Top Oiso Hotel Reviews

Hakone Kowakien TEN-YU

10/10 Excellent

"The room was traditional and fitted the location really well with all the amenities you need. Excellent shower. Breakfast is amazing so much choice. Staff very welcoming. Was fortunate enough to have an upgrade dinner with a Japanese tasting menu very very good."

The Prince Hakone Lake Ashinoko

8/10 Good

"Loved the room, very spacious. We had a little balcony. Refa blow dryer was a great surprise. Also, drinks in the fridge we're free. Sauna was great as well. Views of Mt. Fuji were unbeatable. The only downside is the food. We dined at the Japanese restaurant and we didn't enjoy the food for the price. We dined at the buffet and felt the same. Hakone is a small town and most of the restaurants close around 3pm so you rely on your hotel for dinner. Which is a shame because we loved everything else."
