Still continuing from the last episode, they investigated more problems in Japan. They re-investigated a lot of problems in the Chubu region, such as writing Niigata (Ep. 72), Nagano salt content patrol (Ep. 57), and Koushuu dialect (Ep. 30). The next topic was about Ishikawa Prefecture, which was often left out when people were asked to draw a map of Japan. After that, they checked on a problem where no one seemed to remember any word that also uses the character ? ("fu") of Gifu Prefecture. Then they focused on the Kinki region, starting from Nara Prefecture, which has too many mascots to people in Kobe who have pride in their city and rarely refer to themselves as from Hyogo Prefecture. They later continued with an interview about Kanto vs Kansai, where both sides did not hesitate to talk bad about each other. In the next investigation, the staff investigated Matsuko's hairstyle during filming. When his hairstyle is a hair bun, he is usually angrier, and the rating for that episode will be high. The staff even asked various experts about this phenomenon. For the last segment, they introduced Matsuko top 3 trending dishes of 2013. (Source: kisskh)
