This is a 90-minute special episode titled: "Japan's Big Big Big Problem". They first investigated Saitama's problems, such as lack of leisure time for Saitama workers and the extreme heat. The latter problem also caused a dispute, since Kumagaya in Saitama and Tatebayashi in Gunma both claimed the hottest city title. Then they checked on the allegations that Tokyo Skytree was not straight. The next problem is Fukuoka, where people shout "Yaa!" when asked to stand or sit. After that, they checked on Banshuu dialect problem, before revealing that the "ugliest dialect" segment (Ep.21) actually received much attention. To comply with the viewers' requests, the show compiled a video of a woman saying "I am Tanaka's mistress" in 46 sample dialect from each prefecture. For the next focus was the weird road signs scattered over Hokkaido, where the show staff used Matsuko's name to ask the authorities. Kayoko Okubo later came to the studio, shared her experience and newest investigation result of "Aomori women are the prettiest in Japan". They also planned to show Yamaguchi women who are said to be "the ugliest", but due to time constraints, it will be continued in the next episode. (Source: Written by MyDramaList)
