Science Square Tsukuba showcases research from AIST, one of the institutions that gives Tsukuba its science-city identity. Exhibits introduce robotics, energy, materials, measurement, and other applied technologies in a compact public-facing setting.
It is best for visitors who want Tsukuba to feel different from a generic suburb or university town. Pair it with other research-related stops, especially JAXA, to understand why the city was planned around laboratories.
