Tancho’s koi is on sale for ¥1,400 ($1.25) per pound, and the restaurant serves Japanese kai fish, a specialty.
“It’s a very special dish for me, and I’m really happy about it,” Tanchomitsu says.
“The koi’s flavor and the koi are not too high in calories, but the taste is very good.”
Tancho, who also runs a sushi restaurant in Tokyo called Shukan Kiki, says he also gets requests from tourists from around the world to come and try the kai, which is one of his favorite dishes.
He has a personal connection with the Japanese kui, and hopes to eventually open a restaurant in Japan.
