It is understood that the Albemarle Street venture has been trading as Sushi Amamoto London since the beginning of the month.
Amamoto’s Sushi Amamoto restaurant opened in the Taiwanese capital, Taipei, in 2015 and currently holds two Michelin stars.
The existing leadership team at the London site — head chef Jongho Park and general manager Manson Au — remain in place, having managed the restaurant since its inception in 2022.
Taku received a Michelin star four months after opening and retained it in this year’s guide.
Watanabe is understood to have left the business towards the end of last year.
Prices are comparable, with lunch at £180 for 17 courses and dinner at £380 for 22 courses.
Sushi Amamoto London is Amamoto’s first venture outside Taiwan.
The restaurant will serve Edomae-style sushi, treating each piece as a complete dish rather than a simple bite. His cooking and presentation exemplify balance, temperature, texture and restraint.
The approach mirrors that in Taipei, but the restaurant will respond to its London context by following the natural rhythm of Britain’s seasons and offering local ingredients at their best.
The restaurant is operated by brothers Geoff and Lucas Leong. Their family heritage in Japanese cuisine in London began with their father, who opened Chinatown’s first Japanese restaurant in the early 1990s, followed by Koi in Kensington Palace Gate in 1997.
