Note: unlike most reviews on this site, this guide to Yunosato Okada is based on official sources and verified reviews rather than a personal visit — consistent with the research approach described on our About page. We’re including it because it offers something almost no other Hakone-Yumoto day-use facility does — early-morning bathing — and it’s worth knowing about alongside places like Hakone Yuryo.
Quick answer: want a genuine multi-source onsen on the hillside above Hakone-Yumoto, with the rare option to bathe from 6am before most other facilities even open? Yunosato Okada is one of the few day-use spots built for that. One important caveat before you plan around it: unlike Hakone Yuryo, this facility does not admit guests with visible tattoos.
Five Natural Springs on the Yusaka-yama Hillside
Yunosato Okada, run by the operators of Hotel Okada, draws on five of its own hot spring sources and sits partway up Yusaka-yama, the wooded hill above Hakone-Yumoto. The open-air bath looks out over the mountains, and the facility describes it as a good spot to catch moonrise on a clear evening — a quieter, more nature-facing setting than some of the larger resort-style day-use facilities closer to the station.
Early-Morning Bathing — A Genuine Rarity
This is the facility’s standout feature: Yunosato Okada offers early-morning bathing from 6:00 to 9:00 (around ¥1,000 for adults, with towel rental included), well before its regular 11:00 opening. Almost no other Hakone-Yumoto day-use onsen offers this. If you’re arriving in Hakone on an early train and want to soak before check-in time anywhere else, or you just prefer bathing before the day gets busy, this is a genuinely useful option that’s hard to find elsewhere in the area.
Sauna and Relaxation
Both the men’s and women’s baths have an auto-loyly sauna that releases a burst of steam roughly every 30 minutes, available from noon to 10pm. The rest area also has ten free massage chairs, and there’s a manga corner if you’re waiting on a companion.
Family Baths and Private Room Plans
For groups that want privacy, Yunosato Okada has a family bath (kazoku-buro) sized for one household group, plus set-course plans that pair a private tatami room with a meal and yukata rental — useful if you want to turn the visit into a longer, more relaxed stay rather than a quick soak.
Food
The on-site restaurant, Yamabiko, serves a mix of lighter options like soba alongside heartier dishes such as wagyu steak rice bowls and seafood rice bowls, with mountain views from the dining room. Meal-only visits are also welcome without booking the bath.
Hours and Admission
As of this writing, regular hours run 11:00–23:00 (last entry 22:00), with adult admission around ¥1,650 and elementary-age children around ¥800 (younger children free). Towel rental is roughly ¥300, with yukata rental around ¥500. Treat these figures as approximate and check the official site before you go, since day-use facilities periodically adjust rates and occasionally close for maintenance.
Access
Yunosato Okada runs a shuttle bus between Hakone-Yumoto Station and the Hotel Okada entrance, though the schedule varies by day — check the current timetable before you go. It’s also reachable by local bus from the station in around 7 minutes plus a short walk.
Onsen Etiquette — and an Important Tattoo Note
As with any Japanese public bath, shower and rinse thoroughly before entering the shared water. One point that matters more here than at many facilities: Yunosato Okada explicitly does not admit guests with tattoos, including temporary or sticker-style tattoos. If that’s a concern for you or anyone in your group, Hakone Yuryo, also near Hakone-Yumoto, has explicitly dropped its tattoo restrictions and is a more suitable choice.
Frequently Asked Questions

Can I visit just for the food?
Yes, the on-site restaurant welcomes meal-only visits without booking the bath.
Is there a way to get more privacy than the shared baths?
Yes — the facility has a family bath and set-course plans that include a private tatami room.

Who Yunosato Okada Is For
This is worth considering if you want a genuine multi-source onsen away from the busiest part of Hakone-Yumoto, if early-morning bathing fits your itinerary, or if a private family bath and a proper sit-down meal matter more to you than a large-scale resort-style facility — provided tattoos aren’t a factor for your group.
