A short walk from the train station leads to Kiyosu Castle—a photogenic fortress once tied to Oda Nobunaga. Between the lantern-lined bridge, quiet museum, and stunning top-floor views, this small but historic site makes a perfect half-day trip from Nagoya.

One of Japan’s oldest surviving castles, Inuyama Castle offers preserved wooden interiors, river views, and a peaceful walk through historic streets and along the Kiso River.
