Ikkyu the Monk OP

This is the opening theme song of the famous anime Ikkyu-san, which aired from 1975 to 1982.

It’s very bright and well-known, perfect for karaoke, and even though it’s sung by a woman in a relatively high key, it would still be exciting if sung an octave lower—an ideal anime song for people in their 60s.

Full of dreamsSeki Yumiko

OP1 – Full of Dreams

This is the song that was used as the first opening theme for the hugely popular anime Chibi Maruko-chan, which is still on the air today.

For many people in their 60s, the anime’s heyday coincided with major life milestones like having children, so it’s sure to evoke a strong sense of nostalgia.

Dunbine, fly!MIO

Aura Battler Dunbine OP

For men in their 40s, I think they’re the Gundam generation, and among Tomino’s works, the song I’d recommend for getting the crowd going at karaoke is the opening theme of Aura Battler Dunbine.

It’s sung by a woman, but the voice is as husky as Yuki Katsuragi’s, so it’s easy for men to sing too.

Take back the love!!kurisutaru kingu

[High Quality] Take Back the Love! (Subtitled).mp4

Many people in their 40s likely grew up watching the anime Fist of the North Star.

If you queue up Crystal King’s “Ai wo Torimodose!!” at karaoke, people in their 40s will almost certainly react.

The memorable intro makes you start humming the chorus the moment you hear it.

Be sure to listen to this song together with fellow 40-somethings and get hyped.

It’s a classic you can sing passionately at karaoke.

Hiroshi Kitadani – We Are! / THE FIRST TAKE

Isn’t it the generation that most people in their 30s watched the most? It’s the first opening theme of the hugely famous anime One Piece.

Its recognition is on a whole different level compared to other songs, so people of all ages can sing it—and it’s even great for group sing-alongs—making it perfect for karaoke, don’t you think?

Aim for No. 1!!Kusao Takeshi

NG Knight Lamune & 40: Aim for Number One!! [Takeshi Kusao]

This is the opening theme song of the anime NG Knight Lamune & 40 from the era when lead voice actors—like Megumi Hayashibara—often sang.

It wasn’t a commercial tie-in; it was created for the anime to get you excited before watching.

So for anime fans in their 30s and 40s, this kind of song is what really resonates when they think of anison (anime songs).

Invisible Power ~INVISIBLE ONE~B’z

B’z / Invisible Power ～INVISIBLE ONE～

It’s the ending theme of the TV anime Hell Teacher Nube.

It was released on March 6, 1996 as B’z’s 19th single.

B’z is a monster band—when you go to karaoke, there’s always someone who picks a B’z song.

If a B’z fan is going to sing an anime song, they’ll choose this one.

By the way, despite being an anime song, it doesn’t have any anime vibe at all.
