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.

The Koshinetsu and Hokuriku regions are home to expansive, majestic mountains and crystal-clear skies.

Music festivals held here are drawing attention as special experiences where great outdoors and music intertwine.

In addition to performances by renowned artists, these events are packed with attractions like delicious local cuisine, hot springs, and camping unique to this area.

Savor blissful moments as you take in the grand scenery, wrapped in a pleasant breeze and the best music.

GREEN FLASH FesSat, 5/30, Fukui Prefecture

GREEN FLASH Fes is held at a resort facility in Fukui Prefecture, set against the backdrop of the sea. A “green flash” is the moment when a green light appears as the sun sinks into the ocean, and legend has it that seeing it brings good luck. With your favorite music as the soundtrack, it’s an event where participants can spend their time freely—lying on the grass while gazing at the vast sky and ocean, or enjoying delicious food. There’s also a fully equipped campground nearby, so how about adding it to your travel plans?

Nagaoka One Hundred Sacks of Rice FestivalSat, May 23 — Niigata Prefecture

http://www.comefes.net

Around the time of the Meiji Restoration, the Nagaoka Domain, which had been given one hundred bags of rice, chose not to consume them—since they would be gone immediately—but instead sold the rice and used the proceeds to build a school, successfully cultivating human talent. Inspired by this “Spirit of One Hundred Bags of Rice,” we aim to create a future-oriented festival—the most comfortable festival in Japan. Enjoy the ultimate two days of fireworks, food, and music.
