Shimabara Onsen

On the eastern side of the Shimabara Peninsula, this spa rises in the castle town of Shimabara, which faces the Ariake Sea. Known as a City of Water where clear springs bubble up all over town, it also yields warm, iron bearing hot spring water from the same ground. You can ease your travel fatigue while enjoying the historic streets and sea views.

Highlights

Shimabara Castle, crowned by its keep, is the towns symbol. Samurai residences remain nearby, and one atmospheric lane has clear water flowing down its center. The Koi no Oyogu Machi, where carp swim in spring fed canals, is perfect for a stroll. The water is a reddish iron spring that warms you from the core.

Enjoying the Seasons

In summer the cool air born of the springs feels wonderful, while in winter a bath with a sea view is a special treat. Spring and autumn are comfortable for walking the castle town, and you can wander while tasting kanzarashi, the local sweet iced dessert.

Access and Basic Information

It is close to a station on the Shimabara Railway, so rail access is easy. Ferries link it with the Kumamoto side, making it a base for crossing Kyushu. Inns line the shore, and some facilities offer day use bathing.

A Quick Tip

Iron rich water can stain towels, so it is safer to avoid fine white ones. Pairing your visit with a walk among the springs and canals is highly recommended.
