Sunlight Calculation (Select Location)
This tool examines the impact of buildings to the south on sunlight hours at your home in various regions of Japan.

Assume that the distance to the building is measured in a true south direction from your home, that the building is the same height as the entered value, and that it extends infinitely in the east-west direction.
Sunlight exposure from 3 a.m. to 9 p.m. will be examined at intervals of 15 minutes.
The compass directions are: North at 0 degrees, East at 90 degrees, South at 180 degrees, and West at 270 degrees.
