Okinawa's Ryukyu Kingdom Heritage: Why It Doesn't Feel Like the Rest of Japan

For centuries, Okinawa was the Ryukyu Kingdom, an independent trading state with its own language and close tributary ties to China, only formally annexed as a Japanese prefecture in 1879. Shuri Castle in Naha was its royal seat; the site has been rebuilt more than once, most recently after a 2019 fire, so check the current state of restoration before visiting, since parts may still be under repair.

The 1945 Battle of Okinawa was one of the Pacific War's bloodiest, with huge civilian losses, and it shaped the island's postwar identity in a way distinct from mainland Japan's wartime memory. Peace Memorial Park, in the south, is a sober, worthwhile stop that lays this history out directly.

Okinawan cuisine is its own thing: goya champuru (stir-fried bitter melon), rafute (braised pork belly), and Okinawa soba are all distinct from mainland dishes, and awamori is the local spirit rather than sake. The climate is subtropical, and the pace of life is famously slower — locals half-joke about 'Okinawa time' running behind the mainland's schedule.
