leaves the pass.
That is why the removal of the stars after Calvert's exit has become more than a bookkeeping issue. Michelin may award stars to restaurants, but a restaurant's cooking standard lives through people. Calvert wrote the discipline into the team. The sous chefs enforced it. The pastry chef, commis, reservation staff, wine team, and room managers carried it through the service. When Calvert left and Lancaster took the pass, inspectors have to taste what remains, not what the restaurant once was.
Lancaster's Record Before Sézanne
Lancaster now inherits the bench that Calvert built. The source article identifies him as the new head chef and places his previous work in Singapore, where he led Saint Pierre to two-Michelin-star status. It also reports that his former restaurant, Poise, now closed, earned a Michelin star within its first year in 2022. That gives Lancaster his own Michelin record before Tokyo, not as a caretaker but as a chef whose kitchens have already been inspected and rated.
Lancaster's task at Sézanne is different from opening Poise or leading Saint Pierre. He is not entering a blank room. He is entering a restaurant whose name is still attached to Calvert's rapid rise, to a No. 1 Asia ranking in 2024, and to a No. 7 world ranking in 2025. Every returning diner will bring memory to the table, even if Lancaster wants to cook forward. Every inspector will be tasting his current work while knowing the former status has been removed.
The supplied reporting says Lancaster is reshaping the menu, but it does not provide dish names or technique. That absence should be respected. Until the restaurant or Michelin puts more detail into the public record, the craft question remains open: what does Lancaster keep, what does he cut, and where does he make the method his own? A new head chef can preserve the architecture of a menu while changing the pressure points. He can alter a sauce base, shorten a garnish list, change the pacing of a tasting menu, or move authority across stations. None of those specifics have been reported here, so none should be invented.
What can be said is that Lancaster arrives with time on the tools in Michelin kitchens and with direct experience of inspection pressure. Saint Pierre reached two-Michelin-star status under his leadership. Poise earned a star in its first year in 2022. At Sézanne, those credentials are not a substitute for inspection. They are the starting point for a new file.
What the Shift Means for Diners Holding Reservations
For diners, the practical shift is simple and awkward: a booking at Sézanne no longer carries the three-star designation that may have prompted the booking. The restaurant remains in the Four Seasons Hotel Tokyo at Marunouchi. Lancaster is the head chef. Michelin inspectors are evaluating his reopened restaurant ahead of the autumn 2026 guide update. Those are the facts a traveler can act on without guessing at the inspectors' eventual decision.
For collectors of restaurant experiences, the case creates a timing problem. Some diners book for the plaque, some for the chef, some for the room, and some for the chance to taste a kitchen during transition. If the purpose of a Tokyo itinerary is to eat only at current three-star restaurants, Sézanne no longer fits that brief for now. If the purpose is to watch Lancaster run a high-level kitchen under inspection pressure before the guide settles its judgment, the reservation has a different kind of value.
The hotel location matters here. A restaurant inside the Four Seasons Hotel Tokyo at Marunouchi is easier for international travelers to understand logistically than a harder-to-find independent address, but the location does not answer the central question. Michelin is not reassessing the lobby. Inspectors are reassessing Lancaster's cooking. The pass, not the postcode, is where the status will be won back or withheld.
There is also a difference between rankings and stars that seasoned diners already know but this case makes visible. Asia's 50 Best Restaurants and the World's 50 Best Restaurants recognized Calvert's Sézanne in 2024 and 2025. Michelin's current listing status has changed before the autumn 2026 update. A restaurant can hold ranking prestige in memory and lose star designation in the guide's current platform. The diner has to decide which signal matters for the trip at hand.
What Lancaster Has to Prove
The better question is not whether Sézanne is worth booking in the abstract. It is what kind of booking it now is. Under Calvert, it was a three-star restaurant with a documented ascent: July 2021 opening, one star within six months, second star a year later, three stars in late 2024, No. 1 in Asia's 50 Best Restaurants in 2024, No. 7 in the World's 50 Best Restaurants in 2025. Under Lancaster, it is a restaurant with a new head chef whose past kitchens include two-Michelin-star Saint Pierre and one-star Poise, now under Michelin evaluation in Tokyo.
That changes the posture of the diner. A Calvert-era booking looked backward and forward at once, toward a chef in command of a restaurant that had already been confirmed by Michelin. A Lancaster-era booking, at least before the autumn 2026 update, asks the diner to taste a transition. That can be a reason to go, if you follow makers rather than trophies. It can also be a reason to wait, if the itinerary depends on current guide status.
The people to watch now are Lancaster and the unnamed team around him: the sous chefs holding the pass when he steps away, the pastry section finishing the last plates, the room staff translating the new menu to guests who remember Calvert's version, and the Michelin inspectors returning with fresh notebooks. Calvert's Sézanne has already entered the record. Lancaster's Sézanne is still being written service by service.
Autumn 2026 will give the next public marker. Until then, the useful act is not to treat the missing stars as an ending, but as a change in authorship. Sézanne still occupies the Marunouchi room where Calvert built the climb; Lancaster now has to prove, plate by plate, what the restaurant becomes without him.
