Myoban Onsen — Yunohana Sulfur Huts

Myoban Onsen is a hot spring district on Beppu's western hillside famous for yunohana (湯の花, 'hot spring flowers') — crystallized sulfur and minerals harvested from traditional thatched-roof huts. The huts channel geothermal steam through bamboo and thatched grass, where mineral crystals condense and are scraped off monthly. The yunohana is packaged as bath salts, allowing anyone to recreate Beppu's sulfur onsen at home.

The hut field creates a photogenic landscape — dozens of pointed thatched roofs on a hillside emitting steam.
