Overview
Coastal Watchtower is not presently verifiable as an official location name in the base game of Ghost of Yōtei. Available guides instead document several separately named watchtower locations, most notably Oshima Coast Watchtower, a story-gated passage in the Yōtei Grasslands, and Crow’s Nest Watchtower, an exploratory landmark northwest of the Old Inn.
This distinction matters. Oshima Coast Watchtower is connected with progression into the Oshima Coast region, while Crow’s Nest Watchtower is an optional vantage point containing a named item. They belong to different location hierarchies, serve different purposes, and should not be presented as one broad “coastal watchtower” area.
This draft records the verified information available for both locations while keeping their boundaries and progression states separate.
