The H-II launch vehicle display features a real first-stage main engine (LE-7) that underwent extensive testing.
The Kibo module replica on display is a full-scale model used by astronauts for training before flight.
The 'Space Dome' name refers to the distinctive architectural roof structure of the exhibition hall.
Exhibits include a retired satellite that was used for maritime observation and disaster monitoring.
The facility displays the actual capsule used in the HOPE-X experimental spaceplane project.

The Space Dome at the JAXA Tsukuba Space Center serves as the primary public exhibition facility for Japan’s national aerospace research agency. It houses a collection of retired flight hardware, including full-scale engineering models of the H-II rocket engine and the Japanese Experiment Module (Kibo) mock-up. The facility showcases the evolution of Japan's satellite technology, including early meteorological and Earth observation units. Visitors can observe the scale of space exploration through displays that detail the development of the H-IIA and H-IIB launch vehicles. The hall integrates technical data with physical artifacts to illustrate the history of Japanese space missions. The site is located within the larger Tsukuba Science City, which clusters various national research institutes.

Check the official JAXA website for required advance reservations, as entry protocols can fluctuate.
Visit the 'Planet Cube' gift shop on-site to find JAXA-branded space food and mission-specific merchandise.
Bring a camera with a wide-angle lens, as the rocket engine displays are massive and difficult to capture in a single frame.
Do not attempt to enter restricted research laboratories or office buildings; stick strictly to the marked public exhibition routes.
The facility is typically closed on certain Mondays and during year-end/new-year holidays.
