Biography

Rose to national fame in the 1970s as a regular host on programs such as 'Ginza NOW!' (TBS) and 'Kinyou 10-ji! Uwasa no Channel!!' (Nippon TV). He sparked a nationwide craze with his signature "Nahanaha" comedic pose. Widely recognized across generations, he is also known as the inspiration behind the popular party game "Senda Mitsuo Game." He remains active today in television, radio, and event hosting.

How the Appearance Came About

The opportunity arose from an unexpected coincidence during CM production.

During the creation process, the dance pose featured in the CM reminded the production team of Senda Mitsuo's iconic "Nahanaha" gesture. This sparked the idea: "We'd love to have him perform this pose himself!"—leading directly to the invitation for his appearance.

In the final CM, Senda Mitsuo appears seamlessly integrated into the scene. His signature pose and charismatic presence are subtly incorporated, creating a playful moment that brings a spontaneous smile to viewers who spot him.

His cameo may be easy to miss at first glance—making this "hidden character" appearance one of the CM's highlights. We encourage viewers to watch closely and discover where Senda Mitsuo appears.

Comment from Senda Mitsuo:

"I never imagined I'd appear in a CM like this, but the moment I heard about the concept, I thought, 'This is my chance to reach younger generations! (laugh).' It was my first time ever dancing in a CM.

I truly enjoyed participating in the shoot.

Since my appearance blends naturally into the scene, I hope viewers will have fun searching and wondering, 'Where is he?'

I hope the 'Nahanaha' craze comes back around again! Naha!!"

This shoot also marked a special collaboration between brand ambassador Yuki Poyo and Senda Mitsuo.
