Hakone (箱根)

Hakone is a mountainous region in western Kanagawa Prefecture, positioned between the coastal city of Odawara and the hot spring town of Atami along the corridor connecting Tokyo with the Mount Fuji region. The area sits within the Fuji-Hakone-Izu National Park and occupies a volcanic basin formed by ancient eruptions. Today the landscape is defined by forested ridgelines, geothermal valleys, and Lake Ashi at the center of the caldera.

The terrain rises quickly west of Odawara, where coastal rail lines give way to mountain transport routes leading into the Hakone basin. From this transition point, the region spreads across several small towns that form the wider Hakone area, including Hakone-Yumoto, Tonosawa, Miyanoshita, Gora, Sengokuhara, Motohakone, and the Lake Ashi shoreline settlements.

Each of these towns developed around hot springs, mountain access points, or transport junctions that connect different parts of the basin. Hakone-Yumoto serves as the primary rail gateway into the mountains. Miyanoshita and Gora sit higher in the basin along the mountain railway route, while Sengokuhara spreads across a broader highland plateau near the northern side of the caldera. Motohakone and the lakeshore communities sit along the southern edge of Lake Ashi.

Several major landmarks structure movement across Hakone. Lake Ashi occupies the center of the region, surrounded by forested mountains and lakeside viewpoints. The Hakone Ropeway crosses the volcanic highlands above Owakudani, where geothermal steam vents mark the active volcanic zone. Along the lake’s edge stands Hakone Shrine, positioned within a cedar forest near the water.

Hakone also contains cultural sites such as the Hakone Open-Air Museum, located near the Gora area along the mountain railway route. Surrounding peaks form the rim of the caldera, including Mount Komagatake and Mount Kamiyama, which rise above the lake and geothermal valley.

Although Hakone functions as a contained mountain basin, nearby areas extend the landscape further. Odawara marks the eastern gateway where coastal rail routes meet the mountain transport network. To the north in the Ashigara hills stands Daiyuzan Saijoji Temple, located in a forested valley outside the Hakone basin but within the broader western Kanagawa mountain system.

Hakone sits at the eastern edge of the volcanic terrain that continues toward the Izu Peninsula and the Mount Fuji region. Its caldera basin, mountain towns, and interconnected transport routes make it one of the most geographically distinctive areas within Kanagawa Prefecture.
