Main image

The Edo-Tokyo Open Air Architectural Museum is an open-air museum in western Tokyo that preserves and displays historic buildings from the Edo period through the early Showa era. It presents original structures relocated from around the Tokyo region and reconstructed on site to illustrate changing building types and urban form.

Exhibits include traditional merchant houses, rural farmhouses, a public bathhouse and Western-influenced residences, arranged in outdoor plots to recreate streetscapes and village scenes. The site runs demonstrations, guided tours and seasonal events that explain traditional construction techniques and daily life in historical Tokyo.

The museum was created to safeguard representative buildings that could no longer remain in their original urban contexts and to provide a hands-on learning environment about architectural and social history. Conservation and reconstruction work is an ongoing part of the museum’s activity.

The museum sits within Koganei Park in the city of Koganei in western Tokyo and is reachable by public transport from central Tokyo.

  • Number of buildings: Around 30 historic buildings have been moved to the site and rebuilt to preserve urban and rural architectural types from the Edo to early Showa eras.
  • Location: Located inside Koganei Park, the museum is accessed from western Tokyo and is commonly visited as part of a trip to the park and nearby suburban cultural sites.

What to See #

  • Historic buildings collection: A collection of approximately 30 relocated and reconstructed buildings that represent urban and rural architecture from the Edo through early Showa periods, including merchant houses, farmsteads and a traditional public bathhouse.

How to Get to Edo-Tokyo Open Air Architectural Museum #

The Edo‑Tokyo Open Air Architectural Museum is located inside Koganei Park in Koganei City.

Tips for Visiting Edo-Tokyo Open Air Architectural Museum #

  • Plan a weekday or an opening-hour visit (often mornings) to avoid weekend families and school groups-later afternoons on weekdays are also quieter.
  • Combine the museum visit with a stroll through Koganei Park since the open-air exhibits are spread across the park and make for an easy half-day outing.
  • Check the museum's website for special house interiors or scheduled demonstrations; some relocated buildings open their interiors only at specific times and are easy to miss if you just walk the grounds.
