Okinawa's Crystal Clear Blue Sea - Tokashiki Island's 'Kerama Blue'

Tokashiki Island is the largest island in the Kerama Islands National Park and the closest to Okinawa's main island. The island's terrain is rugged, covering an area of about 15 square kilometers. You can take a ferry from Naha to Tokashiki Island, and there are many operators offering day trips online. Some shops offer snorkeling tours that include transfers from the port to Aharen Beach, lunch, and discounts on renting beach chairs and umbrellas from the shop.
