The entrance to the Ehime Science Museum is through a perfectly conical atrium.

From there steps lead down to an underground tunnel that leads to the planetarium.

Information and photos of the planetarium can be found here, and photos of the outside of the museum complex can be found here.

The museum was designed by Kishi Kurokawa and it opened in 1994

It is located in Niihama, Ehime, and entrance is 500 yen for adults.

Ehime Science Museum

The Ehime Prefectural Science Museum is situated on the hillside overlooking Niihama and the Inland sea.

It opened in 1994 and was designed by Kisho Kurokawa, an internationally-renowned Japanese architect who I am not very familiar with, but I have seen his Mojiko Retro Tower.

The complex of buildings uses geometric shapes... cone, triangle, cube, sphere,  semi-circles etc as well as a large reflective pool.

Embodied in the concrete is titanium, granite, and marble.

The museum is open from 9 to 5 daily, except Mondays. Entrance is 500yen
