Ken Hirai “Precious Junk” MUSIC VIDEO

“Precious Junk” is Ken Hirai’s debut single, and it was used as the theme song for the Fuji TV drama “Ousama no Restaurant” (The King’s Restaurant).

It’s said that Koki Mitani, the screenwriter of the drama, was the one who chose the debut song of this unknown newcomer as the theme.

Ken Hirai struggled until his later hit “Rakuen,” but went on to become one of Japan’s leading singers.

This song is also well-known because many people later realized, “It was Ken Hirai who sang that song from that drama.”

Ken Hirai 'KISS OF LIFE' Music Video

Released on May 16, 2001, this exhilarating pop song served as the theme for Fuji TV’s Monday 9 p.m.

drama “Love Revolution.” It sings about genuine love and the importance of a kiss.

Since the song stays mostly in a high register, it’s recommended for those good at falsetto or high notes.

The melody line isn’t difficult, so it should be easy to learn even if you’re just starting.

The key rises slightly in the final chorus, so nailing that section will make you sound impressive at karaoke.

Try singing with a slightly higher, polished tone in mind.

Love Love LoveHirai Ken17rank/position

Ken Hirai “Love Love Love” MUSIC VIDEO

It’s a song that starts a cappella and incorporates handclaps and gospel-style choruses, singing about love in a fresh and emotionally rich way.

It’s used as the ending theme for the TBS show “Ai no Hinadan.” The track itself features a simple arrangement with piano accompaniment.

Falsetto works well, but belting in a chest-voice style can also sound great.

Just be careful not to strain your throat by pushing too hard.

Using gestures and engaging your whole body while singing can help you stay relaxed, so have fun and sing your heart out.

Missin’ you ～It will break my heart～Hirai Ken18rank/position

Ken Hirai 'Missin’ you ~It will break my heart~' MUSIC VIDEO

The 2002 release “Missin’ you ~It will break my heart~” is a number that conveys the resolve to live on to someone precious you can no longer meet.

The song flows at an overall relaxed pace, making it easy to sing while savoring the lyrics.

There’s a sudden leap to higher notes toward the end, so if that’s not your strong suit, it might be better to start in a slightly lower key.

English lyrics appear frequently, but because the tempo is laid-back, you can sing them calmly without feeling too much pressure.

Ken Hirai “Ring” MUSIC VIDEO

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.

Ken Hirai 'even if' MUSIC VIDEO

“even if” depicts the bittersweet feelings of loving someone who already has a partner.

Released in 2000, the song serves as the theme for Ken Hirai’s concept live series, “Ken’s Bar.” The lyrics express the frustrating emotions of wanting desperately to keep someone from leaving, yet being unable to do so.

Since the overall key is relatively high, it may be easy for women to sing in the original key.

For men who struggle with high keys, try lowering it a bit.

Ken Hirai "half of me" MUSIC VIDEO

It’s the theme song for Fuji TV’s Thursday drama “Twilight Meteor Shower: Midlife, Falling in Love,” a “phantom love ballad” that had been kept under wraps for about nine years since 2009, and it’s said to depict the world ten years after his signature song “even if.” In the music video, it’s striking how half the screen is composed of “blank space” like walls and doors to express the feeling of losing something precious.

Ken Hirai’s beautiful, heartrending voice resonates over the piano accompaniment.

When you sing it, if you deliver each lyric carefully, I think you can recreate that beautiful vocal quality.

Try to be mindful not to rush through it carelessly.
