What actually matters for a Hakone trip
- A compact umbrella — Hakone's mountain microclimate ignores the Tokyo forecast more often than you'd think
- Motion sickness tablets — the Tozan bus switchbacks and the Owakudani ropeway catch people who never get sick anywhere else
- A small zip pouch for valuables — day-use onsen changing rooms don't always have lockers
- A compact power bank — Lake Ashi photos plus offline maps drain a phone faster than most single-day trips
- Layers, not a heavy coat — Hakone runs several degrees cooler than central Tokyo year-round
What you don't need to pack: yukata, slippers, bath towels, and basic toiletries — every ryokan and most day-use baths provide these.
Hakone gets sold as the simplest day trip from Tokyo: one Romancecar, one loop, one onsen, done. The trip itself is simple. What catches people off guard is that Hakone behaves like three different places layered on top of each other — a mountain resort with its own weather, a historic onsen town with its own etiquette, and a transit system with more ropeway and switchback-road sections than any other day trip near Tokyo. None of that requires a bigger suitcase. It requires packing a handful of specific, small things that a generic "Japan trip" packing list won't mention.
This guide covers exactly that: what a Hakone ryokan or day-use onsen already has waiting for you, what the mountain weather and transit actually demand, and what's genuinely optional. If you also need the itinerary itself, see our Hakone in a Day guide for the Free Pass routing and loop order.
Why trust this guide
We live in Tokyo and run the Hakone loop on average once a season, in every weather condition from clear winter mornings to the kind of August humidity that fogs up a camera lens. Every item on this list earned its place because we either forgot it once and regretted it, or watched a travel companion struggle without it. This is not a generic "Japan packing list" with Hakone's name swapped in — it is specific to the mountain road, the microclimate, and the ryokan culture that makes Hakone different from a flat-ground day trip like Kamakura or Yokohama.
What the ryokan already provides
Start by subtracting, not adding. Almost every ryokan and hot-spring hotel in Hakone provides the following as standard, so there is no need to pack your own:
- Yukata (cotton robe) — sized for the room, worn to dinner, the bath, and around the inn
- Room slippers — for use inside your own room and the corridors leading to it
- Bath towels and a small hand towel — for use at the room's or the inn's onsen
- Basic toiletries — shampoo, body soap, and often a razor and toothbrush set, though quality varies by property
What ryokans do not reliably provide: a quick-dry towel that won't still be damp the next morning, slip-resistant sandals for the stone paths between your room and an outdoor bath, or anything for a day-use onsen visit where you are not staying overnight. That gap is where most of this list lives.
Onsen etiquette items worth packing
A compact, zip-top pouch for valuables
If you are doing a day-use onsen (visiting a hot spring without staying the night — extremely common in Hakone), changing rooms do not always have lockers. Leaving a phone and wallet loose on a shelf while you soak is the single most common small regret we hear about. A small waterproof zip pouch that folds flat solves this without adding real weight to a day bag.
Non-slip sandals for inn and onsen-town walking
Stone paths between a ryokan room and its outdoor bath, and the cobbled streets of Hakone-Yumoto and Gora, get slick when wet. Your own slip-resistant sandals are more reliable than whatever indoor slippers the inn provides, especially outdoors.
A tattoo-cover sticker, if it matters to you
Policy on visible tattoos still varies by property in Hakone — some traditional communal baths restrict them, others are relaxed, and a growing number sell cover stickers at reception. If this is a concern, the cleanest solution is booking a ryokan with a private in-room or private-rental (kashikiri) bath, which sidesteps the issue entirely. We cover five such properties in our guide to Hakone ryokans with a private onsen.
Skip the fragrance
Scented lotions, perfume, and strongly fragranced shampoo are discouraged at shared onsen facilities out of consideration for other bathers. If your travel toiletries are heavily scented, a small fragrance-free set for the bath itself is worth packing separately.
This guide took real days of walking, asking, and double-checking — not a weekend of copy-pasting other blogs. If it saved you from a bad booking or a wasted afternoon, a coffee tells us it mattered.
Buy us a coffee →Mountain weather — layers and rain
Hakone sits at elevation with its own microclimate, and the gap between a Tokyo forecast and the reality in Gora or around Owakudani catches first-timers constantly. We have left Shinjuku under a clear sky and arrived at Owakudani in drifting mist within 90 minutes.
- Pack a compact umbrella even on a "clear" forecast day — mountain weather changes faster than the app updates
- Think layers, not one heavy coat — Hakone runs several degrees cooler than central Tokyo year-round, and temperature swings between the valley floor and Owakudani's higher elevation
- A light rain shell beats a poncho for the ropeway — you'll have both hands occupied with a phone or camera at the viewpoints, and a shell that packs small is easier to stow between stops than a bulky poncho
If rain is already forecast above 30%, or the word "mist" shows up for the Owakudani area specifically, check the ropeway's operational status before you leave the hotel — strong wind or volcanic gas readings occasionally pause that section, and knowing in advance saves a wasted detour.
Motion sickness on the bus and ropeway
This is the item most packing lists skip entirely, and the one we get asked about the most. The Hakone Tozan bus climbs a genuinely switchback-heavy mountain road, and the ropeway crossing over Owakudani has a noticeable sway at the mid-span towers. Both are known soft spots even for travelers who rarely feel motion sickness on flat ground or regular trains.
Most over-the-counter motion sickness tablets work best when taken 30 to 60 minutes before departure — which in practice means taking one before boarding the Romancecar in Shinjuku, not after you already feel queasy on the mountain bus. If you are traveling with someone who gets carsick easily, this single five-minute step before leaving Tokyo prevents the most common reason a Hakone day gets cut short.
