Moon Phase in Tokyo Tonight

Moon Phase Tonight in Tokyo

The current moon phase visible from Tokyo is Waxing Crescent with 4% of the lunar surface illuminated by direct sunlight. A thin sliver of the Moon is now visible on the right side (in the Northern Hemisphere). The illuminated portion grows each night as the Moon moves further from the Sun in the sky.

From Tokyo at latitude 35.7° and longitude 139.7°, the Moon rises at 06:04 and sets at 20:44 local time today. These times are specific to Tokyo's geographic coordinates and will differ from other cities, even those in the same time zone. The Moon's position in the sky depends on the observer's exact location on Earth.

The lunar cycle from one new moon to the next takes approximately 29.53 days (a synodic month). During this period, the Moon progresses through eight named phases. The illumination percentage tells you how much of the Moon's visible face is currently lit by sunlight as seen from Tokyo.

Understanding Moon Phases

The Moon does not produce its own light. What we see as moonlight is sunlight reflected off the lunar surface. As the Moon orbits the Earth every 29.53 days, the angle between the Sun, Earth, and Moon changes continuously, altering how much of the illuminated half of the Moon is visible from our perspective on Earth.

The eight principal moon phases are:

• New Moon: The Moon is between the Earth and the Sun. The illuminated side faces away from Earth, making the Moon invisible. Illumination is 0%.
• Waxing Crescent: A thin sliver of light appears on the right side of the Moon (in the Northern Hemisphere). Illumination grows from 1% to 49%.
• First Quarter: The right half of the Moon is illuminated. Despite the name "quarter," half the visible disk is lit. The Moon is one-quarter through its cycle. Illumination is 50%.
• Waxing Gibbous: More than half the Moon is illuminated and growing toward full. Illumination ranges from 51% to 99%.
• Full Moon: The entire visible disk is illuminated. The Moon is opposite the Sun in the sky, rising at sunset and setting at sunrise. Illumination is 100%.
• Waning Gibbous: The illuminated portion begins to shrink from the right side. Illumination decreases from 99% to 51%.
• Last Quarter: The left half of the Moon is illuminated. The Moon is three-quarters through its cycle. Illumination is 50%.
• Waning Crescent: A thin sliver of light remains on the left side, shrinking toward the next new moon. Illumination drops from 49% to 1%.

Moon Phases and Photography

The moon phase significantly affects both lunar photography and nighttime landscape photography in Tokyo. Each phase offers different creative opportunities.

Photographing the Moon

For detailed close-up photographs of the lunar surface, the best phases are the first quarter and last quarter. At these half-lit phases, sunlight strikes the Moon at an oblique angle, creating deep shadows along the terminator line (the boundary between the lit and dark halves). These shadows reveal craters, mountains, and valleys in sharp relief. A full moon, by contrast, is lit head-on and appears relatively flat with few visible surface features.

Recommended camera settings for lunar photography from Tokyo:

• Focal length: 200mm minimum, 400mm+ preferred for detail. A 2x teleconverter helps.
• Full Moon: ISO 100, f/11, 1/125s (the "Looney 11" rule).
• Crescent Moon: ISO 200 to 400, f/8, 1/60s. Adjust based on the illumination level.
• Quarter Moon: ISO 100, f/11, 1/60s to 1/125s.
• Tripod: Essential for focal lengths above 200mm to avoid motion blur.
• Remote shutter: Use a cable release or 2-second timer to minimize vibration.

Nighttime Landscape Photography

For night sky and Milky Way photography near Tokyo, the moon phase matters as much as light pollution. A bright moon washes out faint stars and the Milky Way core. Plan night sky sessions around the new moon when the sky is darkest. The five days centered on the new moon provide the best conditions for astrophotography.

Conversely, a bright moon (waxing gibbous to full) is excellent for illuminating foreground landscapes at night. The Moon acts as a natural fill light, allowing you to capture detailed foregrounds without light painting. Position the Moon behind you or to one side to light the landscape while keeping stars visible in the opposite direction.

Moonrise and Moonset in Tokyo

Today's moonrise in Tokyo occurs at 06:04 and moonset at 20:44. Unlike sunrise and sunset, which follow a predictable daily pattern that shifts by just one to two minutes per day, moonrise and moonset times shift by approximately 50 minutes later each day. This is because the Moon orbits the Earth in the same direction that the Earth rotates, so each day the Earth must rotate an extra 50 minutes for Tokyo to "catch up" to where the Moon has moved.

This daily 50-minute shift means the Moon's visibility window changes dramatically over the course of a month. Around the full moon, the Moon rises near sunset and is visible all night. Around the new moon, the Moon rises and sets close to the Sun and is not visible. During the first quarter, the Moon is visible in the afternoon and evening. During the last quarter, it rises around midnight and is visible through the morning.

The exact moonrise and moonset times depend on Tokyo's latitude (35.7°) and longitude (139.7°). Two cities in the same time zone but at different latitudes will see the Moon rise and set at different times. Cities closer to the poles experience greater variation in moonrise times throughout the month compared to equatorial locations.

On some days, the Moon may not rise or not set at all from Tokyo's perspective. This happens when the daily 50-minute shift causes moonrise to skip past midnight into the next calendar day. When the table shows "--:--" for moonrise or moonset, it means that event does not occur on that calendar date.

How the Moon Affects Tides in Tokyo

Tokyo experiences tidal patterns influenced by the Moon's gravitational pull. The Moon's gravity creates a tidal bulge on the side of the Earth facing the Moon and a second bulge on the opposite side. As the Earth rotates through these bulges, coastal areas experience two high tides and two low tides each day.

During full moons and new moons, the Sun and Moon align, combining their gravitational forces to produce higher-than-average "spring tides." During the first and last quarter phases, the Sun and Moon pull at right angles, partially canceling each other out and producing lower-than-average "neap tides." The current Waxing Crescent phase means Tokyo is between spring and neap tide conditions.
