What is the wake up song used in Gantz?

In the live action Gantz, there is this Japanese old timey song that plays before the cube opens.

The lyrics start with “It’s a new morning; a morning of hope”

Is that an actual historical Japanese song? If so, what is the title?

It’s the Radio Taiso Good Morning Show song. Radio Taiso is an early morning fitness show on NHK Radio in Japan that’s been airing since 1928.

ETA: Great movie, isn’t it? Loads of fun.
