Things we wish someone had told us before we landed.
Best Seasons: Spring & Autumn
March–May is warm (22–28°C), flowers blooming, pre-typhoon. October–November the sea is still 26°C and crowds thin. Avoid July–September (typhoon season) unless you have travel insurance and flexible tickets.
Car Rental Needed for Days 3–5
Naha is walkable and served by the Yui Rail monorail. North Okinawa and the south (Peace Park, Cape Kyan) require a car. Rent from Naha on day 3 and return on day 5. International Driving Permit required for most visitors.
Book Kerama Ferry in Advance
The Zamami and Tokashiki ferries from Tomari Port sell out fast in March–May and October–November. Book 2–4 weeks ahead. Bring reef-safe sunscreen — chemical sunscreens are prohibited in the Kerama marine park.
Okinawan Food You Must Try
Okinawa soba, goya champuru, rafute (pork belly), taco rice, umibudo (sea grapes), jimami tofu (peanut tofu), Orion beer, awamori (local spirit), beni-imo sweets, and fresh sashimi from Makishi Market.
Understand Okinawa's Complex History
Okinawa was an independent Ryukyu Kingdom until 1879, then a brutal WWII battleground, then US-administered until 1972. The Peace Memorial Park is essential context. The local culture — language, food, music, architecture — remains distinctly Ryukyuan, not mainland Japanese.
Sun Protection is Serious
Okinawa's UV index is extreme (9–11) from March through October. Apply reef-safe SPF 50+ sunscreen, wear a rash guard for snorkelling, and stay hydrated. Heat exhaustion is a real risk for unprepared visitors.
