Season 1
The CX in the title comes from JOCX, the call sign of Fuji TV. Arino's Challenge began as a short segment in Season 1. Interviews made up most of each episode. ADs (Assistant Directors) introduced in Season 1: Naoki Yamada (M1 only) and Shinichiro Tojima (M5 onward). ADs typically "graduate" from the show after a season or two, but old favorites often return in new roles or on special occasions.
