Panther Mukai to Host Full Week on TBS Radio #Flat

Why it matters

The transition of the #Flat program represents a consolidation of the show's format under a single primary host. By moving to a consistent Monday-through-Thursday schedule, the station is likely aiming to build stronger listener retention. The public reaction reflects the established popularity of the radio personalities involved.

TBS Radio has officially announced that the program Yarenz no #Flat will conclude its broadcast run at the end of March 2026. This change will shift the station's weekday programming, allowing Panther member Satoshi Mukai to take over hosting duties from Monday through Thursday beginning in April.

What happened?

During the October 8, 2026, broadcast, the comedy duo Yarenz—composed of Masaki Narahara and Junnosuke Ide—announced their departure from the program. The duo has been responsible for the Thursday morning time slot since April 2024, acting as an alternate for Satoshi Mukai, who had previous recording commitments on that day.

With the conclusion of the Yarenz-led segment, the program is expected to transition into what the hosts described as its "complete form," with Mukai serving as the primary personality for the full weekday schedule.
