It's good to learn the memorization stuff by singing👏 I didn't know this Ku Ku song. My second son will be in elementary school next year, so I will teach it to him.
To memorize prefectural capitals, I recommend “Rock and Roll Prefectural Capitals” by Chisato Moritaka😉

I sent 1 HSBI as a thank-you gift🎁
