Quick answer
The short version: Kurokawa is a bus-only, overnight-first onsen village in the Aso highlands, built around rotenburo-hopping with the nyūtō tegata pass — three stickers, valid six months, usable roughly 8:30–21:00; the tegata costs ¥1,500 for adults and ¥700 for children (about US$10 / US$4.70). One night is the classic visit; two unlocks the valley.

Tips
Buy the tegata at your first bath, not the office queue, on busy weekends.
The 6-month validity means an unused sticker is a reason to return, not a loss.
Cash still rules small inns and shops; bring ¥10,000+ in notes.
Check bath closure boards before walking the valley loop — cleaning closures rotate.
