[2026] Recommended for Men in Their 40s! A Selection of Anime Songs to Sing at Karaoke (21–30)

Mystical, Mysterious Adventure!Takahashi Hiroki

[Female Vocals] Dragon Ball OP: Makafushigi Adventure / Hiroki Takahashi – Cover [Nanao]

The theme song from Dragon Ball was probably the absolute classic among boys back then.

Even now, when you want to hype up a karaoke session with anime songs, it’s always one that comes up.

So let’s all get fired up and sing this one with everything we’ve got.

Protect the Lightsupittsu

It has been selected as the opening theme song for the anime SPY×FAMILY Season 3.

Spitz doesn’t usually have the image of doing anime themes, and it seems this is their first anime.

The gentle tone and melody line slip right into your heart.

Since vocalist Kusano’s voice has a transparent mixed voice quality, you might feel the song is high when you listen, but the actual range is D#3 to A#4, so it’s not excessively high.

However, it can be challenging if you try to force the sound out.

It’s easier if you aim for a light, head-resonant approach.

The ending sits around G#4… I recommend singing it with a humming-like feel without pushing yourself.

Jarinko ChieNakayama Chinatsu

A heartwarming Kansai-style anime.

It’s an adaptation of a serialized manga that became an anime, and the bold personalities of Chie-chan from the horumon shop and her old man are hilarious.

I don’t think there’s any other anime that makes ordinary everyday life this entertaining.

If there were a horumon joint like this, I’d want to go every day!

Tsurikichi SanpeiMOJO

Fisherman Sanpei OP 'Young Traveler' Full Version
Tsurikichi SanpeiMOJO

It was an anime with a very rare theme at the time: a story about a river-fishing prodigy who sparks all kinds of fishing techniques.

I bet a lot of people started collecting fishing gear after watching it.

With all the explanations it gave, I think many boys learned a lot from it.

Cyborg 009Tōkyō Maisutā Jingā

Cyborg 009 (1979) OP 'For Whose Sake' & ED 'Someday'
Cyborg 009Tōkyō Maisutā Jingā

A very serious cyborg anime.

I always felt it was more for adults than for children.

The theme song is stylish with a jazzy vibe, so now that I’m an adult, I can recommend it as an anime song that’s easy to sing without any trouble.

IRIS OUTYonezu Kenshi

Kenshi Yonezu’s masterpiece “IRIS OUT.” Known as a theme song for the anime Chainsaw Man, this track has been crafted with a rather unusual tone to match the show’s atmosphere.

While it carries an overall rock flavor, you can glimpse gothic elements here and there—likely to align with the series’ world, where devils appear.

It has a somewhat matter-of-fact delivery yet interweaves shouts, making it thoroughly engaging to listen to.

Be sure to check it out.

Theme of Lupin the ThirdYū & Ekusupurōjon Bando

By now, it’s an all-time classic—there’s hardly anyone who doesn’t know this song.

It’s a famous tune used for cheering at high school baseball games and as background music.

While the original is instrumental, there’s also a version with lyrics that was used as a theme song, so be sure to try singing it at karaoke.
