READING TONIGHT'S SKY…
How dark is the sky over Tokyo?
Sky class (estimate)Bortle 9 · Inner-city sky
The Kantō plain is one of the largest light domes on Earth — Bortle 8–9.
Even on the clearest, Moonless night, a bright city sky limits what you can see. For the Milky Way and faint stars from Tokyo, you'll want to reach a darker site — see the options below.
