The planetarium was opened in 2011, when much of the museum was renovated.
Two years later, the Science & Technology Building was added and later the Life Science Building in 1982.
The museum was one of the best comprehensive science-museums in Japan.
But 50 years later the old projector began showing signs of aging.
The museum remained closed for nearly seven months.
Unfortunately, the presentations are given only in Japanese.
