Tonight's sky above Uenohara, Yamanashi, Japan
Whether tonight is a good night for stargazing from Uenohara, Yamanashi, Japan comes down to four real things: the Moon phase, cloud cover, which planets are up, and the current Kp index.
Above Uenohara, Yamanashi, Japan tonight (35.62°, 139.12°), expect a new moon moon at 0% illumination. The night gives 7.3 hours of true astronomical darkness. At 35.6°, aurora needs a strong storm — roughly Kp 9 or higher — to reach Uenohara, Yamanashi, Japan.
Local sky character in Uenohara
Northern mid-latitudes · northern hemisphere · 165 m elevation
- The north celestial pole stands 35.6° above the horizon, so stars within 36° of it never set from here.
- About 79.1% 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 25.4° up, staying low, so a clear southern horizon matters.
- At 165 m elevation, roughly 2% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Uenohara 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 Uenohara
Calculated for these coordinates and today's date — not a fixed list.
- 2026-08-13 — 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 Uenohara, Yamanashi, Japan.
- 2026-08-28 — 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.
Uenohara, Yamanashi, Japan stargazing questions
- What can I see in the sky tonight from Uenohara, Yamanashi, Japan?
- Tonight from Uenohara, Yamanashi, 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 7.3 hours of true astronomical darkness.
- Does Uenohara, Yamanashi, Japan's elevation help stargazing?
- At 165 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 68 km from Uenohara, Yamanashi, Japan at 1350 m.
- What should I plan for observing near Uenohara, Yamanashi, Japan?
- High sites reward targets that suffer most from atmosphere: planets at high altitude, faint nebulae, and the Milky Way, which culminates around 25.4° here. Cold and thinner air are the practical constraints, not the sky.
- How dark does it actually get in Uenohara, Yamanashi, Japan tonight?
- About 7.3 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.
