Common questions
What is Diamond Fuji?
The moment the sun rises or sets exactly over the summit, making the peak glow like a diamond. It only happens on a few days a year at each spot.
When is golden hour at Lake Kawaguchiko?
Roughly the first hour after sunrise and the last hour before sunset. Use the calculator above for the exact times on your date.
Why do the times differ from my weather app?
We calculate for the exact viewpoint, not the nearest city. Mountains on the horizon can delay the visible sunrise by a few minutes.
