Cape Manzamo juts into the East China Sea near Onna Village on Okinawa's west coast, where the land ends abruptly at a series of coral limestone cliffs rising fifteen metres above the waves. The view is striking at any hour, but the cape is best known for its sunsets, when the sky over the Kerama Islands turns orange behind the distinctive rock arch that extends from the base of the cliffs.
The viewing area is paved and well-maintained, with a walkway along the cliff edge. It is popular and often busy in the late afternoon, but the western orientation means the crowds are at least seeing the same thing you are. The coast here is part of a subtropical coastal nature zone; the low scrub vegetation and eroded limestone are characteristic of this stretch of Okinawa's west coast. Combine with a stop at one of the Onna dive shops if you plan to explore underwater.
