On clear nights, planets (Jupiter, Saturn, Venus, Mars), the International Space Station, meteor showers, and brighter deep-sky objects like the Pleiades and Andromeda Galaxy are visible to the naked eye from Tokyo. Binoculars add dozens more.

Question 4

Does StarsOut work in Tokyo?

Yes. StarsOut works anywhere in the world — Tokyo has a dedicated page with tonight's score, the 7-night forecast, and a list of planets, comets, and deep-sky objects visible from your exact location.
