A Vocaloid producer who is also a music writerWakachan Araki
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.

How often do you usually listen to Vocaloid songs?

These days, there are so many ways to enjoy music—streaming on subscription services during your commute to school or work, or playing YouTube videos in the background while you’re doing something else.

I’ve handpicked only the ones that really hit hard, so they’re perfect for times when you want to boost your mood or sharpen your focus!
