The facility's planetarium dome is certified by Guinness World Records as one of the largest in the world.
The name 'Tamarokuto' represents the union of the six cities of Kodaira, Higashimurayama, Kiyose, Higashikurume, Nishitokyo, and Tanashi (now part of Nishitokyo).
The 'Chiron' projector utilized in the dome can replicate the night sky from any location on Earth at any point in time.
The building was designed by the architectural firm Sakakura Associates.
The center regularly hosts 'live' planetarium shows where staff provide commentary instead of using pre-recorded audio.
The 'Nature' room contains a collection of preserved specimens and local flora found specifically within the Musashino region.
Tamarokuto Science Center features one of the world's largest planetarium domes, measuring 27.5 meters in diameter. The facility is divided into five themed gallery spaces: Body, Mechanism, Nature, Universe, and Earth. The name 'Tamarokuto' is derived from the collaboration of six municipalities in the Tama area. Visitors can engage with interactive exhibits designed to explain complex scientific concepts through tactile learning. The center focuses on local natural history and regional geology alongside global scientific phenomena. A highlight is the 'Chiron' projection system, which displays over 140 million stars with high-resolution clarity. Outdoor areas include a landscaped park environment surrounding the building.

Check the planetarium show schedule upon entry, as these require specific timed-entry tickets.
Visit the 'Lab' areas for scheduled hands-on workshops that change frequently based on the season.
Pack a lunch to utilize the designated eating areas if staying for the full day.
Do not expect to see all exhibits without a planetarium reservation; the planetarium is the core draw and tickets often sell out.
Closed on Mondays (or the following weekday if a national holiday falls on a Monday), and during the New Year holiday period.
