The ancient town of Kakunodate, in Akita Prefecture, northern Japan, is steeped in history. For visitors, it is like a time slip — back to the period when the streets were filled with samurai warriors. In the old days it developed as a castle town and became a regional hub, both economically and culturally. Many vestiges remain from the Edo Period (1603-1868), including former samurai residences, which are open to the public. On this edition of Journeys in Japan, Peter MacMillan explores this fascinating town, which is known as the "little Kyoto of the Michinoku region".
