Editor-in-Chief, RAG MUSICHane Keisuke
Editor-in-chief of RAG MUSIC. JFC-certified fact-checker. After working in a music studio and handling wedding sound, joined the RAG MUSIC editorial team in 2016. Experienced with a variety of instruments: marching band in elementary school, clarinet in junior high school wind ensemble, and drums in a band from high school onward. Drawing on my own musical activities and the experience gained through my work, I produce daily articles, including various song introductions, features on music festivals around the country, and live reports. In music, I enjoy not only rock from Japan and abroad but, lately, a wide range of J-pop as well.

Music festivals held across the Kanto region throughout the four seasons continue to captivate the hearts of music fans.

From sophisticated urban venues to lush outdoor stages, these musical celebrations unfold in a wide variety of settings.

Powerful live performances by accomplished artists from Japan and abroad, as well as exciting up-and-coming indie bands, promise encounters with a rich diversity of music.

Why not create special memories at Kanto’s music festivals, each one to be enjoyed alongside the changing seasons—spring, summer, autumn, and winter?
