A “new for the hell of it” ouenka. I liked his old one well enough; this new one is fine too except it’s a bit arrhythmically unwieldy.

It’s not really in Japanese at all. It doesn’t have much in the way of lyrics either, so check out the video.
(Music + clapping) Tsuyoshi!
(Music + clapping) Let’s go!
(Music + clapping) Speedostar!
(Music + clapping) Tsuyoshi! Nishioka!

Ok, so that third part is really supposed to be “Speed Star!” or “Speedster!” both of which are cumbersome to sing to say the least. Speedostar is what’s literally being sung and it has the side benefit of being more amusing.
