Singing it at karaoke is sure to lift your spirits.

It’s a famous song that many artists have covered, so even today’s youth know it.

The track was used as the first opening theme for the TV anime Urusei Yatsura, which began airing in 1981, and it’s so well-known that it’s guaranteed to get everyone hyped at karaoke.

Japanese Folktaleshanazukin

This is the opening theme song of the anime “Manga Nihon Mukashibanashi,” which aired for 20 years starting in 1975.

Since it’s sung by a female vocalist, men might change the key or sing an octave lower for a gentle delivery.

It’s a song that can evoke nostalgia and really get people engaged.

Tari-rari-ran no KonyanyachiwaKoromubia Yurikago-kai

This is the theme song of “Ganso Tensai Bakabon.” Unlike the original “Tensai Bakabon” theme, it’s crafted with a space motif and carries a somewhat grander sense of scale.

The very surreal worldview of “Bakabon’s Papa” leaves a lasting impression, and I still think he’s a great figure.
