Koganei park, north from Musashi-Koganei station in Tokyo, is located near the workplace of Studio Ghibli artists. Part of the park is occupied by the Edo-Tokyo Open Air Architectural Museum (江戸東京たてもの園) where there are several streets with reconstructions of houses of the Edo era. Not only the outer part of the houses is faithful to the Edo era architecture, but also the inner part of the houses carefully represents the houses of the time.
What I like the most about this museum is that, apart from Edo era buildings, there is a commercial street with shops from the Edo era. For example, you can see how a pharmacy or the public baths were 150 years ago in Tokyo.
