Lonely Planet review
Just west of Yamaguchi city is the 800-year-old Yuda Onsen. The area is covered in a rash of hotels and bathing facilities, mostly along a busy main road, which isn't really a place for tottering between baths in your yukata . Still, a soak here is a nice way to spend a few hours.
You can take a dip in the indoor and outdoor baths of Yu-no-Machi Club , use the baths at the large Hotel Kamefuku or, for a taste of luxury and a peaceful garden setting, head to Sansui-en . For a full list and map of the baths and hotels, drop in first at the tourist information office on the main road.
Buses run regularly to Yuda Onsen bus stop from Yamaguchi Station (¥190, 10 minutes). They drop you on the main strip, Yuda Onsen-dōri, a short walk from the tourist office (just keep walking in the direction of the bus). Yuda Onsen also has a station, one stop on the local train line from Yamaguchi (¥140). From the station, follow the red road for about 1km to get to the busy main T-intersection and turn right for the tourist office.
