Kobukuro “Sakura”

A renowned ballad that evokes a tender, bittersweet feeling along with the gentle warmth of spring.

Released in November 2005 as Kobukuro’s 12th single, it became widely beloved as the theme song for the Fuji TV drama “Ns’ Aoi.” Cherished and performed since their indie days, this song also serves as an important opening number on the album “NAMELESS WORLD.” Its lyrics, which layer the subtleties of life onto falling flower petals, have been highly praised for their literary quality—so much so that they were included in a high school textbook—and the beautiful resonance of the Japanese language deeply touches the heart.

It is a springtime standard that continues to be loved, gently accompanying not only those embarking on a new chapter, but also anyone who wishes to pause and reflect on the past.

Kobukuro “Red Thread”

Kobukuro is a duo that produced many classic songs in the mid-Heisei era.

When it came to ballad duos back then, Kobukuro was the go-to choice.

Among their works, Akai Ito is especially renowned as a deeply moving masterpiece.

The lyrics vividly evoke scenes, the plaintive A-melody, the gradually rising intensity in the B-melody, and the enveloping chorus—every section is captivating, and harmonies appear throughout.

The delicate harmonies that never interfere with Mr.

Kobuchi’s lead melody are superb, so if you want to master harmonizing, be sure to try singing it.

Kobukuro – WINDING ROAD (Ayaka × Kobukuro)

In the late 2000s to early 2010s, when it came to mixed-gender harmony songs, “WINDING ROAD” was the go-to classic.

This track is a collaboration between the pop duo Kobukuro—who enjoyed immense mainstream support at the time—and singer-songwriter Ayaka.

It’s an upbeat piece with a groove that feels somewhat Western-influenced.

That said, as a harmony song, it’s relatively easy, with clearly separated parts, so beginners in vocals should definitely give it a try.

Kobukuro – Oh flowers now in full bloom

This is a song that was used as the theme for NHK’s Sochi Olympics in 2014.

Many of you are probably familiar with it.

Although it’s a song by Kobukuro, “Ima, Saki Hokoru Hanatachi yo” has a very clear vocal melody, making it easy to sing even solo.

As for how to feel the rhythm, taking it slowly and relaxed works well, but doubling the tempo also makes it easier to sing and is recommended.

The overall vocal range of the song is C3 to F#4, so most men should be able to sing it comfortably in chest voice.

Also, since it’s a ballad, creating contrast between the lower parts of the verses (A and B sections) and the lift in the chorus will enhance expressiveness and help boost your score.

Try to keep your facial muscles lifted so your pitch doesn’t drop while you sing!
