As first reported by Eater London, the restaurant announced its permanent closure via a Facebook post on 5 October.
It said: "We are sad to announce that Sake no Hana will close its doors permanently from today.
"We have really enjoyed being a part of London’s exciting and innovative restaurant scene for the past 10 years. Our team at Sake no Hana continue to work in our sister restaurants Hakkasan Mayfair, Hakkasan Hanway Place, Yauatcha Soho and Yauatcha City.
"We would like to take this chance to say thank you to everyone who made Sake no Hana the restaurant it is, from our talented chefs to our team who ran the restaurant front of house and behind the scenes. We would also like to thank everyone who came into the restaurant."
Sake no Hana opened in 2008, and was previously owned jointly by restaurateur Jamie Barber and Evening Standard owner Evgeny Lebedev before being sold to Hakkasan in 2011.
The restaurant's closure comes after the US-centric Tao Group Hospitality acquired Hakkasan Group earlier this year.
In a statement, Hakkasan said: "Having opened in St James’ in 2008, Sake no Hana was best known for bringing together Hakkasan’s efficient and intuitive service style with a carefully selected menu, to deliver a Japanese restaurant experience of the highest quality.
"Sake no Hana would like to thank all of its guests for their continued support over the years."
