The episode is a 2 hour special episode labelled as "Spring Japan's Big Problems Investigation". The local segment included people with heavy regional accents who will use standard Japanese in chats, an overly niche card game in Fukuoka, checking whether Kuroki is the most common surname in Miyazaki, the first Don Quijiote in Kochi (feat. the woman from Ep. 540), and a ramen shop owner who is actually the first disciple from Mr. Marik. Next they checked on Mr. Kiritani who was struggling with tax reports and the endless speaker invitations. After that was the English lessons for Osaka people which included vocabularies, listening, and talking with natives. Lastly, it was about Fef Girl and Ota-san. Fef Girl has started rap class while Ota-san is visting more plastic surgery clinics in Seoul. (Source: Griffin Seannery at kisskh)
