AHJIKAN Co. Ltd. of Hiroshima City, who sells food ingredients for sushi, explains the appearance of barazushi (scattered sushi), one of specialities in Okayama, went back to an order issued by Mitsumasa IKEDA, the lord of Okayama Domain in Bizen Province, who encouraged people to live a modest and frugal life and often prohibited extravagant lifestyles, that restricted their daily meals to the one rice bowl with one side dish and one soup.
寿司の食品素材を販売する広島市の株式会社あじかんによれば、質素倹約を奨励し、庶民の奢侈をたびたび禁じた備前国岡山藩藩主の池田光政が汁物以外に副食を一品に制限する「一汁一菜令」を布告したことが、岡山名物のばらずしが生まれた背景となっていると説明している。
