How long is the daylight duration in Tokyo across different seasons?

At latitude 35.68°, Tokyo experiences temperate seasonal variations. Daylight stretches to approximately 14–15 hours during mid-summer and contracts to roughly 9–10 hours during mid-winter.

When are the Golden Hour and Blue Hour in Tokyo?

The morning Golden Hour begins at sunrise and lasts for approximately 45–60 minutes, while the evening Golden Hour starts about an hour before sunset. The Blue Hour occurs immediately following sunset (and before dawn) during civil twilight when the sun is between 0° and 6° below the horizon, creating vivid deep blue and indigo skylines across Tokyo.

When does Solar Noon occur in Tokyo?

Solar Noon in Tokyo is the exact astronomical instant when the sun crosses the local meridian (139.65° longitude) and reaches its maximum daily elevation. Depending on the time of year (the Equation of Time) and whether daylight saving time is active, Solar Noon generally falls between 11:45 AM and 1:30 PM in the Asia/Tokyo zone.

How long does civil twilight last in Tokyo?

In Tokyo, civil twilight typically lasts between 25 and 45 minutes after sunset. Because the angle at which the sun sinks below the horizon depends on latitude (35.68°), twilight duration increases in the summer months and is longer than in equatorial regions.

Geographical Solar Characteristics

Solar Profile & Seasonal Cycles in Tokyo

Positioned at 35.6762° latitude and 139.6503° longitude, Tokyo operates under the Asia/Tokyo time standard. The local solar trajectory is determined by Earth's axial tilt relative to Tokyo's geographic latitude:

Hemisphere & ZoneNorthern Hemisphere • Temperate Zone

Longest daylight occurs around June 21; shortest daylight occurs around December 21.

Atmospheric Refraction Lift+34 Arcminutes (~0.566°)

Atmospheric bending causes the sun to become visible approximately 2.5 to 3.5 minutes prior to true geometric sunrise in Tokyo.

Solar Noon VarianceEquation of Time Drift

Depending on the time of year, true astronomical midday in Tokyo deviates from clock midday by up to ±16 minutes due to orbital eccentricity.

Cinematography & Photography Protocol

Golden Hour & Blue Hour Photography Windows in Tokyo

For landscape photographers, videographers, and creators in Tokyo, the hour surrounding sunrise and sunset provides the most flattering, diffuse natural lighting:

Golden Hour (Warm Spectrum)Sun +6° to 0°

Light rays travel through extensive atmospheric air masses, scattering high-frequency blue photons and bathing Tokyo's skyline and landscapes in warm amber, gold, and terracotta hues with long, soft shadows.

Blue Hour (Indigo & Cobalt)Sun 0° to -6°

Occurring during civil twilight, Chappuis ozone absorption filters longer red wavelengths, producing balanced cobalt twilight skies that contrast against the warm artificial architectural lighting of Tokyo.
