Astro BoyKamitakada Shonen Gasshodan

It’s the theme song of the 1960s youth anime Astro Boy.

It has a catchy rhythm, a narrow pitch range, and a repetitive structure, making it easy to sing, and it works great as a lively karaoke number.

It’s an uplifting classic.

It’s an anime about a cyborg hero.

Back then, it didn’t feel realistic, so I just watched it thinking it was a cool, ordinary anime.

But now that androids and human-shaped AI robots exist in the real world, it’s a bit intriguing to think that combat-capable ones might actually become possible.

It’s a hugely popular, charismatic anime that has boys totally hooked, and even the erasers featuring its characters became a trend.

Its theme song is also frequently sung and used at events, so it’s a familiar tune.

It might be a good one to sing solo at karaoke to blow off some steam.

Heidi, Girl of the AlpsIju Kayoko

It’s a girls’ anime, but the theme song still gets played across various media even now, so many people probably know it.

With its alpine horn and yodeling in the intro, it’s a piece that conjures up the majestic scenery of the Alps.

DevilmanJuda Keizō

Go Nagai’s cool anime works.

Devilman continues to be remade even today, evolving to become even cooler.

Wasn’t the transformation scene absolutely amazing? Characters that inspire admiration regardless of gender are always cool across generations.

Ladybug SongHorie Mitsuko

The anime “Tentōmushi no Uta” was like a funny and moving drama, where the bond among seven siblings helps them overcome hardships and difficulties.

Its theme song is also very bright and energetic, giving a sense of hope.

If you find it really nostalgic and can sing the whole thing, you’re quite the dedicated fan.

YAWARAMariko Nagai

At the time, the theme song was sung by top singer Mariko Nagai.

The theme songs for this anime were unusual in that they changed every short cour, and Miki Imai also performed one.

I realize anew how amazing this anime is.

The songs are easy enough for men to sing as well, so why not give them a try?
