Highly recommended! I've been to more than 500 onsen in my 31+ years in Japan and it's one of the best! Try the salt before the cave for a great sweat. Their raw cotton towels are awesome too!
Lost count of he number of times I've been here but at least 30. Pure onsen water, relaxed atmosphere, places to nap, private rooms, delicious and reasonable restaurants. My #1 Tokyo getaway.
Very nice local onsen, with a good outdoor area with 6 different baths, 5 are outdoors and a sauna. You can also pay a bit extra for other services in the onsen. Lovely area, would recommend!
Awesome onsen. Beautiful location. The onsen itself is large and mostly open air, so the ambiance is outstanding if the weather is cold. One of the best onsens I have been to in Japan.
An excellent finish for a long day at Hakone: spacious outdoors onsen, great dining room with a few vegetarian options. Make sure to be courteous with the occasional tattooed visitors.
I don't understand all the good reviews here. The onsen is average at best. Pubic hair floating all over the water and the overall appearance is grimy.
