Lovely karaoke song

Kazuhiro Hirai’s songs that are easy to sing. Songs I want to sing with emotion.

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.

Catch Ball,” said to be a song Ken Hirai wrote about his own father.
