Nihon Minka-en, Open-air folk house museum in Tama Ward, Japan.

Nihon Minka-en is an open-air museum in Tama that houses 25 traditional buildings from different regions of Japan, including farmhouses, merchant structures, and fishing village dwellings. The buildings display the varied architectural styles and living arrangements that existed across different areas.

The buildings date from the Edo period and were carefully dismantled from their original locations, transported, and reconstructed on the museum grounds. This process preserved construction methods and living arrangements that might otherwise have disappeared.

The craft demonstrations show how people once performed their everyday work, especially with natural dyeing techniques for textiles. Visitors can watch these skills in action and see how they shaped daily life in communities.

The museum is about a 15-minute walk from Mukogaoka-Yuen Station on the Odakyu Odawara Line, or a 3-minute walk from the Ikuta Ryokuchi Iriguchi bus stop on the Kawasaki city bus Mi-19 line. It closes on Mondays, the day after public holidays, and over the New Year period. Hours run 9:30 to 17:00 from March to October and to 16:30 from November to February. Parking is available at Ikuta Ryokuchi for a fee.

The open-air museum holds 25 buildings on the hillside of Ikuta Ryokuchi, among them 7 nationally designated Important Cultural Properties (9 structures) and one Important Tangible Folk Cultural Property, the Kabuki stage from Shima. The Japan Institute of Architecture gave the park its Prize for Achievement for systematically collecting, preserving and opening early-modern minka.
