About 145 years ago, apple tree saplings were imported to Japan and distributed around the country. The place where apple growing put down its strongest roots was in the Tsugaru area of Aomori Prefecture — and now it boasts the largest apple crop in Japan. John Moore travels to Tsugaru during the apple harvest, to meet the local people whose lives are so deeply entwined with the fruit. He learns about the history of apple growing and the hard work involved. And he finds out why this area has come to be known as the Kingdom of Apples.
