Nasu Onsen (“ß�{‰·�ò) is a pleasantly old-fashioned, spread-out hot spring resort on the slopes of Mount Nasudake, a highland area also referred to as the Nasu Highlands (“ß�{�‚Œ´, Nasu Kōgen). The center of the resort is the hot spring town of Yumoto, halfway up the mountain. Nasu's hot spring baths were discovered during the Nara Period (710-784) and have been highly regarded for their restorative properties ever since.

Mount Nasudake is also a popular hiking destination. A ropeway leads to within a 45 minute hike of the summit. A variety of other hiking trails cover the mountain slopes, and a pedestrian suspension bridge offers nice views out over the trees. Azalea bushes flower around Nasu Onsen in late May, while the autumn colors peak in early to mid October.

Murder Stone

The murder stone is a large rock - split into two in 2022 - that vents poisonous gases. It is located in a small, volcanically active valley with walking trails and an onsen shrine. The stone is related to a legend of a nine-tailed fox that devastated China and India before coming to Japan. The fox transformed into a beautiful lady to try and seduce the emperor, but was discovered and killed before it could enact its plan. Thereupon the fox's body turned into the murder stone.

The villa is still used as a retreat by the imperial family, but the park was opened to the public in 2011 as a place where people can experience nature. Well maintained trails lead through the forest to huts and observation points. An observation deck at the northwest end of the park offers views out to a waterfall.
