“Diamond Fuji” is one of the most iconic scenes in Japanese landscape photography.
It occurs when the sun aligns perfectly with the summit of Mount Fuji during sunset or sunrise.
This moment is brief, rare, and requires precise planning.
🌅 What is Diamond Fuji?
Diamond Fuji refers to the phenomenon where the sun sits exactly on top of Mount Fuji, creating a dazzling visual effect.
It typically happens:
- During winter seasons
- At specific viewing locations
- Under clear weather conditions
❗ Why is it difficult?
Capturing this moment depends on multiple variables:
- Date (solar trajectory changes daily)
- Observer location
- Viewing angle
- Earth’s axial tilt
Even a small positional difference can cause the sun to miss the summit.
🧠 How does prediction work?
To determine alignment, we calculate:
- Solar azimuth
- Solar altitude
- Direction of Mount Fuji from the observer
Alignment occurs when these match.
