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.
POPS writer/editorKEI
Since discovering music during my school days, I’ve mainly listened to Japanese and Korean pop. I have experience writing articles for sites like Utaten. 2000s J-pop and 2010s K-pop were especially the soundtrack of my youth. With the mindset that “good is good,” I enjoy music across genres. Thanks to past work environments and their influence, I was exposed to lots of classic rock and kayōkyoku (Japanese popular songs), which may have broadened the scope of what I love. At RAG MUSIC, I currently focus on K-pop and J-pop. I strive to edit with a feel for the scene and an eye for hit potential.
