"Tengen hikki" (established in the Meiji period) described that sushi stuffed with rice and tofugara (leftover after making tofu) (okara - bean curd residue) was eaten with soy sauce mixed with wasabi paste, and also that 'it was really gechoku (low price).'
『天言筆記』（明治成立）には飯や豆腐ガラ（オカラ）などを詰めてワサビ醤油で食べるとあり、「はなはだ下直（低価格）」ともある。
