Hakone is one of the most popular day trips from Tokyo — a volcanic valley with hot springs, a famous loop course of scenic transport, and (on good days) Mt. Fuji views. This guide covers how to do it in one day, what it typically costs, and what to realistically expect.
箱根は東京からの日帰り旅行で最も人気のある目的地のひとつ。温泉・ロープウェー・芦ノ湖の海賊船を1日で巡るループコースと、費用・注意点をまとめました。
01Getting there
All routes start from Shinjuku Station in Tokyo. You have two main options to reach Hakone-Yumoto, the gateway station to the Hakone area.
すべてのルートは新宿駅から。箱根の玄関口・箱根湯本駅までの行き方は主に2通り。
Romancecar (recommended)
The Odakyu Romancecar is a limited express with reserved seats, large windows, and a smooth ride. It runs directly from Shinjuku to Hakone-Yumoto in about 85 minutes. The cost is ¥2,330 one-way (base fare ¥1,220 + reserved seat supplement ¥1,110). Book seats in advance at Odakyu counters or the e-Romancecar website — window seats on the left side offer the best views.
Regular Odakyu express (budget option)
The standard Odakyu Line express takes about 2 hours from Shinjuku to Hakone-Yumoto with a transfer at Odawara. The fare is approximately ¥900 one-way. No reservation needed — just tap your IC card. This is the budget option but the seats are standard commuter-train style.
Hakone Free Pass
The Hakone Free Pass (¥6,100 from Shinjuku, ¥4,600 from Odawara) is the key to a Hakone day trip. It covers the round-trip Odakyu train fare plus unlimited use of all loop course transport: Hakone Tozan Railway, cable car, ropeway, pirate ship, and Hakone Tozan Bus. It does not include the Romancecar supplement (¥1,110 each way) — that's extra.
箱根フリーパス（新宿発¥6,100）はループコースの全交通機関が乗り放題。ロマンスカー特急券（片道¥1,110）は別途必要。
Buy the Hakone Free Pass. Take the Romancecar at least one way (outbound morning is best — you arrive fresh and save time). The pass pays for itself in a single loop.
02The Hakone Loop Course
The "Hakone Loop Course" is the classic circuit that takes you through the entire Hakone area using a series of different transport modes. It's genuinely fun — each leg feels different, and the variety keeps things interesting all day.
箱根ゴールデンコースは、異なる乗り物を乗り継いで箱根を一周する定番ルート。乗り物好きなら間違いなく楽しい。
Leg 1: Hakone Tozan Railway (~40 min)
From Hakone-Yumoto to Gora. This is Japan's oldest mountain railway, climbing through steep switchbacks where the train literally reverses direction three times. The zigzag ascent through forested mountainside is one of Hakone's signature experiences. Sit on the right side for the best views.
Leg 2: Cable Car (~10 min)
From Gora to Sounzan. A steep funicular that climbs the final stretch of mountain. Short but scenic. The Hakone Open-Air Museum is a worthwhile stop near Gora if you have extra time (separate admission ¥1,600).
Leg 3: Ropeway over Owakudani (~30 min)
From Sounzan to Togendai via Owakudani. This is the highlight of the loop — a gondola ride over volcanic steam vents with sulfur-yellow rocks and billowing white gas below. Stop at Owakudani station to see the vents up close and try the famous black eggs (kuro-tamago) boiled in volcanic hot springs. A bag of 5 costs ¥500. Legend says each one adds 7 years to your life.
大涌谷は箱根ループの最大の見どころ。火山性ガスで黒くなった名物「黒たまご」（5個¥500）は必食。
Leg 4: Pirate Ship on Lake Ashi (~30 min)
From Togendai to Hakone-machi or Moto-Hakone. These ornate pirate-themed ships cruise across Lake Ashi with Mt. Fuji as a backdrop (weather permitting). The ships are kitschy but the lake views are legitimately beautiful. On clear days, the Fuji reflection on the lake is stunning.
Leg 5: Bus back (~35 min)
From Hakone-machi or Moto-Hakone back to Hakone-Yumoto via Hakone Tozan Bus. This completes the loop. Along the way, you pass the famous Hakone Shrine torii gate on the lake — worth a quick stop if you get off early and walk.
The full loop takes approximately 5-6 hours including wait times and a stop at Owakudani. Start early to avoid rushing.
03Onsen experience
Hakone is one of Japan's premier onsen (hot spring) areas, and soaking in a natural hot spring is an essential part of the experience. Even on a day trip, you can enjoy day-use onsen at Hakone-Yumoto — do this after the loop course when your legs are tired.
箱根は日本有数の温泉地。日帰り入浴はループコースの後、箱根湯本で。疲れた体に最高です。
Recommended day-use onsen
Tenzan Tohji-kyo (天山湯治郷) — A popular outdoor onsen complex about 15 minutes by shuttle bus from Hakone-Yumoto station. Multiple outdoor baths in a natural forest setting. Day use around ¥1,300. Has a relaxed, authentic atmosphere.
