2026 Goshiki Onsen Auto Camp Site Starry Sky: A Full-Day Course

Goshiki Onsen Auto Camp Site (五色温泉オートキャンプ場), at 498 Itaya, Yonezawa City, Yamagata Prefecture, is open year-round (opening hours 10:00-20:00, reception until 17:00, closed Wednesdays). Located in the mountains at an elevation of 800m, it cannot be reached by public transport, so a private car is essential. Stargazing here requires an overnight stay (auto camping), and check-in must be completed by 17:00 when reception closes. Hot spring bathing costs 1,000 yen per person (including bathing tax; included in the site fee for overnight guests), and the sauna is on a 60-minute system (hot spring bathing fee included; not available to elementary-school-age children or younger). For safety, guide lights to the restroom stay on even after lights-out, but their impact on stargazing is said to be minimal. Campsite fees vary by plot, so please check the official website (goshiki-camp.com) when booking.
