When the weather turns in Hakone
Rain removes the whole point of the ropeway and the lake, because Fuji vanishes and Ōwakudani closes in bad weather regardless. Pivot indoors instead: the Pola Museum, the Okada Museum and the Open-Air Museum's indoor pavilions all hold up wet. Better still, stop travelling and use the water — Yunessun at Kowakidani has covered baths, and Tenzan's rock pools near Yumoto are partly roofed.
Hakone's museums, and which one to pick
The Hakone Open-Air Museum has been arranging sculpture across a hillside since 1969 and opens nine to five daily; its Picasso Pavilion holds several hundred works and its stained-glass tower is something children climb inside. The Pola Museum of Art is buried in beech forest to protect the view and is strong on French Impressionism. The Okada Museum and the Hakone Museum of Art's moss garden are the quieter pair.
What to eat in Hakone
Ōwakudani's kuro-tamago are eggs boiled in sulphur springs until the shells blacken, sold five to a bag with the claim that each adds seven years to your life. Down in Hakone-Yumoto the main street sells onsen manju steamed buns and Kanagawa soba. Kaiseki dinners come attached to the ryokan rather than sold separately. Wakasagi smelt from Lake Ashi and Gotemba beer are the lakeside plates.
What first-timers get wrong in Hakone
Ōwakudani shuts without notice when volcanic gas readings rise, and the ropeway then runs a replacement bus, so check status the morning you go rather than the night before. The Hakone Free Pass covers eight modes of transport but not the Romancecar, which needs a separate reserved-seat charge. Run the circuit anticlockwise from Hakone-Yumoto to stay ahead of the Odawara coach crowds. Tattoos still bar entry at many public onsen.
What things cost in Hakone
The Hakone Free Pass from Shinjuku is ¥7,100 for two days after the October 2025 increase, with a cheaper version sold from Odawara, and it repays itself if you complete the loop once. A Romancecar reserved seat adds roughly ¥1,200 each way. Open-Air Museum entry is about ¥2,000 and five black eggs at Ōwakudani cost ¥500. A ryokan with two meals starts near ¥20,000 per person.
