Naoshima (直島) is an island in the Seto Inland Sea that is known for its modern art museums, architecture and sculptures. Part of Kagawa Prefecture, the island with its Mediterranean atmosphere, sandy beaches and sunny weather, combined with a laid back, rural feel is a relaxing getaway from Japan's large urban areas.
 

The island is one of the main venues of the Setouchi Triennale art festival, displaying one of the highest densities of artworks among the participating ports and islands. In 2013, the Ando Museum dedicated to architect Ando Tadao, joined the many permanent art pieces already found across Naoshima.

By Ferry
One or two buses per hour from Miyanoura Ferry Terminal bound for Tsutsujiso that stop at the Nokyo-mae bus stop in Honmura (5 minutes, \100) along the way. 
By bicycle
It is a 2.5 kilometer bicycle ride (10 minutes) or walk (35-45 minutes) from the Miyanoura Ferry Terminal. Honmura has also its own port with infrequent ferry connections to Uno Port on Honshu.

The Art House Project takes empty houses scattered about residential areas, and turns the spaces themselves into works of art, weaving in the history and memories of the period when the houses were homes. Meetings between visitors to the island and the island's people in places where they go about their daily lives also provide occasions for a variety of interesting encounters.

The art houses are scattered throughout town, and most of them are unassuming from the street, blending into the surrounding traditional Japanese neighborhood. The interior of each, however, has been given over to artists to convert into whatever suits their artistic vision.
