Your trip to Japan can never be complete without visiting the famous hot springs. And if you are in Noboribetsu, you are in for a treat. It is home to Oyunumagawa, a small hot spring river flowing from Lake Oyunuma. If you take a bus or taxi from JR Noboribetsu Station, you will hardly need 15 minutes to reach here. You will have to hike through the woods to reach this hot spring. After a tiring hike, sitting along the stream and dipping your feet in mineral-rich water feels soothing. And the best part is, this natural footbath area is absolutely free!
