[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!
A Vocaloid producer who is also a music writerAraki Jakkan
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 (31–40)

BeautifulHirai Dai

Beautiful

BeautifulHirai Dai

Hirai Dai’s music is strongly influenced by R&B and Hawaiian music.

Among these, R&B in particular tends to be a very challenging genre for Japanese listeners, as its rhythms can be difficult to grasp.

“Beautiful,” however, leans more toward pop music, so there’s no need to worry about that, and the vocal line is arranged to be easy to sing throughout.

That said, there are occasional falsetto parts, so you’ll need to set an appropriate key.

If you choose a key that feels “slightly high,” it will make the falsetto sections easier to produce—please use this as a reference.

I’ll be there for youHirai Dai

I’ll be there for you

I'll be there for youHirai Dai

Hirai Dai’s masterpiece “I’ll be there for you,” which depicts parting with a loved one.

Its melody is memorable, with the feel of acoustic Western pop music.

In this piece, while the instrumentation follows orthodox pop, the vocal line is somewhat intricate.

It’s not exactly difficult, but because the flow is closer to Western music, that part may be challenging.

Specifically, there are instances where two or more vowels are sung on a single note.

To sing this smoothly, in addition to clear articulation, you’ll need to memorize the vocal lines in units of lyric phrases.

Life is BeautifulHirai Dai

Hirai Dai’s famous song “Life is Beautiful” lets you savor authentic Hawaiian pop.

It’s a laid-back piece with impressively simple instrumentation.

Since it isn’t as bare as a solo voice-and-guitar performance, the vocals don’t stick out awkwardly, and the vocal line has no falsetto or long sustained notes, making it very easy to sing.

If anything, the opening English lyrics might feel challenging.

If you’re not confident with English, try linking the vowel sound at the end of one word to the vowel sound at the beginning of the next.

Dai Hirai / Waikiki Lonely Boy (Lyric Video)

Waikiki Lonely BoyHirai Dai

When you think of Dai Hirai, many people probably picture a musical style influenced by Hawaiian music.

If you want to fully savor that side of him, look no further than Waikiki Lonely Boy.

This piece is distilled into a simple arrangement of just ukulele and vocals, with a languid, wistful mood permeating the entire track.

Because this kind of setup tends to spotlight the vocals, it’s unexpectedly challenging; however, the vocal line here doesn’t reach into high registers and the tempo is relaxed, making it very easy to sing.

Naturally

NaturallyHirai Dai

Hirai Dai is known for his bright, uplifting musical style.

Among his works, “Naturally” is an especially fresh track that’s perfect for sunny days.

Its reggae-like sense of rhythm is distinctive, and because the tempo isn’t fast, it’s very easy to sing.

However, without pronunciation that gives Japanese a more English-like sound, like Hirai Dai’s, it can be hard to make the song sound cool.

When singing, try rolling your “r” sounds more strongly, and pronouncing “a” more like the “ae” sound, among other tweaks.
