Morning light slices across Naha’s harbor as the boat slips clear of the city’s high-rises and into the open blue, the Kerama Islands appearing like low, green hulls on the horizon. By the time you stretch into your wetsuit on deck, salt air has replaced traffic hum; the guides brief you gently, fitting gear and walking through basic dive safety steps before the first entry.
