Yumoto Onsen in Nikko, Japan
Yumoto Onsen is a hot spring city located in the background of the Okinawan National Park. The north is the site of the Temple. This city is most beautiful in autumn and Mid-October. North of the town stands Onsenji, a Buddhist temple with a small hot spring bath open to the public. Next to the temple is Yunodaira Marsh, where most of the town’s hot water bubbles up from the ground. Some hot water is also bubbling along the northern shore of Lake Yunoko, and a pleasant sulfur odor hangs over the whole town.
Yumoto Onsen is connected with central Nikko by Tobu bus. Buses leave from Tobu Nikko Station (many also serve JR Nikko Station) and are bound for Yumoto Onsen. There are one or two buses per hour. The one way trip from Tobu Nikko Station to Yumoto Onsen takes about 80 minutes, costs around 1700 yen and is covered by the Nikko All Area Pass. A 2-day pass for unlimited bus rides between Nikko and Yumoto Onsen is available for 3000 yen at Tobu Nikko Station.
Note that during the autumn leaf season in October, traffic between central Nikko and Yumoto Onsen can be very heavy, and buses can incur heavy delays, especially on weekends. If possible, try to visit during the week and not on weekends.
