Nagoya City Science Museum

Nagoya City Science Museum in Sakae holds the largest planetarium dome in Japan, and the 35-meter sphere is visible from outside as the building's dominant visual element. Inside, the astronomy shows use a projection system capable of rendering 130 million stars across the curved ceiling. The broader museum covers topics from chemistry and biology to weather and materials science through interactive and hands-on exhibits spread across multiple floors. A genuine tornado simulator and a large lightning display are among the more memorable installations. Tickets for the planetarium sell out quickly, particularly on weekends, so booking in advance through the museum website is strongly recommended.
