I just love this hot spring. Amazing, very clean, affordable and super serene! It is also near Tobu-dobutsukoen station. You can walk around 20 to 25 mins from the east exit. Moreover, they provide a shuttle service back and forth. The shuttle is across the bridge from the east exit of the train station. It runs every 30 mins. This onsen is really beautiful and has complete amenities from lotion, cream, soap and different hot spring pools. I like their pool with a warm spring water of around 45° celsius. I visited this 3 times during my 3 week stay in Saitama area. 1100 Yen for an adult during weekdays and on weekends, 1200 Yen. With this price, the towels (face and body) plus yukata (the dress worn after you finish onsen) are included. In some onsen, you rent the towels and they don't have yukata. I highly recommend this onsen in Saitama!
