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.

It’s a ballad that gently embraces all the feelings that come after a fight.

Sometimes a small spat can escalate before you know it, right? When you end up saying too much, the tender yet warm melody and lyrics feel like they’re wrapping you up, and it really hits home.

Ken Hirai’s clear, translucent voice is irresistible, too.

As the saying goes, the more you fight, the closer you are—there are surely things you only realize after a quarrel.

Once you’ve calmed down, try sharing your honest feelings.

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.

This is the theme song for Doraemon the Movie: Nobita’s Great Adventure in the Antarctic Kachi Kochi, released on March 1, 2017.

It was her first anime theme song, written to evoke the bond between Doraemon and Nobita—a touching medium ballad that resonates with the heart.

The accompaniment is piano throughout, and if you sing without rushing, the tempo shouldn’t run.

Since it’s basically sung gently, lightly resonating in the nose and head as if you were humming will suit the atmosphere perfectly.

When humming, use plenty of breath as if you’re humming a tune.

Be careful not to produce the sound in your throat, as that will turn into a throaty voice.

Ken Hirai’s 20th single, “Hitomi wo Tojite,” was released in 2004.

The song was also the theme for the film “Crying Out Love, in the Center of the World,” which became a social phenomenon during the ‘Sekachu’ boom.

It’s strongly associated with that image and is widely known as a classic tear-jerking love song.

There are songs you find yourself wanting to listen to from time to time, ones that never fade with age—and I think this is one of them.

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.
