Ken Hirai Popular Song Rankings [2026] (21–30)
I love you.Hirai Ken21rank/position
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.
RingHirai Ken22rank/position
It’s the theme song for the NTV Wednesday drama “Psycho Doctor,” and Ken Hirai commented that he created it with the thought, “Maybe everyone is hurting in some way.
Rather than running away from those emotional wounds, it’s important to take your time and love them.” It’s a touching ballad that many people say has saved them.
The tempo is relaxed, making it easy to sing calmly, which is a nice point.
It may not be a very famous song, but the melody line is simple, so I think it’s easy to remember.
There’s a key change before the last chorus that raises the vocal range, so be careful with that part.
Things I like about youHirai Ken23rank/position
A song that brightly and straightforwardly sings about loving your partner.
The lyrics are direct, and it’s a song that makes you think, “I want someone to feel this way about me.” The music video is bright and refreshing too, so I hope everyone enjoys both the video and the song when singing it at karaoke.
ParadiseHirai Ken24rank/position
This is a high-difficulty song with multiple sections where it’s hard to sing without switching to falsetto.
Still, if you practice slowly step by step, I’m sure you’ll be able to sing it.
Glide through it smoothly and fill the karaoke room with a romantic vibe.
A Gift Without a StampHirai Ken25rank/position
Ken Hirai’s “Kitte no Nai Okurimono” (A Gift Without a Stamp) is one of the tracks on his cover album Ken’s Bar III.
He delivers this classic, written and composed by Kazuo Zaitsu, with his uniquely expressive vocals, resulting in a wonderful rendition that can be appreciated not only by fans.

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.
Grotesque feat. Namie AmuroHirai Ken27rank/position
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.
I will fall in love with you.Hirai Ken28rank/position
Boku wa Kimi ni Koi wo Suru is a straightforward, heartfelt song sung to a beloved person you’ll no longer be able to meet.
Released in 2009, it was used as the theme song for the film I Give My First Love to You.
Although the message is passionate, the melody is relaxed, making it easy to sing.
The chorus is a bit high in key while the other parts are relatively low, so be careful when setting the key.
That said, if you adjust the key properly, it’s a song that’s easy for anyone to try, regardless of gender.
Even if the day comes when we partHirai Ken29rank/position
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.

“Shashin (Photograph)” by Ken Hirai was used as the theme song for JRA’s commercials in 2008.
The track is included on his seventh album, FAKIN’ POP.
Hirai wrote this song for his late father, and once you know that, it really hits home that he’s singing to someone who is no longer here.
For those who have lost someone dear or close, it may be a song you can’t listen to without tears.
Ken Hirai’s heartfelt voice loosens the tear ducts all the more.
