Mount Fuji last erupted in 1707, and the ash fell on Edo — modern Tokyo — roughly 100 kilometres away. The Hōei eruption left a crater on the southeast flank that remains visible from the air today.
The mountain has been quiet ever since, but it is still classified as active, and the volcanic system that built it also built Hakone, the collapsed caldera to its southeast. Any mt fuji & hakone tour with bullet train travels, in effect, between two chapters of the same geological story.
Fuji is a stratovolcano of 3,776 metres, the tallest point in Japan, and a composite of three volcanoes stacked in sequence over hundreds of thousands of years. It was inscribed on the UNESCO World Heritage list in 2013 — not as a natural site, but as a cultural one. The listing recognises the mountain's role in Shinto and Buddhist practice, in the Fujikō pilgrimage confraternities of the Edo period, and in art. Hokusai's Thirty-six Views of Mount Fuji, printed in the 1830s, fixed the cone's silhouette in the global imagination before photography existed.
Hakone's history runs alongside it. The caldera formed some 40,000 years ago; Lake Ashi fills part of the crater floor, dammed by a landslide roughly 3,000 years old. Owakudani, the valley of sulphurous vents above the lake, still emits steam and hydrogen sulphide, and the black eggs boiled in its hot springs remain a local emblem. In the Edo period Hakone held one of the most important barrier stations on the Tōkaidō road between Kyoto and Edo, where travellers' papers were checked beneath cryptomeria avenues that still stand.
The railway changed everything. The Tōkaidō Shinkansen opened in 1964 and cut the journey along that same corridor to a matter of hours; Odawara Station, the gateway to Hakone, sits on the line. That is why a mt fuji & hakone tour with bullet train works as a single day rather than an overnight expedition. Access to the mountain itself runs up the Fuji Subaru Line to the 5th Station at 2,300 metres, above the tree line and below the summit. Hakone tours combining the ropeway and Lake Ashi cruise follow the caldera rim. Mount Fuji and Hakone sightseeing tours of this kind are less a route than a compression of geology, pilgrimage and engineering into one meridian of travel.
