Precisely because we love, our hearts ache at the thought that a farewell will someday come.

Someday We’ll Have to Part, which captures that feeling, was released in 2008 and was chosen as the theme song for the film I Remember the Sky.

Its lyrics remind us that even happy days will one day end, which is why we should cherish the present and love the people we care about with all our hearts.

With its gentle melody and a range that isn’t too wide, it’s easy to sing.

Try singing it while thinking of someone precious to you.

A fragile, gentle ballad produced by Seiji Kameda that sings of the sorrow and love of losing someone dear, it served as the theme song for the film “Ghost: Mou Ichido Dakishimetai,” released on November 10, 2010.

A dramatic signature song commemorating the 15th anniversary of his debut, its music video features Ken Hirai himself giving a powerful performance as a deceased man, resulting in a deeply moving work.

The song’s overall vocal range is E3–D5, roughly two octaves, and as long as you can produce low notes and falsetto without strain, it shouldn’t pose much difficulty.

Try projecting your voice as if pulling it toward the back of your head—you may find it a bit easier to sing.

This is the theme song for the Fuji TV drama “Wonderful Life” starring Takashi Sorimachi, and it marks the first time Ken Hirai has attempted a “one-man a cappella,” with every sound recorded using only his own voice and body—resulting in a soothing piece.

The song’s overall vocal range is B2 to C#5, and since Ken Hirai’s songs typically have wide ranges, the key point is how to produce the high notes with ease.

As this work isn’t the type that requires belting, it’s best to keep a light singing approach throughout.

For both low and high notes, aim to resonate in the head while lifting your facial muscles as you sing.

Catch Ball,” said to be a song Ken Hirai wrote about his own father.

After being included on the 1996 album “Stare At,” it was also featured as a B-side on the 1997 single “HEAT UP.” It’s a song that inspires you to resolve to do your best so you can properly respond to a father who always cared about you.

With its simple, gentle melody, it’s easy to sing even for those who aren’t confident at karaoke.

Try singing it while thinking of your own parents.

Canvas weaves words like painting to capture the faint, bittersweet memories nestled in the precious days of youth.

Released in 2008 as a double A-side single along with “You Are Su-te-ki ♡,” this song was chosen as the theme for the drama Honey and Clover.

Since it spans a relatively wide vocal range, you’ll want to pay some attention to key selection.

Overall, the lyrics flow gently and unhurriedly, making the melody itself easy to sing.

If you’d like to try a song with a broader range, this makes a great entry point.

This is a collaborative song by Ken Hirai and Namie Amuro that sharply depicts the contradictions and conflicts lurking within the human psyche.

Released in April 2014 as their 36th single, it serves as a slightly twisted anthem for everyone wrestling with life.

The music video, themed around a courtroom, also drew attention, and the song reached No.

4 on the Oricon Weekly Singles Chart.

Offering a chance to confront one’s inner self, this track carries deep meaning for those of us living in the age of social media.

If you’re singing it at karaoke, it’s recommended for moments when you and your friends want to lay your true feelings on the table.

Written and composed by Ken Hirai himself, this ballad captures the tenderness felt at the moment of parting and the poignant ache of a heart drifting away, and it was also used as the image song for the 25th Toyota Cup.

Because it is sung quietly throughout with only piano accompaniment, the delicacy of the vocals stands out.

It’s not a belting style, so I think it’s best to keep the resonance placed in the head consistently as you sing.

If you, like Ken Hirai, consciously lift your eyebrows firmly and aim a thin, straight-upward tone, it should make it easier even for those who struggle with falsetto.

Ken Hirai does this unconsciously too, so try singing while imitating the way he sings.
