Rising to 3,776 m (12,388 ft), Mount Fuji is Japan’s most iconic volcano. Its smooth cone looks different by season. The slopes can appear white because of snow, light-colored volcanic ash, and weathered rock.
In 2013, UNESCO listed Fujisan as “a sacred place and a source of artistic inspiration.” The World Heritage property includes the summit area and 25 cultural sites around the base, such as Sengen shrines, pilgrim lodgings, lakes, and lava-shaped landscapes.
Brief Timeline
| Year | Event |
|---|---|
| Jōmon–historic | Repeated eruptions lay down wide lava fields |
| AD 864–866 | Jōgan eruption: lava flows help form today’s Lakes Sai & Shōji. Aokigahara forest later grows on the flows. |
| AD 1707–1708 | Hōei eruption: a crater opens on the SE flank. Ash reaches Edo (about 100 km away). |
| 2013 | UNESCO listing as a cultural landscape (Criteria iii, vi) |
| 2024 | Yoshida Trail crowd controls begin (daily cap and night restrictions). A fee starts on the Yamanashi side. |
| 2025 | A ¥4,000 hiking fee applies on all trails. Rules are refined for safety and conservation. |

How Mount Fuji Became a World Heritage Landscape
| Era | From 12th-century mountain practice, through Edo-period Fuji-kō pilgrimages, to modern conservation |
|---|---|
| Patrons & Stewards | Sengen shrine networks, oshi (pilgrim guides), local governments, and Japan’s environment agencies |
| Place | Yamanashi & Shizuoka Prefectures, about 100 km southwest of Tokyo |
| People | Pilgrims and mountain practitioners; artists such as Hokusai & Hiroshige |
| Plan | Routes and rituals linked with lakes, springs, waterfalls, and volcanic features |
| “Construction” | Fuji formed naturally from lava, ash, and scoria. Later, people shaped the pilgrim routes, huts, and shrines. |
World Heritage Facts & Visitor Numbers

Materials
| Category | Mount Fuji | Notes |
|---|---|---|
| Main stone | Basalt | Basalt lava built the main cone |
| Secondary | Scoria, ash, lapilli, pumice | Layered volcanic deposits on the slopes |
| Core/Backing | Volcanic edifice | A natural mountain body, not a built core |
| Inlay / dark stone for script | — | Not applicable |
| Metals | — | Not applicable |
| Granite as primary material | Not used | Fuji is a basalt volcano, not a granite mountain |
Why Basalt, Not Granite?
Granite forms deep underground and cools very slowly. That is why it is strong and widely used in temples, gardens, and stone lanterns.
Mount Fuji is different. Fuji was built mainly by basalt lava that erupted at the surface and cooled quickly. Over time, ash, scoria, and weathering shaped the slopes.
The mountain can look white in some seasons. The main reasons are snow, light volcanic deposits, and sunlight on weathered rock. In other seasons, the darker basalt becomes more visible.
Legends — Myth vs Fact
| Theme | Myth & Faith | What the record shows |
|---|---|---|
| Deity | Asama no Ōkami resides at the summit | Summit shrines and ohachimeguri show long worship at the top |
| Purification | Water rites at lakes and springs | The Five Lakes and springs were used for cleansing before climbs |
| Artistic icon | Fuji as the perfect cone | Ukiyo-e by Hokusai and Hiroshige shaped how the world sees Fuji |
Care, Time, and the Color of Memory
Today, Fuji faces overtourism and safety risks. That is why authorities limit entry on busy routes and restrict late-night climbing. A ¥4,000 fee (from 2025) supports safer management and better conservation.
My Personal Pledge — Returning to the Summit
When I was about ten, I tried to climb Mount Fuji. But I had to turn back. The feeling stayed with me for years.
I want to finish what I started. I will climb Fuji again, take my own summit photos, and publish the story on this blog.
FAQ
- Is Fuji made of granite? No. It is mainly basalt, with layers of ash, scoria, and pumice.
- Why do Fuji’s slopes look white? Mostly snow, light ash, and weathered rock reflecting sunlight.
- Do I need to reserve? Online reservations are recommended on busy trails.
- What is the fee? ¥4,000 per person (all trails, per climb) during the season.
- Best timing? Early-season weekdays or quieter windows after Obon. Always check for closures.
