## Key Facts

- Mt. Fuji stands 3,776 meters tall, located roughly 100 kilometers from Tokyo.
- Fully visible on about 134 days per year on average, per Fuji City's 8 a.m. observations across 1991-2025 (4,684 of 12,784 observed days). Source: https://www.city.fuji.shizuoka.jp/documents/7545/fujisan-kiroku2025.pdf
- Best visibility: November through February (cold, dry Siberian air). Worst: June and July (rainy season) and humid summer months.
- Early morning is consistently the best time of day; clouds and haze build through the afternoon.

## Visibility Forecasting

The core feature provides 10-day visibility forecasts for Mt. Fuji from two viewing directions:

- **North side**: Views from Kawaguchiko, Yamanakako, and the Five Lakes region
- **South side**: Views from Hakone, Lake Ashi, Gotemba, and the Suruga Bay coastline

Each day is split into AM/PM periods because visibility conditions vary significantly:
- Morning often has clearer skies before afternoon cloud buildup
- Afternoon can bring thermal updrafts and haze, especially in summer

### Visibility Scoring System (1-10 scale)

| Score | Level | Meaning |
|-------|-------|---------|
| 8-10 | Visible | Clear, sharp views of the full mountain |
| 6-7 | Partially Visible | Recognizable but softened by haze or partly covered by clouds |
| 3-5 | Barely Visible | Only faint outlines or brief glimpses through gaps in clouds |
| 0-2 | Not Visible | Hidden behind clouds, rain, or thick haze |

Forecasts correlate with weather data including cloud cover percentage, precipitation probability, humidity, and wind conditions. The full methodology is documented at [/methodology](https://isfujivisible.com/methodology). Today's conditions and scores are available on the [homepage](https://isfujivisible.com/).

## Seasonal Maps

### Koyo (Autumn Colors) Map
Interactive prefecture-level map showing autumn foliage status across Japan. Available September 15 through December 15. Helps tourists time visits to see peak fall colors alongside Mt. Fuji.

Both maps feature date-based filtering to check historical and forecasted conditions for specific travel dates.
