Local sky character in Akaiwa
Northern mid-latitudes · northern hemisphere · 27 m elevation
- The north celestial pole stands 36.2° above the horizon, so stars within 36° of it never set from here.
- About 79.5% of the whole sky rises above the horizon at some point in the year from this latitude.
- The Milky Way's core in Sagittarius culminates about 24.8° up, staying low, so a clear southern horizon matters.
- At 27 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Akaiwa is small enough that local light domes are limited — on a clear, moonless night the Milky Way is realistically within reach.

Best nights this month in Akaiwa
Calculated for these coordinates and today's date — not a fixed list.
- 2026-08-12 — Darkest night of the coming month
The Moon is only 0% illuminated, giving the least lunar interference in the next 30 nights — the best window for the Milky Way and faint deep-sky targets from Akaiwa, Gunma, Japan.
- 2026-08-12 — Perseids peak — up to 100/hour
Radiant in Perseus. Favours the Northern Hemisphere, which includes Akaiwa, Gunma, Japan. The Moon is 2% lit on peak night, so lunar interference is none.
- 2026-08-27 — Full Moon
A 100%-lit Moon washes out faint objects, but lunar terrain along the limb is at its most striking — plan bright targets and planets instead of deep sky.
Akaiwa, Gunma, Japan stargazing questions
- What can I see in the sky tonight from Akaiwa, Gunma, Japan?
- Tonight from Akaiwa, Gunma, Japan expect a new moon Moon at 0% illumination, with these naked-eye planets above the horizon after dark: Venus, Jupiter, Mercury, Saturn, Mars. The night offers about 7.2 hours of true astronomical darkness.
- Does Akaiwa, Gunma, Japan's elevation help stargazing?
- At 27 m you are above a meaningful fraction of the atmosphere, which reduces extinction and scintillation — the reason major observatories are sited high. Nobeyama Radio Observatory sits about 91 km from Akaiwa, Gunma, Japan at 1350 m.
- What should I plan for observing near Akaiwa, Gunma, Japan?
- High sites reward targets that suffer most from atmosphere: planets at high altitude, faint nebulae, and the Milky Way, which culminates around 24.8° here. Cold and thinner air are the practical constraints, not the sky.
- How dark does it actually get in Akaiwa, Gunma, Japan tonight?
- About 7.2 hours of astronomical darkness (Sun more than 18° below the horizon). That is the real observing window for faint objects; brighter targets are workable from dusk onward.
