Fuji-Hakone-Izu National Park is one of Japan’s best-known natural areas, located on the island of Honshu. It includes the region around Mount Fuji, the volcanic landscapes of Hakone, the Izu Peninsula and numerous offshore islands. Established in 1936, the park offers a remarkable variety of scenery, from mountain peaks and crater lakes to hot springs, forests and coastal landscapes.
Mount Fuji, Japan’s highest peak at 3,776 metres, is the park’s most recognisable landmark. Its nearly symmetrical volcanic cone has become one of the country’s defining symbols. On clear days, the mountain can be seen from viewpoints, lakeside areas and parts of the coast. Its silhouette is particularly striking at sunrise and during colder months, when the summit is covered in snow.
Mount Fuji and the lakes
The northern part of the park is known for the landscapes surrounding Mount Fuji. Several lakes in the area were shaped by volcanic activity and changes in the terrain. One of the best-known is Lake Ashi in the Hakone region. In favourable weather, mountains are reflected in its calm waters, while traditional shrines and walking routes can be found along the shore.
The area around Fuji is suitable for hiking, photography and discovering Japan’s volcanic landscapes. Depending on the season, the slopes feature spring blossoms, summer greenery or autumn foliage. Many visitors are especially drawn to views of the mountain framed by lakes and forests.
Hakone and hot springs
Hakone is known for its volcanic valleys, mountain scenery and hot springs, called onsen in Japanese. One of its best-known sights is Owakudani, a geothermal valley with steam vents, sulphurous springs and distinctive volcanic slopes. Visitors can observe signs of geothermal activity, although access to some areas may be restricted because of volcanic hazards.
Hakone also attracts visitors with its museums, art galleries, cable cars and walking routes around Lake Ashi. After exploring the natural attractions, travellers can relax at a traditional Japanese inn with hot springs and sample local dishes.
The Izu Peninsula and the coast
The southern part of the national park includes the Izu Peninsula, known for steep cliffs, beaches, waterfalls, wooded hills and coastal hot springs. The coastline features both sheltered bays and exposed stretches where powerful ocean waves meet the shore. Walking trails follow parts of the coast, offering views of the sea and unusual volcanic formations.
The region has waterfalls, coastal rock formations and small resort towns. The peninsula is suitable for walks, swimming in designated areas, sampling local cuisine and relaxing in onsen. Fresh seafood is a regional speciality in the coastal communities of Izu.
Plants and wildlife
The park’s range of elevations, climates and natural conditions supports a variety of ecosystems. These include temperate forests, mountain vegetation, volcanic terrain and coastal habitats. The climate on the Izu Peninsula is milder than in the highlands, so its plant communities differ noticeably from those on the slopes of Mount Fuji.
Different bird and mammal species inhabit the forests and coast, while the surrounding seas support a variety of fish and other marine animals. When visiting natural areas, stay on permitted trails, take rubbish with you and avoid disturbing wildlife.
When to visit
Fuji-Hakone-Izu National Park offers something in every season. Spring brings flowering trees and fresh greenery, summer is suitable for mountain trails and coastal exploration, autumn features colourful foliage, and winter can offer clear views of snow-covered Mount Fuji. Conditions vary considerably across the park because of differences in elevation and proximity to the ocean.
Before travelling, check the weather forecast, visibility of Mount Fuji and the current status of trails. Volcanic activity can lead to temporary restrictions around Owakudani and on some mountain paths. If you plan to visit hot springs or follow nature trails, check seasonal opening conditions and access rules in advance.
How to get to Fuji-Hakone-Izu National Park
The park covers a large area, so the best route depends on which section you plan to visit. Hakone can be reached from Tokyo by train with a transfer or by bus. Rail and bus services connect visitors with the Mount Fuji area, while trains and buses from major regional cities serve the Izu Peninsula. A car offers more flexibility in some areas, especially for reaching remote viewpoints and coastal trails.
To explore the park comfortably, choose one or two areas and allow enough time for each. The combination of Mount Fuji, Hakone’s volcanic landscapes, hot springs and the Pacific coast makes this one of Japan’s most diverse destinations for nature lovers.
