You might call it city pop infused with the tones of traditional Japanese instruments—its inventive sound arrangement is the main draw.

The lively tempo alone will lift your spirits.
And the best part of this song is the lyrics.
Especially if you live in the Tohoku region, you’ll probably recognize a lot of the phrases.
It features many Tohoku landmarks, specialties, and even commercial jingles.
It’s a track that fully showcases the “Tohoku Kiritan” character.
Fuzzy Navel____natural

The explosive power of the chorus is incredible, and it makes you want to listen over and over.
It’s a piece by Vocaloid producer ____natural, released in 2020.
The acoustic guitar’s timbre lingers in your ears—such a cool number.
The contrast between that sound and Kiritan’s solid, core-rich vocals is great; it feels like they’re supporting each other.
And perhaps the biggest charm is the melody itself.
The chorus, of course, but the phrases in the A and B sections also seize your heart.
After Talkmawari

A bittersweet yet powerful Kiritan song that makes you feel like “living true to yourself.” It’s a track by Vocaloid producer mawari, released in 2020.
Its soft sonic character wraps jazz-tinged rhythms in the tones of acoustic guitar, strings, and piano.
The arrangement lets you listen in a relaxed mood.
Yet the emotions packed into the lyrics about “ways of living” are deeply stirring.
If you’re looking for a song with depth, this is a must-listen.
Linoleum Alicewatson

This is a tense rock number that reflects the mindset of a protagonist in pursuit of the truth.
The track was created by the Vocaloid producer watson, who also runs a royalty-free music site, and was released in 2021.
Its appeal lies in a melody that conveys beauty within its hardness.
It pairs well with Kiritan’s crisp, clear enunciation.
The lyrics, which reveal a dark worldview, are another highlight.
As you listen, you may strangely find yourself wanting to sing it, too! Be sure to pay attention to the fiery guitar solo!
Bugryanseshite

A stylish rock tune built around a four-on-the-floor rhythm.
It’s a track by Vocaloid producer Shaito, released in 2021.
The sharp guitar, gritty bass, and rolling synth phrases leave a strong impression, resulting in a rhythmical and highly addictive sound.
I also find it an interesting approach to incorporate a Japanese flavor into the chorus melody.
While Kiritan’s natural, straightforward singing voice might tempt you to keep the arrangement equally straight, it actually suits this kind of cutting-edge arrangement as well.
