Tsukuba, Ibaraki. It’s the science city of Japan. The Tsukuba Expo Center (as shown in the picture) could possibly be the symbol of Tsukuba. The planetarium is located here, .. blocked by a big tree, can you find it from the picture? The location of the Expo Center which is beside a beautiful park, makes it a perfect place to hangout after a busy schedule or a tough ‘scientific experiment’!
