Kosaka portrays Muruyo Hakataminami (the owner of Carat, mentor to the Kiramagers, and Younger Brother to Kiramei Silver) on
Mashin Sentai Kiramager. His role as Pikotaro (most notably making PPAP) has been referenced many times, including (but not limited to): • In the main base, a poster can be seen reading "
Perfect
Performance
And
Physical" in an
Acrostic style. • Episode 16's pre-credits scene has Juuru holding a pineapple and an apple while asking whether Mixelan (the new mecha, and a cement mixer) can mix fruit. Hakataminami is standing next to him the whole time. • In the movie, he earnestly performs the song to wake the team up during a fight with a dream-themed monster. Footage of Kosaka's
Pineapple Pen song was utilized in
The Emoji Movie. == References ==
