Otsu City Science Museum

The Otsu City Science Museum (大津市科学館), located on the second floor of the Otsu City Lifelong Learning Center, offers a fun and educational experience just minutes from the shores of Lake Biwa. A highlight of the museum is the planetarium, where visitors can enjoy narrated star shows, animated night skies, and seasonal astronomy programs. Additional exhibits focus on the natural environment of Shiga Prefecture, featuring displays on regional wildlife, ecosystems, and the formation of Lake Biwa—making it a fascinating stop for those curious about both space and local science.

On the third floor, guests can dive into a hands-on science zone designed to engage all ages. Interactive exhibits let visitors experiment with physical forces, light, and magnetism, encouraging playful learning through discovery. The popular “Waku Waku Science” show—a live science demonstration held on weekends and national holidays at 1:10 p.m.—is especially loved by families and school groups. With accessible exhibits and family-friendly programming, the museum provides a perfect mix of entertainment and education for curious minds.
