Soni Kōgen Onsen Okame-no-yu
A village-run day spa inside the Soni Kōgen Farm Garden at the foot of the Soni plateau, on Nara's eastern edge, where the pampas-grass meadows turn gold in autumn. The sodium-bicarbonate water is remarkably slippery and lives up to its 'beauty bath' reputation, leaving skin silky. The indoor hall has a free-flowing source tub, and the open-air bath looks out to the rock peaks of Kabuto-dake and Yoroi-dake and across the highland (a wood bathroom and a stone bathroom alternate weekly between men and women). Adults ¥900, children ¥500; open 11:00–21:00 (until 20:30 December–March; last entry one hour before), closed Wednesdays (open if a holiday, then closed the next day) and over New Year. A craft brewery, farm shop and restaurant share the site; it gets very busy in pampas season (October–November). About 45 minutes by bus from Nabari Station; about 1 h 50 min by car from Osaka.
