What is "Nikkun Roll"? What do you think that? Just meat? No. This is the rice ball, japanese call "onigiri". "Nikkun Roll" is the rice ball wrapped in meat. Japanese calls meat "Niku". The origin of the name is the food mixed with "Niku" and "Rock'n Roll". Perhaps the shopkeeper likes "Rock'n Roll", we think. "Nikkun Roll" is 290Yen, cheap. If you have a time and a plan going to "Shimokita-zawa", please try to eat.
