Hiking in the area during the weekend, it was a very hot and humid day when I arrived at the station. In short I needed some great refreshment and asked at the taxi stand if they know a good place to get some real Japanese relaxation. A short walk and I was at this fantastic traditional style complex with spa, restaurant and sauna. My plan was to stay only for a short time but ended up to have spent almost 3 hours at the facilities.

Kawara no Yu is a great place to relax after a hard day, workout or just because you are in the area. It's about a 15 minute walk from Ogawa-machi station (Saitama), and caters to groups of people who would like a great onsen experience. While there is some English to help out the non-Japanese speaker, it would be best to ask staff members if you don't understand something. I've heard this place can get really busy on weekends during the day, so if you are able to make it at night you may have more room for yourself. (Crowded baths are not as much fun, nor are they as relaxing) There is also a discounted price (around 1000-1200 yen or so??) if you arrive after a certain time on the weekend/weekday past 8pm. This is a great price considering you have access to all the different baths, your own robe and towel, and also you get complementary tea in the dining area. It's definitely worth a visit if you are in the area, and enjoy hot baths.
