Benesse Star Dome

The Star Dome is a planetarium run by the Benesse Corporation. It’s located 100 metres above ground in Benesse’s Tokyo head office building. Around 6,500 stars are projected onto the dome-shaped screen, which has a diameter of 14m. As Japan’s first planetarium with power reclining seating, you can gaze up at the stars in the most comfortable position possible. Among the programs they screen are films featuring their popular character Shimajiro, making the planetarium a hit with kids too. The Star Dome is open on Saturdays, Sundays, national holidays and during the school spring and summer holiday periods, but it’s also possible to organize visits on weekdays for groups of twenty or more.
