Let's become a family on a train trip to Ekiben. A hairdresser named Kotetsu and a programmer named Kotetsu have been together for ten years. Taking this opportunity, they decided to take JR's longest one-way ticket journey from Wakkanai City, Hokkaido, where Kotetsu lived with his grandparents, to Kohoku Town, Kishima District, Saga Prefecture, where Tori's family lived. The wish of Kotetsu, an iron nerd, has come true. He was also looking forward to being able to introduce sightseeing, ekiben, and Kotetsu to his family. Draw a map of Japan from north to south, covering a total distance of over 10,000 km! Squid rice, beef, shrimp, 1,000 ryo chirashi, car, beef story, Kaganodate bento, popular rice, Arita-yaki curry, delicious ekiben, and a train journey.
