A good onsen visit is mostly about timing, and Myoban Onsen is no exception — when you go changes what you get.

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.

What locals know

**Yunohana bath experience:** Myoban's communal bath (Myoban Onsen shared bath, ¥200) uses water heavily laden with yunohana — milky white, strong sulfur smell, acidic pH. The bath is simple (indoor pool only) but authentic. **Yunooka Observatory:** a short walk uphill from the yunohana huts reaches a viewpoint over all of Beppu — the city's steam plumes visible across the urban landscape. Free access, best at dawn or sunset. **Yunohana products:** The shop sells yunohana bath salt (¥500/packet, enough for 2 home baths), yunohana soap, and sulfur-based cosmetics. The bath salt has a 3-year shelf life and makes an excellent souvenir for onsen enthusiasts.
