Hakone Kowakien Yunessun, Hakone-machi

The place offers both nude and costume hot spring. The nude section is different and offers just bath. However the costume section offers jacuzzi, coffee, wine, green tea and similar other hot baths. Their is rain and some slides as well. The place is really nice, just make sure that you have only till 7 pm. I have given lower rating because they advertise the place remains open till 8 pm and still they locked half of the place at 7 pm since there weren't too many tourist. Had a bad experience in this sense.

If you’re looking for an onsen experience, do not make the same mistake we did and visit this place. This “onsen” is a run down, dirty (think mold, discolored water), and all-around pig sty of a water park. The baths aren’t hot and I can guarantee it isn’t spring fed. The buffet is marginal and costs 2500 yen per person. You’ll leave smelling of chlorine and fully dissatisfied. Please go somewhere else.

Yunessun is a super fun day out. Heading there with friends can be a really relaxing experience, as you take your time to go through the themed baths, saunas, and even doctor Fish (those little fish that eat the dead skin off of your feet). The themes for the bath are really fun, and I recommend that you wait for them to refill them (the staff will very gladly poor coffee directly on you) and don't worry about your swimwear, everything is diluted enough to not cause stains.

Came for the onsen here. Was a good value with the discount tickets from the train stations, having both a discount and free swimwear and towels. The pools are novelties, but aren't really very warm. The outdoor area has a fun slide though.

Fun for one day to try. Everyone loved the fish pedicure thing. Don’t forget to walk outside further down the path. There’s another set of pools with a beautiful view of the mountainside. Food was pricey and mediocre. Quality of massages were not equal to price. So don’t bother. Some parts of the pools were run down. Peeling paint and so on. Recommend this for one time visit. We do not plan on revisiting.
