A blue roof of sky and an ocean so clear you can read the reef from the boat — this is the opening frame of a Kerama Islands day trip. Departing Naha, the boat slips across turquoise lanes toward Zamami, Tokashiki, and the smaller isles; the wind tastes faintly of coral and salt. Dive instructors brief the group on deck, hand over masks and regulators, and guide even first-timers through surface practice before the controlled descent.
