Tsukuba Expo Center

Ibaraki, Kanto

People can enjoy learning about the latest science and technology through one of the world's largest planetariums and experience-based exhibits.

Tsukuba Science City is located at the center of Tukuba-shi, Ibaraki. An International Science and Technology Exposition, “Science Exposition-Tsukuba Expo ’85,” was held there in 1985. Tsukuba Expo Center is a museum of science which was built on the occasion of the exposition.

The theme of this facility is “See, touch, and enjoy learning.” There are many experience-based exhibits, such as “Air Bazooka,” which shoots air like a bullet, “Sun Cruiser,” enabling you to have a simulated travel to the sun with overwhelming stereoscopic images and sounds, and “Yurugiishi,” enabling you to move a 50 ton stone. Therefore, people of all ages enjoy getting close to science here.

The chief feature of Tsukuba Expo Center is one of the planetarium which is one of the world. A realistic, beautiful starry sky is reflected on a dome with a diameter of 25.6 meter by using a state-of-the-art digital projector. Even those who are not good at science and math will become much more interested in science. Please visit Tsukuba Expo Center.
