The black Kumamoto Castle, one of Japan's three great castles; Mt Aso with one of the world's largest calderas; Kurokawa Onsen, a hot-spring town in the hills often called Japan's prettiest; and the Amakusa islands with their dolphins — Kumamoto is the heart of Kyushu, gathering castle, volcano and hot springs all in one.
Honestly, if you're in Kyushu and want a grand castle, a real volcano and beautiful hot springs in one prefecture, Kumamoto is the answer — the black Kumamoto Castle is one of Japan's three great castles (the main keep has been restored and reopened to visitors after the 2016 earthquake). Drive out to Mt Aso and one of the world's largest calderas, climb on to soak at Kurokawa Onsen, often called Japan's prettiest, head to sea at Amakusa for dolphins, and finish with basashi horse sashimi and garlic ramen — all just 40 minutes from Fukuoka by Shinkansen.

🎫 AdmissionAn active volcano inside one of the world's largest calderas, with the steaming Nakadake crater you can approach when the alert level is safe; wide grasslands graze cattle and horses all around.
⚠️ Check volcano levelA hot-spring town in the hills, often rated among the prettiest and most atmospheric; wooden ryokan line the stream, a wooden pass lets you bathe at three open-air baths, and there is a deliberately retro, neon-free feel.
♨️ Bath-hopping passA city-center Japanese garden that recreates the 53 stations of the old Tokaido road, including a miniature Mt Fuji mound, with a clear spring pond and a teahouse — an easy stroll in central Kumamoto.
🎫 AdmissionSouthwestern islands known for year-round wild-dolphin tours, clear sea, fresh seafood and old Christian churches from the hidden-Christian era; you can drive across a chain of five bridges.
🚤 Dolphin tour feeA viewpoint on the rim of the Aso caldera with sweeping views over the crater and grasslands; on some early mornings a sea of cloud fills the basin — a favorite Aso photo spot.

Kumamoto (熊本) sits in the center of Kyushu, with Kumamoto City as its capital. Its symbols are the black Kumamoto Castle, one of Japan's three great castles, and Mt Aso, set in one of the world's largest calderas — and its mascot Kumamon is famous nationwide.
It's easy from Fukuoka, about 40 minutes on the Kyushu Shinkansen. East of the city lie Mt Aso and the valley hot springs of Kurokawa Onsen; to the southwest are the Amakusa islands for dolphin watching. The castle's main keep has been restored and reopened to visitors after the 2016 earthquake.
