In the Kansai region, from the Edo period, sashimi came to be known by other names including 'tsukurimi' and 'otsukuri,' which both consist of the verb 'tsukuru' (literally, to make), since this verb also has the meaning of 'to prepare food', which caused the expression '-tsukuri' to refer to the way of slicing fish.
関西では江戸時代以降、「作り身」「お造り」などというようになったが、これは「作る」という動詞に調理するという意味があるため、魚の切り方を「-作り」という表現で示すようになったことによる。
