The first investigation was about various "sacred places". It included a temple famous for bringing luck to lottery tickets, a coriander lovers club, and a place in Nagano which is suited for rugby training in summer. Next topic was an investigation of things that is "not often seen". It included a grass that smelled like fart, a fish that will release excrement when pressed, and a self-proclaimed oldest ganguro gyaru. They later continued to investigate about things that were enjoying growth. It included a growth in twin style clothing and a growing number of people staying overnight in the airport. They also learned about moth invasion in Nagano and interrupted sport matches. To test that, they asked Ryo Kimishima to impersonate Sachiko Kobayashi singing in Nagano Sports Park but did not gather any moths. (Source: MyDramaList)
