[Karaoke] Easy-to-sing songs by Dai Hirai, with explanations

Vocal coachKubota Mami
After working as a voice trainer at a studio for seven years, I went independent in 2025. To date, I’ve taught more than 300 students. Honestly, I started teaching out of simple curiosity (lol). When I was job hunting, I stumbled across a listing for a “vocal instructor,” thought, “What is this?!” and applied on impulse. That’s how I became a teacher with zero prior knowledge—so I went through more training than anyone and studied a lot on my own. When I started teaching what I’d learned to my students, their responses were really positive, and that’s when I felt a real sense of purpose. As a teacher, I absolutely love those moments when I’m growing together with my students. As for my musical activities, I’ve been playing bass in a wind ensemble since high school and still do. I’ve also performed live in a band as a singing bassist, and sometimes I’m invited to sing as a vocalist only. Through vocal training, I want to keep using my voice and stay healthy and beautiful for years to come!

I’ve worked in a variety of roles—regardless of pro or amateur settings—including live event PA, cameraman for video and photography, restaurant staff, and logistics center staff. I now spend my days as a part-time writer. I’ve contributed to music and manga websites with feature/review articles, and wrote the liner notes included as a bonus for 1st PLACE Inc.’s “IA SUPER BEST.” As for my music background, I started playing guitar in junior high and focused on band activities during my school years. For over 15 years since then, up to the present, I’ve continued releasing original tracks as a Vocaloid producer. My areas of expertise are Japanese rock, Vocaloid, and manga.

[Karaoke] Easy-to-sing songs by Dai Hirai with explanations (11–20)

Gate of GloryHirai Dai

Dai Hirai / The Door of Glory (Music Video)

Gate of GloryHirai Dai

A support song for high school baseball in the summer of 2022, created as the theme song for “Netto Koshien,” it’s a track that encourages the players with the message: “We want you to hold on to hope beyond winning and losing.” With warm words, a gentle vocal tone, and a catchy melody, it’s crafted to resonate not only with high school ballplayers but with many people.

The overall delivery is soft, so you’ll want to sing without forcing it; however, the switch from chest voice to falsetto at the start of the chorus may be tricky.

Try keeping your facial muscles lifted from the beginning to make the transition smoother.

Always aim to resonate in the same spot—both chest and falsetto—around the center of your brow.

Since it uses a lot of breath, be sure to take a solid inhale in advance!

Island Queen feat. ALEXXXHirai Dai

Hirai Dai / Island Queen feat. ALEXXX from “ALOHA”

Island Queen feat. ALEXXXHirai Dai

Island Queen feat.

ALEXXX, a masterpiece by Dai Hirai, is notable for its sweet lyrics and catchy melody.

Because the song is sung in a low register throughout, it’s recommended even for those who struggle with high notes.

There’s a light falsetto in both the pre-chorus and the chorus.

In the pre-chorus, it appears only briefly, so focus more on matching the pitch than on producing a perfectly clean tone.

In the chorus, it shows up in the backing vocals, so if you’re singing it at karaoke, a good option is to let the guide vocal handle that part.

That said, neither falsetto section is particularly difficult, so give it a try.

DreamHirai Dai

Hirai Dai / Dream (Music Video)

DreamHirai Dai

Hirai Dai’s song “Dream,” which strongly features EDM elements.

While it’s basically pop music, aspects like the clearly defined build-ups give it that EDM flavor.

The most singable point of this track is, above all, the scarcity of long sustained notes.

Although there are relatively many instances of falsetto, the lack of long tones means you don’t need to worry about breathing.

If the falsetto parts are too difficult, adjust the key so that those sections can be sung in your highest comfortable chest voice.

A Song for YouHirai Dai

A Song for You

A Song for YouHirai Dai

A Song for You is a track with a refreshing, memorable melody—a bright song packed with the charm of Dai Hirai.

The easiest point for singing this piece is, above all, how naturally the rhythm falls into place.

Since it’s built on a four-beat feel, which is the most intuitive for Japanese listeners, you shouldn’t have any trouble with the opening.

However, be aware that the chorus brings in a touch of falsetto.

Rather than lowering the key to handle the falsetto sections, I think it’s easier to raise the key by one or two steps so the falsetto sits in a more accessible range.

It’s a strategy that works well precisely because the non-falsetto range of the song is on the lower side.

Give it a try!

FAMILY SONGHirai Dai

FAMILY SONG

FAMILY SONGHirai Dai

Hirai Dai’s iconic song “FAMILY SONG” is striking for its chill vibe.

While he usually centers his music around R&B and Hawaiian styles, this track notably leans toward a country sound.

The easiest-to-sing aspect of this song is, above all, its narrow vocal range.

Although Hirai Dai’s songs tend to span a wider range, this one is among the narrowest in his catalog.

There are few long notes, and there’s little in the way of vocal runs (often called “feints” in Japanese, akin to ornamented phrasing), making it an easy song to sing even for those with lower voices or who aren’t confident singers.

The Light ~Blue Sky~Hirai Dai

Dai Hirai / The Light ~Blue Sky~ (Music Video)

The Light ~Blue Sky~Hirai Dai

The piece “The Light ~Blue Sky~,” with its moving melody and striking lyrics, leaves a strong impression.

For Dai Hirai’s songs, this one leans a bit more toward a rock taste.

That said, to be frank, it’s not an easy song to sing! The reason lies in the falsetto at the start of the chorus.

Most people will find that part difficult.

In that case, try lowering the key so you can sing the falsetto at the beginning of the final, post-modulation chorus in chest voice.

Once you lower the key, it turns into a lower-difficulty song with a rhythm that’s easier to lock into.

[Karaoke] Easy-to-sing Songs by Dai Hirai with Explanations (21–30)

MIRROR MIRRORHirai Dai

Dai Hirai / MIRROR MIRROR (Lyric Video)

MIRROR MIRRORHirai Dai

Released for streaming on July 25, 2021, it’s the theme song for ABEMA’s documentary program “What I Learned After Becoming a Mom at 16, Even Though I Was Supposed to Be an Ordinary High School Girl.” It features Dai Hirai’s characteristically warm, gentle vocals and acoustic sound, with lyrics that straightforwardly convey a “mirror-like” relationship and mutual care.

The song itself is on the shorter side at under three minutes, making it easy to memorize; the melody is easy to imagine and match pitch to as well.

The background rhythm-keeping sounds are very important, so listen carefully and lay the lyrics on top.

If your body moves naturally, you’ll be able to sing it stylishly and coolly!
