Stargazing in Japan: a visitor's guide
Japan has surprisingly dark skies once you leave the big cities. Here is when and where to go, and what you can see that you might not see at home.
Best seasons
- Autumn and winter (October–February) — the clearest, driest air on the Pacific side (Tokyo, Nagoya, Osaka, Kyushu). Orion, the Pleiades and the Geminids (mid-December) are highlights.
- Spring (March–May) — hazier skies, but mild nights. Good for Jupiter, Leo and the spring galaxies with binoculars.
- Summer (June–August) — the rainy season ends in July; after that, the Milky Way runs high overhead. The Perseids peak around August 12–13.
Where to go
- Hokkaido — wide, dark plains and very cold, clear winter nights. Dress for well below freezing.
- Nagano and the Japan Alps — high-altitude villages such as Achi in Nagano promote themselves as stargazing destinations.
- Okinawa and the Yaeyama Islands — far enough south to see the Southern Cross low on the horizon in spring, and the bright star Canopus in winter.
- Anywhere a short train ride from a city — even an hour from Tokyo the number of visible stars rises dramatically.
Practical tips
- Check the Moon
A bright Moon hides faint stars. Plan around the new Moon. - Check the weather by region
In winter the Sea of Japan side is often cloudy while the Pacific side is clear. - Let your eyes adapt
Give it 15 minutes without looking at a bright phone screen. - Be considerate
Many good spots are farmland or parking areas — keep lights low and voices down.
