Insider tip — 'Hiraogi' (平扇 — flat fan) at Kazoku Onsen in the Hiraogi district of Yamaga — part of the celebrated Hirayama Onsen cluster. Yamaga's Hirayama/Hiraogi area is one of Kumamoto's most revered traditional onsen neighborhoods, with a dense cluster of family baths drawing from the same alkaline volcanic aquifer. The 'flat fan' name may reference the flat-shaped topography of this spring district, or the traditional folding fan aesthetic of Yamaga's famous lantern festival performers.
