Fish-and-Summer Kanji

𮬆 is a rare Japanese fish kanji recorded as “abalone” in an Edo-period dictionary published in 1717 and as “fugu” (pufferfish) in an 1815 text. A proposed explanation treats its fish-plus-summer shape as a distorted form of 鰒, another fish character. A sushi reference from 2026 also uses the glyph for wakashi (young yellowtail), though other character references distinguish that as the two-character spelling 魚夏; check the source's context to choose a reading.
