From the viewpoint in 'Zoku Zoku Bimigushin' (Delicacy Quest, third series) written by Kenjiro KINOSHITA in 1940, he said 200 pieces of Nigiri-zushi were made from two sho of rice, and that serving of Nigiri-zushi in pairs started after the war, a theory that Nigiri-zushi was cut into two pieces because it was too big is also unreasonable.
また、昭和15年の木下謙次郎「続々美味求真」に2升で200個握るとされていること、2個づけが戦後始まっていることを考えても、大きかったので2つに分けたと言う説には無理がある。
