The origin of the world's sushi boom is this man!! His name is Hanaya Yobei!! The time is the Edo period of the Bunsei era. Although it was a popular sushi among the common people, it was called pressed sushi'' and familiar sushi,'' and was looked down upon and derided as ``waste'' in restaurants. At that time, a man appeared who wanted to take over the world with sushi. The unconventional sushi invented by that man, Yobei, is Edomae-style “nigiri sushi”!!
