Japan Moon Phase FAQ

On Saturday 10 October 2026, the moon phase today in Japan is a New Moon, with 0% illumination. Next full moon: 26 Oct. The Moon is about 29.0 days into its 29.5-day cycle.
The phase itself doesn't change from place to place — everyone on the night side of Earth sees the same phase at the same moment. What does shift across Japan is moonrise and moonset time, mostly with longitude: the main islands stretch about 16° from western Kyushu to eastern Hokkaido, which moves local rise and set times by roughly an hour even though the whole country shares one clock. The Moon's exact position in the sky also varies with latitude, which changes how high it arcs and at what angle the terminator sits.
All times on this page use Japan Standard Time (JST, UTC+9). Japan uses a single time zone nationwide and does not observe daylight saving time, so the clock never changes and the times shown for any Japanese city are already on that local clock.
A full moon happens roughly every 29.5 days — the length of the synodic month, the time it takes the Moon to cycle through all its phases as seen from Earth. That works out to about 12 or 13 full moons a year. Check the "Next Full Moon" figure on the calculator above for the exact upcoming date.
It's a latitude effect, not a different Moon. Japan sits between roughly 24°N (Okinawa) and 45°N (Hokkaido), so the Moon appears tilted at an angle between the horizontal "smiley face" crescent photographed in the tropics and the near-vertical terminator seen from northern latitudes. The further south in Japan you are, the flatter that tilt tends to be. See the "Moon Phases Explained" section further down this page for more on how each phase actually looks.

Moon Phases Explained

The Moon doesn't change shape — only the angle of sunlight across its surface does. As it orbits Earth over 29.5 days, that shifting angle produces eight distinct phases, each with its own character and its own best targets for observation.

How this looks from Japan

Japan spans a wide latitude range of its own — from subtropical Okinawa around 26°N up to Hokkaido near 45°N, with Tokyo sitting at roughly 35.6°N. That's noticeably lower than the UK or much of Europe, so the Moon's terminator appears somewhat less steep here, tilting closer toward the more horizontal orientation photographed nearer the tropics — though still well short of the pronounced "smiley face" crescent seen right at the equator. Japan also has one of the world's longest-running moon-viewing traditions: Otsukimi, held around the mid-autumn harvest moon, has been celebrated for well over a thousand years. Use the calculator above for exact moonrise, moonset, and phase times wherever you are in Japan.
