RV Park Yatsugatake Kougen "Genson" Mominoki
RV Park

The closest RV park to the Japan's starry sky!
  • RV Park Yatsugatake Kougen "Genson" Mominoki

  • RV Park Yatsugatake Kougen "Genson" Mominoki

An RV park at an altitude of 1,200m, closest to the starry sky in Japan. Visitors will be surprised by the cool, low humidity and comfortable environment even in summer.
Haramura is also known as a “starry village”. In the summer, at the Yatsugatake Natural Cultural Park, which is about 1 km above from here, the "Star Festival" where astronomical fans gather from all over the country will be held for three days.
In addition, the “Stardust Theater in Haramura” is held every day in the same place from early to late August. This is also a plateau theater closest to the starry sky.
In addition, there are many other fun events, such as a refreshing concert on the plateau, so it would be nice to be able to "search" for event dates on the "Haramura" website.
We look forward to your visit.
