Iwaizumi岩泉
One full day is enough for Iwaizumi: visit Ryusendo Cave, explore the town centre and relax at an onsen hotel.
Iwaizumi is a large, sparsely populated town in Iwate Prefecture, known for its limestone caves and clear spring water. The main attractions – Ryusendo Cave, Sugawatari Cave and the onsen hotel – are close together, so a single day covers the highlights. Overnight is only needed if you want a relaxed onsen stay.
