Yosuke Imada is the owner of the gigantic sushi restaurant Kuybei in Tokyo. It was his father that originally founded the venerable, five-floor establishment in 1936. For more than 30 years, Mr. Imada has expanded Kyubei beyond Ginza - while maintaining its reputation as a veritable Japanese institution.
He has turned Kyubei into a $30 million enterprise with a total of seven restaurants, including several at some of the most prestigious hotels in Tokyo and Osaka, a thriving world-wide catering business, even a department store take-home sushi shop, all without losing the reputation for quality and service for which the restaurant is widely praised.
I found this picture of him on Flickr, and he looks like a really friendly sushi chef in addition to a hard working business man. We would like for him to come and open a place in Oslo. We promise to come!

Three days ago, he was here in Seoul, Korea.
Westin Chosun Hotel, one of major five star hotels in Seoul, Korea, re-opened its Japanese restarant ‘Sushi Cho’ on November 4, and a chef from Kyubei, Mr. Matsumoto Mizuho, has been dispatched to, and will stay at, Sushi Cho for the next three years, as a part of business alliance.
This culinary event follows the introduction of Pierre Gagnaire a Seoul, which opened at Lotte Hotel last month.
For the first two days of opening, Nov. 4 and Nov. 5, Mr. Imada Yousuke served sushi to the guests.
The restaurant has two “live sushi” rooms, one accommodating up to four guests and the other up to fourteen people.
I reserved one of the live sushi rooms and I was exclusively served by chef Imada san thorughout the dinner for three hours.
What an honor that was.
Mr. Imada is a charismatic, yet very friendly, thoughtful and down-to-earth person.
He is truly the maestro!
