Starry sky event calendar 2026
To a special seat at an altitude of 1,000 meters. In 2026, we go to see the glow of the meteor that colors Yatsugatake.
Yatsugatake, one of Japan's leading starry sky viewing spots. Experience the memories of the whole family with the "early plan" tailored to the maximum day of the meteor shower.
The Yatsugatake area, including the three major meteor showers, is a spot with many opportunities to meet shooting stars. Because the sunny weather rate is high and the altitude is high, the darkness of the sky that is not found in the city and the transparency are ideal for starry sky observation.

Recommended meteor shower
Perseus meteor shower
Weather changes are large and it is not always visible, but this time is the time when the Milky Way is clearest, and you can enjoy the overwhelming number of stars and meteors!
Gemini meteor shower
It is a season when the weather is very stable and you can observe the starry sky almost every day. There are many meteors, so you can enjoy it for a relatively long time.
Hotel observation location
Yatsugatake SoRa deck
This is the observation deck on the roof of the hotel. It is a place with a 360-degree view, and it is a superb view spot where you can enjoy the stars of the sky.

If it is sunny, a starry sky observation party is held every day from 20:00 to 21:30.
※A slide show will be held on the first basement floor when the stars are not visible.

A large telescope is installed in the dome, so you can enjoy a guide by specialized staff during the starry sky observation party.
