Udo-chan travels around Mino city in Gifu prefecture with a popular Japanese actor, Koji Yamamoto, and a former member of AKB48, Kayo Noro. They take a train on Nagara-gawa line and walk around wherever they wish.
Mino city is famous for some traditional craft; one of them is edged tools like “Katana” sword. At first, they visit a cutlery museum and try blade shaping there. After having lunch at a café they found on the way to a station, they go to a famous place –a group of traditional buildings preserved for over 400 years. In the Edo era, there was a unique construction style of roofs called “Udatsu.” They visit a sake-factory and a museum for lanterns made by “Washi” paper which is originally manufactured in Mino city. Then they visit a 1300-year-old shrine and find a strange sign on the map which marks a tree named “What tree?”
