Started working as a music writer as a side job while employed at a record shop, and have been contributing to music magazines and web media for over 15 years. Although Western music is my main field, I always strive to stay curious with the motto, “I like what I like.” I have experience playing in a band, where I was a bassist responsible for songwriting and composition. Instruments I’ve performed on include bass, guitar, and piano. I resumed piano lessons after turning 40 and have been continuing ever since!

I started playing guitar in middle school and focused on band activities during my student years. I’ve been a hobbyist Vocaloid producer for over 15 years. After entering the workforce, I gained experience in various roles, including event sound engineering and videography/photography. As a writer, I’ve contributed introduction articles for music and manga websites, and in 2022 I had the opportunity to write the bonus liner notes for IA SUPER BEST. My specialties are Japanese rock, Vocaloid, and manga.

Suddenly, but have you all heard of a music genre called “denpa song,” a culture that developed mainly on the internet in the 2000s?

With hurried beats, vocals laced with exaggerated acting, and lyrics and call-and-response lines that can be extreme and stick in your head—while the definition is fuzzy, denpa songs leave behind many classic (and notorious) tracks with a powerful sound that makes you feel the “denpa.”

Spreading from an underground culture into the mainstream, the spirit of denpa songs continues even in the Reiwa era.

This time, we’re highlighting karaoke crowd-pleasers, focusing on representative classics.

If you’re a younger listener who’s recently gotten interested in denpa songs, be sure to check these out!
