【English Name】Otouto

"Otouto" is a common Japanese word meaning "younger brother," but a usage as a technical term in the sushi industry could not be confirmed from the primary sources referenced this time.

The five sources provided were all Wikipedia articles concerning films, anime, commercial facilities, actors, and manga, and contained no information related to sushi or seafood. In source 2 (Koi☆Cent), "otouto" is used as the name of an anime character; in source 3 (Kawasaki Azalea), as the name of a mechanical-clock character; and in source 4 (Kameyama Shinobu), as a term indicating a sibling relationship—but none of these are related to sushi.

To accurately write this entry, re-investigation of appropriate materials demonstrating the usage of "otouto" as a sushi term is required.
