　Kudaka Island in Okinawa is home to just over 200 people and holds a sacred cultural legacy centered on the grand IZAIHŌ festival, celebrated once every 12 years for more than six centuries. The island is renowned for its traditional production of IRABŪ, smoked Erabu sea kraits, revered as a divine gift from the gods and once presented at banquets for distinguished guests of the Ryukyu Kingdom.