Battery, maps, and connectivity
Between offline maps for the ropeway and boat schedules, transit apps for the mountain train and bus connections, and photos at Lake Ashi and Owakudani, a full Hakone day drains a phone faster than most single-day itineraries in Japan. We have watched a fully-charged phone drop under 20% by mid-afternoon on a photo-heavy loop.
- A compact 5,000mAh power bank covers roughly one extra full charge — enough for most single-day loops
- Download offline maps before you leave Tokyo — signal gets patchy in the Owakudani valley and on sections of the ropeway
- Screenshot your Free Pass QR code or ticket as a backup in case of a dead-zone moment right when a gate scanner needs it
Where to Eat — Locally Well-Regarded Spots
This isn't a packing item, but it comes up often enough in the same breath as "what should I bring" that it's worth a short detour. None of these are affiliate bookings — just places that come up repeatedly in Hakone recommendations and are commonly suggested to first-time visitors.
Amazake-chaya (甘酒茶屋)
A teahouse on the old Tokaido road between Hakone-Yumoto and Moto-Hakone that has been serving amazake (a sweet, lightly fermented rice drink) and grilled chikara-mochi for generations. It's commonly recommended as a rest stop on the old post-road walk, and it's one of the few roadside teahouses in the area still operating in something close to its original form.
If that stop turns into one of your favorite five minutes in Hakone, a coffee tells us it was worth including.
Buy us a coffee →Hatsuhana (はつ花) soba
A long-running soba restaurant in Hakone-Yumoto, frequently named in round-ups of the area's best soba, known for a yama-imo (mountain yam) broth poured over handmade noodles. It's close enough to the station to work as a stop right before or after the loop.
If this saved you from guessing at a menu with no English, a coffee helps us keep finding ones like it.
Buy us a coffee →Fujiya Hotel dining room
Open since 1878 in Miyanoshita, the Fujiya Hotel's classic Western-influenced "yoshoku" dishes — its curry especially — are commonly recommended even to travelers who aren't staying there. The dining room takes walk-in lunch guests alongside hotel guests.
If a plate of that curry made the trip a little better, a coffee is how you'd tell us.
Buy us a coffee →Owakudani's kuro-tamago (black eggs)
At the Owakudani ropeway station, eggs boiled in the sulfurous hot-spring water turn black and are sold as a well-known local snack — commonly recommended as a quick bite between ropeway connections (local legend says each egg adds years to your life).
If this tip stopped you from walking right past them, a coffee lets us know it landed.
Buy us a coffee →Day trip vs. overnight packing
Not every item on this list earns equal priority depending on how you're visiting.
- Day trip, no overnight stay: prioritize the umbrella, motion sickness tablets, power bank, and the valuables pouch if you're doing a day-use onsen. Skip the quick-dry towel and non-slip sandals unless you know you'll be bathing more than once.
- One night at a ryokan: add a quick-dry towel (ryokan towels can run thin) and your own slip-resistant sandals for the walk between room and bath. Everything else — yukata, slippers, basic toiletries — is provided.
- Visiting in winter: layers matter more than any single item. The gap between a sunny Tokyo afternoon and a genuinely cold Hakone evening is bigger than most first-time visitors expect.
Traveling with kids
Hakone is very workable with children, but three small additions make the day noticeably smoother. A tablet or phone holder that clips to the Romancecar's seat-back tray (where permitted) or a car seat headrest turns the 85-minute ride from a restlessness problem into a non-issue. Travel-size antibacterial wipes are worth having on hand for the inevitable hands-on moments around Owakudani's black eggs and Hakone-Yumoto's street food. And if your child gets excited about a yukata for the ryokan evening, most inns can arrange a kids' size on request — worth asking when you book rather than assuming.
FAQ
Do ryokans in Hakone provide towels and yukata?
Yes, almost every ryokan and hotel provides a yukata, room slippers, and bath towels as standard. What they often do not provide is a quick-dry towel for the trip there and back, or non-slip sandals for walking the stone paths between the room and the outdoor bath.
Is Hakone's weather different from Tokyo's?
Often, yes. Hakone sits at elevation with its own microclimate, so a sunny Tokyo forecast does not guarantee the same in Gora or around Owakudani. Mist, light rain, and stronger wind are common even when Shinjuku is clear, so a compact umbrella is worth packing even on a forecast-clear day.
Do I need motion sickness tablets for Hakone?
If you are prone to motion sickness at all, yes. The Hakone Tozan bus climbs a switchback mountain road and the ropeway over Owakudani has noticeable sway — both are common triggers even for people who rarely feel sick on transport. Most tablets work best taken 30–60 minutes before departure, so take them before boarding the Romancecar in Shinjuku, not after you already feel queasy.
Can I bring my tattoos to a Hakone onsen?
Policy varies by property. Some traditional communal baths still restrict visible tattoos, while others are tattoo-friendly or offer tattoo-cover stickers at reception. If a private in-room or private-rental (kashikiri) onsen matters to you, booking a ryokan with one removes the issue entirely — see our separate guide to Hakone ryokans with private onsen.
How much battery will I actually use in Hakone in one day?
More than you expect. Between offline maps, transit apps for the ropeway and pirate ship schedules, and photos at Lake Ashi and Owakudani, a full day easily drains a phone from 100% to under 20% by early evening. A compact 5,000mAh power bank covers roughly one extra full charge, which is enough for most single-day itineraries.
