The Shimane Arts Center in Masuda combines galleries and performance spaces. Opened in 2005, and designed by Naito Hiroshi, the rectilinear boxes of the design is unusual in being clad by more than 250,000 rooftiles, hence the building is commonly known as Grand Toit, from the french for big roof.
The rooftiles were made up the coast at Gotsu in the reddish-brown color typical of the region.
Externally the design is not particularly noteworthy, but inside is spectacular.
