Hakone is Japan’s most accessible and popular onsen resort destination — 90 minutes from Tokyo by Romance Car express train, yet feeling entirely worlds apart. The mountainous area straddles Kanagawa and Shizuoka prefectures around Lake Ashi, with over 20 distinct onsen source areas, a remarkable arts scene anchored by the Open Air Museum, and on clear days a direct view of Mount Fuji that justifies every photograph ever taken of it. Hakone rewards both day-trippers and overnight guests, though a ryokan stay transforms the experience.
Getting There & the Hakone Freepass
The Romancecar express from Shinjuku to Hakone-Yumoto takes 85 minutes and costs ¥2,470 (reserved seating required, reservable via Odakyu app or station machines). The Hakone Freepass (¥6,100 from Shinjuku, 2 days) covers the Romancecar fare plus unlimited rides on the Hakone Tozan Railway, Hakone Ropeway, Hakone Cruise boat on Lake Ashi, and multiple bus routes — the most cost-effective way to explore the full area. JR Pass holders: the Odakyu line is not covered by the JR Pass.
Onsen in Hakone
Hakone has over 20 onsen source areas (gensen), each with different water chemistry and color. The main resort cluster at Hakone-Yumoto has public bathhouses (soto-yu) open to non-guests for ¥500–¥1,500. Tonosawa and Miyanoshita onsen areas feature historic ryokan that have operated for over a century. The sulfurous Owakudani volcanic area produces distinctive black eggs (kuro-tamago) — hard-boiled in the hot springs and said to extend life by seven years. Day-use plans (higaeri nyuyoku) at most ryokan allow access to baths and sometimes meals without overnight stay.
Mount Fuji Views
The classic Hakone Fuji view is from the Lake Ashi shoreline or cruise boat, with the volcano reflected in the lake’s surface. The Hakone Ropeway between Sounzan and Togendai offers aerial views over Owakudani’s steam vents toward Fuji when clear. The best viewing months are November–March when the air is dry and clear; summer sees frequent cloud cover. Sunrise views from ryokan facing west are the most spectacular but require the luck of clear weather — confirm conditions via the Hakone webcam before booking.
Hakone Open Air Museum
The Hakone Open Air Museum (Hakone Chokoku no Mori) is Japan’s first outdoor sculpture museum, established in 1969 across 70,000 square meters of landscaped grounds. Permanent collections include a dedicated Picasso pavilion (over 300 works), significant pieces by Rodin, Henry Moore, and Miro, and rotating contemporary installations. The Foot Bath area within the museum allows visitors to soak in onsen water while viewing sculptures — a uniquely Japanese hybrid experience. Admission ¥1,600; included in some Hakone Freepass versions.
Ryokan Recommendations
Hakone has some of Japan’s finest ryokan, from traditional wooden inns to contemporary design properties. Key tiers: luxury (Gora Kadan, Hyatt Regency Hakone), mid-range (Hakone Ginyu, Yama no Chaya), and accessible (numerous Hakone-Yumoto properties). All traditional ryokan include kaiseki dinner and breakfast in the rate. Rates range from ¥15,000–¥80,000+ per person including meals. Book at least 2–3 months ahead for weekends; last-minute weekday availability is sometimes possible.
Practical Tips
- Day-trip vs. overnight: A day trip covers the Open Air Museum and lake cruise adequately; an overnight ryokan stay adds the onsen, kaiseki dinner, and morning mountain atmosphere
- Crowds: Hakone is extremely busy on weekends and holidays year-round; weekday visits are noticeably more relaxed
- Weather: The Owakudani ropeway closes in strong wind or volcanic activity — check before relying on it for transport
- Tatami rooms: Request a mountain-view or garden-view room when booking ryokan; standard rooms face interior corridors
- Coin locker tip: Store main luggage at Odawara Station and travel to Hakone light; Odawara has large lockers near the Romancecar platform
