Museum of the Imperial Collections Closed for Expansion Until Autumn 2026

The Museum of the Imperial Collections, Sannomaru Shozokan, is currently closed while expansion and renovation work continues.

Located in the East Gardens of the Imperial Palace in central Tokyo, the museum preserves and displays cultural masterpieces formerly owned by Japan's Imperial Family.

The expansion project is intended to provide substantially larger exhibition and storage facilities, improving public access as well as the conservation and management of the collection.

The museum's official website states that it will reopen in autumn 2026, but it does not currently list an exact opening date or upcoming English-language exhibitions. Travellers should therefore avoid treating an approximate seasonal date as a confirmed reservation date.

The closure applies to the museum, not necessarily to the entire Imperial Palace East Gardens. Visitors planning to see the gardens should check their separate opening calendar, entry rules and temporary closure notices.
