The 25.6-meter planetarium dome was once recognized as the largest in the world when it opened.
The facility is home to the 'Science Square' exhibition area, which uses advanced robotics to interact with visitors.
The iconic H-II rocket replica standing outside is a 50-meter scale representation of the real vehicle used by JAXA.
The center is physically located within the 'Azuma' district, which was specifically developed to support the needs of the nearby research community.
The planetarium uses a hybrid projection system combining traditional optical stars with ultra-high-resolution digital displays.
The Tsukuba EXPO Center is a science and technology museum located in the heart of Tsukuba Science City, featuring one of the world's largest planetarium domes with a 25.6-meter diameter. It was originally established to commemorate the International Exposition of 1985 held in Tsukuba. The facility houses interactive exhibits focused on space exploration, robotics, and fundamental physics. Visitors can view a full-scale model of the H-II launch vehicle displayed prominently outside. The center operates a digital planetarium system that provides high-definition astronomical projections. Its exhibitions change periodically to showcase contemporary research developments from nearby institutes. The museum caters specifically to STEM education through hands-on experimental stations and workshops. It serves as a regional hub for science communication, linking local academic research with public outreach.

Check the planetarium schedule immediately upon arrival, as popular shows fill up quickly on weekends.
Prioritize the outdoor rocket exhibit early to avoid mid-day glare in your photographs.
Visit the science shop for unique, locally-themed space educational merchandise.
Do not overlook the smaller hands-on science stations tucked into corners; many visitors miss these in favor of the larger displays.
Typically closed on Mondays; always closed during the year-end and New Year holidays.
