On April 9th, there was a live music event called Island Music Day in Naha to celebrate music of the islands of Okinawa from Minyo (沖縄民謡: traditional Okinawan folk) to Okinawan salsa.
Here are more stills
and video clips from the concert:
This concert used to be called “the Folk Music Day Concert” to commemorate the day of (contemporary) folk music on April 9th. Although similar events are held on this day all over Japan, but it seems to be more popular in Okinawa, and there are quite a few folk music gigs held throughout the southernmost islands of Japan.
However, the organizer of this event changed it to the island music day seemingly to attract wider audience and also to honor Okinawa’s own folk music.
