JR East to rebuild Musashisakai station with a retail floor and an eight-storey hotel wing
JR East will start building a new Musashisakai station complex in October, pairing a single retail floor with an eight-storey hotel wing — the latest instance of the ekinaka retail-and-hotel format the railway keeps building into its Tokyo commuter stations rather than developing separately nearby.

East Japan Railway Company (JR East) said it will start construction in October 2026 on a new station building directly connected to Musashisakai Station on the Chuo Line, adding a ground-floor retail zone and a hotel wing at the Tokyo commuter stop, according to a release dated September 30.
