Understanding the History of Hansen’s Disease in Japan

National Sanatorium Nagashima Aisei-en Museum


The museum was conceived as a way to educate the public on the history of Hansen’s Disease in Japan. Its facilities are made up of sections of the sanatorium that went into disuse as the number of patients dwindled over the years.

There are several centers with information in audio-visual format as well as photo galleries and a library. Tours are available provided reservations are made in advance.

The museum is located on Nagashima Island, which is right off the Setouchi City mainland. As with all of the islands of the inland sea, it is a wonder of natural beauty.

In addition to visiting the museum, you can take some lovely nature walks along wonderfully laid out set paths.

Access to Nagashima Island is now possible by bus as a bridge connecting it with Oku Town, Setouchi City opened in 1988.

About the Area

Setouchi City is a municipality that extends from the coast to the  hinterland of southeastern Okayama Prefecture. Accordingly, both fishing and agriculture play an important role in the lives of its residents.

The city is comprised of the towns of Oku (the location of city hall), Osafune and Ushimado, with each having its own unique quality.

Oku Town is the commercial and political center of the city, with a number of shopping centers, supermarkets and restaurants to choose from.

Osafune is thought to have the quintessential Japanese rural landscape, as its mountains and hills frame a picture perfect vista that includes streams, valleys and fields full of all manner of crops.

Ushimado is the seaside district of the city, which oddly enough is home to quite a few dairy farms. In fact Ushimado literally means “cow window”.

Historically, an important trading center, today, Ushimado has reinvented itself as a resort destination. There are top notch hotels and excellent pensions throughout the town.

Access: Take the Ako Line from JR Okayama Station to JR Oku Station. Take the Aisei-en bound bus from Oku Station to the Aisei-en Iri guchi bus stop. The National Sanatorium Nagashima Aisei-en Museum is about a 2 minute walk from the Aisei-en Iri guchi bus stop.
