[2026] Recommended for men in their 40s! A roundup of anime songs you’ll want to sing at karaoke

Protect the Lightsupittsu

Spitz / Protect the Light

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.

IRIS OUTYonezu Kenshi

Kenshi Yonezu – IRIS OUT

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.

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.

Burning HeroOkita Hiroyuki

TV anime “Captain Tsubasa” non-credit ending sequence

A towering landmark of anime songs that sings of dreams and passion over samba rhythms and a catchy melody! This masterpiece briskly and humorously portrays the presence, skill, and influence of an ace player.

Hiroyuki Okita’s refreshing vocals brilliantly capture the allure of soccer and the throbbing energy of youth.

Released in 1983 as the opening theme for the TV Tokyo anime Captain Tsubasa, it became a classic that helped spark the soccer boom.

In 2018, it was remade by Ryuhei Maruyama of Kanjani Eight.

It’s a song that powerfully pushes the backs of everyone striving toward their dreams—not just soccer fans—and one we highly recommend you listen to.

Tsurikichi SanpeiMOJO

Fisherman Sanpei OP 'Young Traveler' Full Version

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.

Ikkyu the Monk OP

Was it around elementary school when we heard the theme song of Ikkyu-san? Many people were probably impressed, thinking Ikkyu-san was amazing for solving problems with clever wordplay.

There are those who reflect on it and those who don’t—there are many ways to look at it—but in any case, Ikkyu-san was very smart.

World Masterpiece Theater – A Dog of Flanders OP: The Road at Dawn

This is the theme song of the classic A Dog of Flanders.

The contrast between the sadness of the story and the cheerful feel of the theme song makes the content even more heartrending, so you might find yourself in tears while singing it.

The image of Patrash and Nello walking together in harmony forever is very striking.
