proposed

anchorage at the thing with a nose attached to it

Proponent: 榊原正文

The reading refers the name to the cape.

Corrected for grammar the reading would run etu-ko-an-tomari 'anchorage at the nose'. The inlet is one bay short of the Yūnai River and some way from Cape Raiden, so it cannot well be said to be attached to the cape. — zenibako_trek zenibako_trek2023

anchorage beyond the cape

Proponent: zenibako_trek（小樽銭函地名歴史研究会） (zenibako_trek (Otaru Zenibako Place-Name and History Society))

kusi is the possessive form of kus, and the phrase is an Orofure construction; word for word, the anchorage whose head is on the far side.
