tonight

Among Hirai Dai’s songs, the especially easy-to-sing and highly recommended one is “tonight.” It’s a love song with poignant lyrics and a sweet vocal tone, and it drew attention after being used on the reality show Terrace House: Aloha State! It’s a ballad with a relaxed tempo, and the overall range is C3–A4, which sits in a range that lets you sing as if speaking softly.

There are parts in the chorus sung gently in falsetto and some humming, so a sense of relaxation is crucial.

You’ll use more breath than you think, so instead of inhaling through your nose, breathe in through your mouth and release all of it in a thin stream together with your voice.

Imagining the sound resonating in your forehead or the top of your head should make it easier to produce!

Hirai Dai “Recipe for Happiness” Anime MV | TV Anime “The Apothecary Diaries” Season 2 Ending Theme

This number by Dai Hirai, with its warm vocals and comfortable mid-tempo groove, gently wraps around the frustrations of unrequited love.

What’s so appealing about this song is its choice to view the unbridgeable distance and bittersweet longing from a deliberately positive perspective.

Released in January 2025, it’s a tie-in track written as the ending theme for Season 2 of the hugely popular anime The Apothecary Diaries.

It deftly captures the awkward relationships depicted in the story, vividly expressing how the feelings that snag at the heart are processed like a good medicine.

A Good DayHirai Dai19rank/position

Hirai Dai / A Good Day (Music Video)

The theme is a day off—a heartwarming slow number perfect for a relaxed day.

The song has an easygoing tempo with a laid-back groove you can sway to.

It feels more suited for daytime karaoke than nighttime! Since all the lyrics are in English, if that’s tough for you, I recommend slowing the playback speed on YouTube and going through the lyrics one by one.

If you get into the rhythm, the words will fall into place and it should be easy to sing! The vocal range isn’t too high, so loosen up your shoulders and sing in a relaxed way!
