A photographer setting up at Nagoya Castle needs the golden hour, not a guess. A runner training along the Yamazaki River wants to finish before dark. Those are the reasons anyone looks up sunrise and sunset for this city. Here are the numbers that matter, drawn from the 2026 almanac.
How Nagoya’s sun shifts across the year
Nagoya sits at 35.181° N. Japan Standard Time stays fixed at UTC+9 all year. No daylight saving. No clock changes. That means the swing from a midwinter afternoon to a midsummer evening is purely seasonal, and it is stark.
The four anchor dates for 2026:
| Event | Date | Sunrise (JST) | Sunset (JST) | Daylight |
|---|---|---|---|---|
| March equinox | 20 March | 05:57 | 18:03 | 12 h 6 min |
| June solstice | 21 June | 04:37 | 19:09 | 14 h 32 min |
| September equinox | 22 September | 05:39 | 17:50 | 12 h 12 min |
| December solstice | 21 December | 06:56 | 16:43 | 9 h 47 min |
The longest day: June solstice
21 June 2026. Sunrise at 04:37. Sunset at 19:09. Fourteen hours and 32 minutes of daylight.
For a morning shoot at Atsuta Jingū, the sun is well above the treeline before 05:00. Arrive by 04:00 and you catch the full arc of golden light. The evening golden hour runs from roughly 18:15 until the sun drops. Blue hour kicks in around 19:30.
The shortest day: December solstice
21 December 2026. Sunrise at 06:56. Sunset at 16:43. Nine hours and 47 minutes of daylight.
The sun stays low all day. Shadows stretch long even at noon. The golden hour begins near 15:30 and runs to sunset. Blue hour follows, starting about 16:50. By 17:15 it is dark enough that any outdoor task needs artificial light.
Daylight through the seasons
The gap between the solstices is nearly five hours. That is the number to internalise.
- Spring (March equinox): 12 hours 6 minutes of daylight. Sunrise 05:57, sunset 18:03.
- Summer (June solstice): 14 hours 32 minutes. Sunrise 04:37, sunset 19:09.
- Autumn (September equinox): 12 hours 12 minutes. Sunrise 05:39, sunset 17:50.
- Winter (December solstice): 9 hours 47 minutes. Sunrise 06:56, sunset 16:43.
Around the equinoxes, day length changes fast: two to three minutes a day in March and September. Around the solstices, the curve flattens. For a week either side of 21 June, sunrise and sunset barely move.
Twilight: civil, nautical, astronomical
Twilight is not one thing. It is three bands, each useful for a different purpose.
- Civil twilight (sun 0-6° below the horizon): enough light to read a sign or walk a path. In Nagoya it lasts about half an hour after sunset and the same before sunrise.
- Nautical twilight (6-12° below): the horizon holds a line. Sailors and hikers use it.
- Astronomical twilight (12-18° below): the last glow before full dark. Astrophotographers care about this cutoff.
In June, civil twilight starts near 03:45. In December, it starts closer to 06:10.
Golden hour and blue hour for photographers
Nagoya Castle, Atsuta Jingū, the skyline from Oasis 21: all of them look different under low-angle light. The golden hour is the sixty minutes after sunrise and the sixty before sunset. The blue hour is the twenty to thirty minutes after sunset or before sunrise when the sky goes cobalt.
Approximate windows:
- Morning golden hour: 04:40 to 05:40 in June; 06:00 to 07:00 in December.
- Evening golden hour: 18:10 to 19:10 in June; 15:45 to 16:45 in December.
- Evening blue hour: 19:15 to 19:40 in June; 16:50 to 17:15 in December.
These shift daily. For a precise readout on a specific date, use the calculator embedded on the page.
Why Nagoya’s latitude matters
At 35.181° N, Nagoya sits midway between the equator and the Arctic Circle. That gives it a summer solstice of 14 hours 32 minutes. Long, but not Scandinavian. Compare it with Sapporo (roughly 43° N, about 15.5 hours) or Naha (roughly 26° N, about 13.5 hours). The winter solstice delivers 9 hours 47 minutes. Short, but not a polar night.
If you arrive from a tropical latitude, the winter days will feel clipped. If you come from northern Europe, the summer nights will feel surprisingly long.
Solar noon and the equation of time
Solar noon in Nagoya averages 11:48 JST. That is twelve minutes before the clock says noon. The offset exists because Nagoya lies west of the 135° E meridian, the reference line for Japan Standard Time. That meridian runs through Akashi, in Hyōgo Prefecture.
The equation of time adds another wobble. Earth’s elliptical orbit and axial tilt make solar noon drift by about ±15 minutes over the year. In early November it can push as late as 11:55. In mid-February it can pull as early as 11:42. That asymmetry is why sunrise and sunset do not shift in lockstep.
For most planning, 11:48 is a solid average. For solar panel alignment or sundial calibration, pull the daily figure from the tool on the page.
