This is a special episode called "Japan's Before Holiday Big Problems Investigation". The first topic was rivalry between cities, such as Sanjo vs Tsubame in Niigata and Hachinohe vs Tsugaru in Aomori. Next, they investigated again about various dialects in Japan. For example in Hakata dialect, the "sa-shi-su-se-so" line became "sha-shi-shu-she-sho". While in Kishu dialect of Wakayama, "za-zi-zu-ze-zo" line became "da-zi-zu-de-do". After that they watched "Saitama Headline News", which included Hanyu City which rode the wave from figure skater Yuzuru Hanyu's popularity and some events for the Tokyo Olympics will be held in Saitama. Then the hosts were told to welcome a special guest who will ride a bike to the set. Both hosts thought it was Mr. Kiritani, but it was Kazunari Ninomiya who came. The 3 people in the studio then watched a video of Mr. Kiritani's trip to Las Vegas and Los Angeles. Next video was about various attractions in Japan that foreigners unexpectedly love. For example, Australians love to visit a bar where one of the worker is a monkey. Lastly, Murakami revealed his jealousy to Yuya Tegoshi and Nino then suggested Murakami to quit his group in order to make himself "noticeable". (Source: kisskh)
