Male (21–30)

It’s an extremely popular song that should be quite easy to sing for women in terms of vocal range! It’s a signature track by Sakanaction, a band known for their blend of electronic music and rock, released as a single in 2015.

It was written as the theme song for the film Bakuman.

The sound, which combines freshness with a retro vibe, has a power that makes it impossible to stop replaying.

It’s the kind of song you can recommend by saying, “When you go to karaoke, start with this one!”

The band “the Molars,” beloved by hardcore music nerds for their straightforward rock, centers on classic Japanese punk.

They’re marked by unadorned lyrics and direct, no-frills vocals—stylistically, you might call them the Reiwa-era Blue Hearts.

Among their tracks, the one I especially recommend is Desu-Kiss.

While the chorus features some falsetto, the overall range sits in the low-to-mid register, so most men with an average vocal range should be able to sing it in the original key without any trouble.

Butter-FlyWada Kōji

One of the defining anime songs of the Heisei era, this popular track frequently ranks near the top in all-time anime song lists! It’s characterized by its uptempo, powerful melody and vocals, and plenty of people sing it at karaoke.

The chorus in particular stays in the high register, so your stamina and vocal power will be tested.

If you let your guard down even for a moment, your pitch can drop into your throat.

This is a part where you really want to belt comfortably in chest voice, so take in a big breath through your mouth and project your voice far and confidently.

Just that alone should help your voice carry much better.

Keeping your energy up while singing is important too!

SaraiKayama Yūzō & Tanimura Shinji

Some of you reading this article may be a bit older.

For you, I recommend Sarai.

It’s a song well known even among younger generations thanks to its association with 24-Hour TV.

The real charm of this piece lies in its deep, mature vocal line.

Although the arrangement feels grand, the vocal range is very narrow—mid1 A to mid2 F—so men with lower voices should be able to sing it smoothly while making the most of their low tones.

Be sure to check it out.

Goodbye ElegySuda Masaki

This theme is a perfect match for “Sayonara Elegy”! It was released on February 21, 2018, and serves as the theme song for the NTV drama “Todome no Kiss.” The song was written and composed by Huwie Ishizaki, and his own version is also available on streaming services.

Since Masaki Suda’s version has a lower vocal range, I think it’s easier for men to sing.

For the non-chorus parts, singing with a breathy, spoken style suits the mood of the song.

In the latter half of the chorus, the build-up feels like an emotional explosion and is really cool.

There’s a melody line not found in the first chorus that goes a bit higher, so be careful not to force your voice.

The “na-” and “ma-” consonant lines tend to sound nasal and are hard to articulate, so it’s important to enunciate more clearly than you think!

Sign of Lovesupittsu

It makes you want to imitate those unadorned vocals! This track by Spitz, a rock band that’s been at the forefront of the Japanese music scene for many years, was included on their 1999 album “Ka-Cho-Fu-Getsu.” It was originally written for the duo PUFFY.

The relaxed, easygoing guitar rock sound is fantastic—you’ll want to clap along and get into the groove! The vocal range should be easy for most women, and it’s quite approachable for men too.

It also sounds like it would be fun as a duet!

KanadeSukima Suichi

It was Sukima Switch’s second single, released in March 2004.

It landed many tie-ins, including being an insert song for the film “Rough” and the theme song for Night 3 of Fuji TV’s four-night drama series “Sotsu Uta.” Throughout the entire piece, you can feel a warm, easygoing atmosphere—truly one of the Heisei era’s gentle masterpieces.

The vocal melody doesn’t require straining for high notes, so many people should be able to enjoy singing it without changing the key.

Just pay attention to the brief falsetto part that appears for a moment in the chorus.
