Mr. Sato is a unique sushi chef who combines the blessings of the island country with local mountain food.

He was born in 1969 in Niigata. He is the second generation of Ryuzushi, which has lasted for more than 50 years in Minami-uonuma. After graduating high school, he moved to Tokyo and trained there, then in Nagaoka City, Niigata Prefecture. He took over the restaurant at 28 and built a fish purchase route that does not pass through the market, aiming to provide "the world's most cost-effective sushi." On the occasion of the restaurant renovation in July 2021, it became a counter sushi restaurant. His sushi, which uses wild vegetables and local produce of Minami-uonuma, attracts the attention of food connoisseurs from all over the country.
