Melancholic Vocaloid songs: masterpieces that pierce the heart

Minazuki (the traditional Japanese name for the sixth month)Winter Pavilion

Minazuki / Kagamine Len

This is a work by Fuyukan that feels as if the very atmosphere of early summer has been turned into sound.

Kagamine Len’s heartrending vocals and the Japanese-style arrangement are a perfect match.

The song portrays a bittersweet longing for a season that has passed, and the quiet, helpless feelings of thinking about someone precious who is no longer here.

The melody line that sparks the imagination is outstanding.

Why not take some time alone after the rain to fully immerse yourself in its world?

Don't Say Goodbye (feat. Kafu)

There are nights when you’ll hate your own weakness… and this is something that will stay close to those feelings.

It’s a song by Karo-P and MIMI, known for their heart-touching style, released in June 2023.

Featuring a simple arrangement centered on acoustic guitar and piano, it gives the sense that the vocals and lyrics come straight into your ears.

Many listeners will surely find comfort in its message: “It’s okay not to push yourself—wait for the moment when you can face forward.”

Taketombo / feat. Vocoflex

A heartrending melody and lyrics that leave a deep mark on the heart.

It’s a song by Tota Kasamura, released in May 2024.

The feelings of someone who has gone through a breakup are portrayed with delicate nuance.

The gentle tones of the piano and the strong, resonant vocals create a harmony you can’t help but be absorbed in.

And the repeated words “It’s okay”.

it truly shakes the soul.

Of course, it’s wonderful to listen to yourself, but if you have a friend who’s struggling, sending it to them might just help.

I can't sayshikido

I Can't Say It / Hatsune Miku

I want to tell the person I like how I feel, but I just can’t put it into words.

Haven’t we all experienced that frustrating feeling? This song by Vocaloid producer shikido delicately portrays those hidden emotions in the heart.

Hatsune Miku’s crystal-clear vocals and the pop sound tinged with wistfulness highlight the purity of those feelings.

If you listen to it when you can’t bring yourself to confess, you’ll likely see yourself in the protagonist.

FABRICATED / Kyohei Kitazawa feat. Hatsune Miku

This is Kyohei Kitazawa’s “Ichi-1,” released in July 2025.

Sung over a deep, immersive beat, it explores precarious, ephemeral themes of manufactured warmth and fabricated memories.

With Hatsune Miku’s matter-of-fact vocals, it lyrically portrays the protagonist’s heart wavering on the boundary between reality and fiction.

Listen on a contemplative night or when you’re in a slightly sentimental mood, and this mysterious, beautiful soundscape is sure to capture you.

OrangeToma

The one who did a cover of “Orange” is Megatera Zero.

When the topic turns to moving Vocaloid songs, this is a track that almost always gets mentioned.

The original is great, of course, but I also recommend the version sung by the utaite Megatera Zero—it conveys both power and gentleness.

Winter has come to an end.Healthy Cathedral

Winter Has Announced Its End / KAITO V1 & V3 – Sukoyaka Cathedral [VOCALOID Original Song]

You can see a scene of a sorrowful farewell emerging.

Created by Sukoyaka Cathedral and released in February 2025, it features vocal work using two versions of KAITO, V1 and V3, beautifully expressing the changing seasons and the ache of parting.

Just following the singing voice is enough to bring tears to your eyes.

In addition, the development toward the latter half of the song feels as if overflowing emotions have been turned directly into music.

A dramatic KAITO track—be sure to give it a listen.
