Nihon Minka-en, also known as the Japan Open-Air Folk House Museum, is a remarkable open-air museum located in Kawasaki, Japan. It features a carefully preserved collection of 25 traditional Japanese folk houses (minka) that have been relocated from different regions of the country, offering visitors a fascinating glimpse into rural life during the Edo period.
The museum showcases an impressive variety of historic buildings, including merchant houses, post-town inns, fishing village homes, a shrine, and a traditional Kabuki theatre stage:
(The Hara House, the Suzuki House, Sasaki House, Water Mill, the Emukai House, the Hamada House, the Nohara House, the Yamashita House, the Sakuda House, Storehouse on stilts, the Hirose House, the Ota House, the Kitamura House, the Kiyomiya House, the Itoh House, the Kokagesan House, the Iwasawa House, Kabuki Stage from Funakoshi, Ferryman’s Hut, the Kudo House, the Saji House Gate, the Misawa Medicine House, the Watermill), its highlights are the striking gassho-zukuri farmhouses from the mountainous regions of Gifu and Toyama Prefectures, renowned for their steeply pitched thatched roofs. Several of the houses are furnished with authentic period furniture, household items, and decorations, allowing visitors to imagine everyday life centuries ago.
On Sundays, the museum hosts demonstrations and workshops showcasing traditional Japanese crafts, including indigo dyeing, straw and bamboo weaving, and cloth weaving. For anyone interested in Japanese history and culture, they can visit the Folk Museum displaying an excellent collection of Edo-period farming tools, household implements, etc, making it especially rewarding.
The museum is about a 15-minute walk from Mukogaoka-Yuen Station on the Odakyu Odawara Line (approximately 20 minutes by express train from Shinjuku; ¥250), or a 25-minute walk from Noborito Station on the JR Nambu Line (approximately 30 minutes from Kawasaki Station; ¥310).
If you enjoy soba, don’t miss Soba-dokoro Shirakawa, a traditional soba restaurant housed within one of the relocated merchant homes. Dining in such an authentic historic setting is an experience in itself.
Admission is very reasonable at ¥500 for adults, ¥300 for university and high school students, and ¥200 for elementary and junior high school students. The museum is open daily from 9:30 a.m. to 5:00 p.m.
On weekends, visitors may also encounter volunteer demonstrations of traditional folk activities. There is also an indigo dyeing workshop where visitors can learn more about this centuries-old craft.
Anyone with an interest in Japanese architecture, cultural history, or traditional craftsmanship will thoroughly enjoy this museum. It is a peaceful and rewarding destination that deserves at least two to three hours to explore. Be prepared for a fair amount of walking, including several flights of stairs, as the grounds are spread across a gently hilly landscape.
In a country celebrated for its modern cities and iconic landmarks, Nihon Minka-en offers something quieter and more enduring—a chance to step back in time and experience the spirit of old Japan at an unhurried pace.

For foreign visitors wondering whether to visit this museum, I would suggest that you *first* visit the Edo Tokyo Open Air Architectural Museum (located on the west Chuo line, past Kichijoji -- a similar distance from Shinjuku) *before* seeing this one.
This museum is ok and fine, but basically you see the same farmhouse structure 25 times in a walking loop. Think, the village farmhouses from "The Seven Samurai". They're in different settings of course but pretty much the same inside, not much difference to the average eye (at least it seemed to me).
There are some volunteer folk activities happening here on weekends (basket weaving, hearth fire tending), and an indigo dyeing shop to visit. But by comparison, the Edo Tokyo museum has a far greater variety of houses, especially of the classic Showa era, that are more interesting in my view. Also, not that it's a lot of money, but the Edo Tokyo museum is a bit cheaper. And seems a bit better maintained.
See photos for what the houses here basically look like. It was pleasant enough to visit on an extra day I had. But for those with more limited time, I would suggest the above first. Best wishes!
