Edo-Tokyo Open Air Architectural Museum

The Edo-Tokyo Open Air Architectural Museum (江戸東京たてもの園, Edo Tōkyō Tatemono En, lit. "Edo Tokyo Buildings Garden") is an open-air museum located within Koganei Park, Tokyo, Japan. It opened in 1993 as a branch of the Edo-Tokyo Museum and is operated by the Tokyo Metropolitan Foundation for History and Culture, a public interest incorporated foundation. The museum relocates and reconstructs buildings that originally stood in Tokyo (formerly Edo) from the Edo period through the mid-Showa era, which could no longer be preserved at their original locations, and presents them as part of the city's cultural heritage. The site covers an area of 70,164 m² (17.338 acres).

The museum grounds feature 30 restored structures, including the private residences of politicians, entrepreneurs, architects, and farmers from different historical periods, as well as traditional businesses such as an izakaya (Japanese-style pub), a sentō (public bathhouse), and a ryokan (traditional inn). These buildings recreate the appearance of historic Japanese streetscapes, and visitors are able to enter and explore their interiors.

The origins of the open-air museum date back to 1934 with the opening of the Tokyo Kyōdo Shiryō Chinretsukan (lit. "Tokyo Local History Exhibition Hall") in Arisugawa-no-miya Memorial Park. In 1948, it was relocated to Inokashira Park and renamed the Musashino Hakubutsukan (lit. "Musashino Museum"). In 1954, it was moved again to Koganei Park and reopened as the Musashino Kyōdokan (lit. "Musashino Folklore Museum"), which remained in operation until 1991.

The animator Hayao Miyazaki often visited here during the creation of his film, Spirited Away, for inspiration.
