Spring Music Festival Schedule Overview [2026]

In our “Free Music Festival,” the word “free” embodies three meanings: free of charge, freedom, and freedom from various boundaries. It’s a festival where artists of diverse genres perform, offering enjoyment across generations and opportunities for new discoveries.

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?

This is a music event that began after comedian Egashira 2:50 planned and announced it on his official YouTube channel. Egashira is active in many fields, but this time he’s taking on a surprising new challenge: organizing a music festival himself and even negotiating the casting directly. No one can predict what it will be like, so it would be a shame not to take part. You also won’t want to miss the lineup announcement to see which artists will gather.

This festival is being held out of the organizer ADAM at’s desire to spread instrumental music further and to let more people know about Hamamatsu, the “city of instruments” that thrives on the musical instrument industry. An instrumental music festival is pretty rare, isn’t it? Why not take this opportunity to check it out?
