Tokyo / Takao / Takao no Yu onsen
Near to Takao. This is a great onsen to go to after a hot day hiking around Mt. Takao. The indoor area is huge and I spent a long time relaxing in the various different pools. Take the shuttle bus from one of the bus stops outside the supermarket near the train station.
Kagawa / Naoshiima / Naoshima Sento
THis is not an onsen but a sento. But this is probably one of the most unique sento in the whole of Japan. The entire sento is an installation artwork by a famous Japanese contemporary artist Shinro Otake and there are many quirky artifacts inside the bath and the changing rooms. There is also a huge elephant above the pools. Best to go in the evening because of all the neon lighting.
Hyogo / Kinosaki Onsen
- Konoyu. Furthest from the train station. This public onsen has one of the best outdoor area among all the bath houses here. Worth visiting as the building is nice and pretty.
- Goshonoyu. This one has a really big entrance area like some old Japanese temple. The outdoor area is fantastic as it has a fake waterfall and different levels you can climb up to. The indoor pools are also interesting. Probably the best public onsen in Kinosaki?
- Ichinoyu
Large building just beside the main road. Compared to the 2 above, rather utilitarian and modern. Can skip if you have no time.
Hyogo / Arima Onsen / Gekkoen Yugetsusanso
Fantastic onsen hotel. It has access to the onsen baths of 2 hotels side by side - 3 outdoor pools and 2 indoor ones. One is just by the side of the river and the male outdoor pool can even been peeked at from the main lobby of Gekkoen. This is the pool for those exhibitionists! One of the outdoor pools and one of the indoor pool have the gold baths while the rest are all silver baths.
Kyoto / Ohara / Ohara no Sato onsen
This is a minshuku and the outdoor onsen is a big pot that can fit about 3 person max. A beautiful garden surrounds the big pot.
Nara / Totsukawa / Sansui Ryokan
Lovely indoor and outdoor onsen pool in the middle of the Kohechi Kodo. I think this is a nicer place to relax in the middle of the killer walk from Koyasan than the usual Subaru Hotel nearby.
Wakayama / Yunomine Onsen / Adumaya Ryokan
The famous old ryokan in Yunomine Onsen town. The indoor onsen bath here is pretty big and nice, while the outdoor pool is really too small. But the UNESCO rated onsen bath, Tsuboyu (which is really the size of a toilet cubicle) is just opposite the ryokan.
Wakayama / Nachikatsuura / Urashima Hotel
This is a famous hotel in Wakayama that is built on a small peninsula next to the sea. It is huge sprawling hotel and it has many (5or 6?) different wings which are evidently built in different eras. Every wing has their own onsen pools and they are all different. One of the challenges they have for all hotel guests is to visit all the different pools within their stay. The most spectacular pool is one which is build in a sea cave and you can watch sunrise from the pool.
Toyama / Gokayama / Kurobo Onsen
Built on the side of a dam lake, it has beautiful views of the surrounding hills from the outdoor pool. You need a car to get to this onsen, or ask if your accommodation can provide transport.
Gifu / Okuhida / Yarimikan Onsen Ryokan
This fantastic ryokan has several outdoor and indoor baths areas. Several of their onsen baths are in this garden by the river where you can wander about. There is one bath house where there is a wooden slide where you can slide into the pool (obviously targeted at the younger guests). One of the bigger outdoor pools is mixed gender and you can view the fantastic beauty of the river and the mountains that rises majestically from the opposite bank. I had one of my best outdoor winter experiences here soaking in a hot water while it was snowing heavily on my head.
Nagano / Shibu Onsen
There are 9 public onsens in this town, and most which are only accessible if you stay in one of the accommodations in the town (you will get a key to access all the doors to the onsens). It is fun wandering around the small narrow streets of the town trying to get to the next onsen. Most of the onsen baths are really tiny bath houses with only a pool and nothing else. And the water here is really crazy hot (44 plus deg in my estimation, add a bit of cold water if you cannot take it, but don't overdo it since it is a public bath). The fun here is really in going around the small quaint town hunting for the onsens than the tiny onsens themselves.
Nagano / Shichimi Onsen / Keizantei
A rather difficult to get to place. I got here by irregular public buses from Nagano, but check the bus schedule. The private onsen pool here is beautiful in autumn.
