Myōban Yunosato

Onsen in Beppu

On a hillside east of the city centre is this beautiful, rustic, gender-separate stone rotemburo (outdoor bath) with lovely views up and down. Nearby are thatched huts where onsen minerals are harvested using mid-18th-century methods into yunohana bath powder, which is available for purchase. The minerals accumulate inside the huts at a rate of 1mm per day.

You don't need to visit the onsen to visit the bath-powder facility, but fair warning: the shop gets its share of bus tours.