Hakone Yuryo (箱根湯寮) — A modern facility with private open-air baths and a common area. Shuttle from Hakone-Yumoto station (3 minutes). Day use around ¥1,500-2,050. Clean, well-maintained, good for onsen beginners.
Most day-use onsen in Hakone-Yumoto cost between ¥1,500 and ¥3,000 depending on the facility and time of day.
Tattoo policies
This is important for international visitors: many traditional onsen in Japan do not allow tattoos. Hakone Yuryo generally permits small tattoos if covered with special tape (available at the front desk). Tenzan Tohji-kyo is more relaxed about tattoos. If you have visible tattoos, ask at reception before paying — staff are accustomed to the question. Private baths (kashikiri) are always an option regardless of tattoos, typically ¥3,000-5,000/hour.
タトゥーのある方は入浴前に受付で確認を。貸切風呂ならタトゥーの有無に関係なく利用可能。
Don't skip the onsen — it's what makes Hakone different from every other day trip. Even 60-90 minutes of soaking after the loop course transforms the entire day.
04Costs breakdown
Here's a realistic budget for a Hakone day trip from Tokyo. All prices are per person.
箱根日帰り旅行の現実的な予算。すべて1人あたりの金額。
| Item | Cost | Notes |
|---|---|---|
| Hakone Free Pass | ¥6,100 | From Shinjuku (or ¥4,600 from Odawara) |
| Romancecar supplement | ¥1,110 | Per direction — ¥2,220 for round trip |
| Lunch | ~¥1,500 | Soba, curry, or bento at Owakudani/Gora |
| Black eggs | ¥500 | 5 eggs at Owakudani |
| Day-use onsen | ¥1,500-3,000 | Tenzan or Hakone Yuryo |
| Total estimate | ¥9,000-12,000 | ~$60-80 USD |
Budget option: skip the Romancecar supplement (take regular express) and choose a cheaper onsen to bring the total down to around ¥8,000-9,000. The Hakone Free Pass is the one thing you shouldn't skip — buying individual tickets for the loop would cost significantly more.
05Mt. Fuji view reality
Let's be honest about this: Mt. Fuji is visible from Hakone roughly 40% of days. Clouds, haze, and humidity hide it more often than not. Many visitors do the entire loop course and never see Fuji at all.
箱根から富士山が見えるのは約4割の日だけ。雲や霞で見えないことの方が多い。富士山目的だけで箱根に行くのはリスクが高い。
Best chances for a clear view
Winter mornings (November-February) offer the best visibility — cold, dry air and clear skies. Early morning is always better than afternoon. After rain or strong wind, the air tends to be clearest. Summer is the worst season for Fuji visibility due to humidity and haze.
Check before you go
Search for "Hakone ropeway webcam" or "Owakudani live camera" before departing. Multiple webcams show real-time conditions. If Fuji is hidden at 7am, it's unlikely to appear later in the day.
Don't go to Hakone ONLY for Mt. Fuji views. Go for the loop course, the onsen, and the volcanic scenery. If Fuji appears, that's a bonus. If it doesn't, you'll still have a great day.
06Tips & warnings
Practical advice to make your Hakone day trip run smoothly.
箱根日帰りをスムーズにするための実践アドバイス。
Start early
Aim for the 7:00-8:00am Romancecar from Shinjuku. The loop takes 5-6 hours, and you want time for onsen before heading back. A 9:00am departure means you'll be rushing the second half of the day.
Ropeway closures
The Owakudani Ropeway closes in bad weather (strong wind, storms) and during periods of increased volcanic activity. This has happened multiple times in recent years. Check the Hakone Ropeway website on the morning of your trip. If the ropeway is closed, a substitute bus runs the route — functional but far less scenic.
Crowds
Weekends, especially in autumn (October-November) and Golden Week (late April-early May), are extremely crowded. Wait times for the ropeway can exceed 60 minutes. Weekdays are dramatically better. If you can only go on a weekend, start even earlier.
Consider staying overnight
If your budget allows, an overnight ryokan (traditional inn) stay transforms Hakone. You can do the loop at a relaxed pace, enjoy a private onsen in the evening, and have a kaiseki dinner. Ryokan start around ¥15,000/person with meals. Even a budget guesthouse removes all the time pressure.
What to bring
Comfortable walking shoes, a small towel for onsen (or buy one there for ¥200-300), layers for mountain weather (it's cooler than Tokyo year-round), and cash — some smaller onsen and food stalls don't accept cards.
歩きやすい靴、タオル（現地購入可）、山の気温に対応できる重ね着、現金（カード非対応の施設あり）を持参。
Hakone is worth the full day and the cost. The combination of scenic mountain transport, volcanic landscape, and a hot spring soak is unlike any other day trip from Tokyo. Just start early and don't pin all your hopes on Fuji.
