2026 Full-Day Starry Sky Course at Yoshikawa City Children's Center Wonderland

Children's Center Wonderland in Mina, Yoshikawa City, Saitama Prefecture, has an observation room called 'Ginga no Heya' (Galaxy Room) equipped with a large telescope. The observation event is held about once a month, on a Saturday from 19:00 to 20:30, with a capacity of 30 people; entry is by online lottery application starting about a month before the event, so participation is not guaranteed. Regular planetarium viewing is free for city residents and 200 yen for non-residents.
