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

City HunterKohiruimaki Kahoru

It’s a very stylish, grown-up anime that features the hit artist Kahoru Kohiruimaki.

The song was also a big hit and fits the anime’s image perfectly, so it’s essentially inseparable from the work itself—you even get the anime visuals in karaoke.

Burning HeroOkita Hiroyuki

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.

Tontin-kanchin Ikkyu-sanYangu Furesshu

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
dawn roadŌsugi Kumiko

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.

Dr. Slump Arale-chanMizumori Ado

The eternal gag anime, Arale-chan.

Every character is incredibly striking and funny, and it was an anime that made you laugh every week without fail.

The theme song is also enhanced by Ado Mizumori’s cute voice, which brings out the charm of the track.

I love Arale-chan.

Fist of the North Starkurisutaru kingu

A serious anime with the theme song sung by an artist called Crystal King.

Wasn’t it around this time that having artists perform anime songs became the norm? The song fits the anime’s image perfectly—capturing a cool, mature vibe and painting it in a very wild way.

GO!!!FLOW

FLOW “GO!!!” Music Video (TV Anime “NARUTO” Opening Theme)
GO!!!FLOW

GO!!! by FLOW, one of their signature songs and the opening theme for the anime NARUTO.

With its driving momentum, it’s a staple in their live shows and feels very band-oriented.

The song structure builds excitement—verse (A) to pre-chorus (B) to chorus—making it a very satisfying listen.

The vocal range, D#3 to B4, is accessible for the average male singer, but be cautious: the pitch rises slightly at the start of the B section, so avoid forcing your voice and straining your throat.

At a brisk tempo of 135 BPM, it’s highly rhythmic, and the chorus features FLOW’s signature rap.

Since FLOW has two vocalists, try trading lines with a partner or getting the crowd involved when you sing it!
