A Ryukyu chain of parks and limestone: Kerama National Park, Ishigaki manta water, the Blue Cave at Cape Maeda, and a temperate-to-subtropical season. Okinawa Prefecture is a Ryukyu island chain southwest of mainland Japan whose recreational water includes Kerama Islands National Park (2014), Ishigaki's manta sites, the Blue Cave at Cape Maeda on the main island, and remoter Miyako and Yonaguni options.
Wow factor is high for a Japanese prefecture, a step below equatorial places in this atlas. Accessibility is middling-high: domestic flights and a few shore entries (Maeda), plus boats that wait on wind. Seasonality is moderate-high: a summer mass window and a winter that is still a wetsuit. Risk is moderate: cave overhead at Maeda, current at Kerama and Ishigaki, not wreck-penetration scores.
Check each criteria to confirm findings against the atlas verdict.

This chapter is a place atlas, not a certifying agency, not medical advice, and not a live briefing. Japan Coast Guard, national-park rules and the day's wind override any sentence here. A national park (2014) west of Naha, known for clear water, turtles, and boat snorkel/scuba. Zamami is a common gateway island.
Boat sites such as Manta Scramble / Kabira-area points where manta rays are seen in season. Distance rules apply. Not a first Maeda day. Japan's westernmost inhabited island, famous for a submerged rock formation and strong current. Advanced, remote, optional. This page is not a monument theory essay.
This is a reading check for the atlas, not personal advice, a live price, or a booking. It does not replace the full topic page.
