Pack a few snacks and enjoy a relaxing family day out at Onshi Hakone Koen Park. There's plenty of space for the kids to run around and get some fresh air.

Onshi Hakone Koen Park is an ideal place to begin your day of discovery in Hakone. This outdoor recreational space is recommended by fellow travelers, but it isn't the only spot to see here. Pencil in time for other sights like Lake Ashi, Hakone Kowakien Yunessun, and Hakone Shrine to really experience what the area has to offer.

The general condition of the room is awesome. The smell of the towels provided was not ideal. Washing machine is not ideal especially during the drying part as the dryer does not dry our clothes effectively. Probably need to have a separate dryer instead.
