“Itoigawa surprised me. In this sleepy small town on the Sea of Japan coast you can find much of the essence of Japan, from the freshest seafood at the quayside market, to the local bonsai master tending thousand year old trees. There is more discover in this tiny area than I ever imagined.”

Alastair Donnelly, Director
