Why Okinawa — and why island-hop?
Okinawa is not a single island — it's an archipelago of over 160 islands stretching nearly 1,000km southwest from the Japanese mainland. The three main island groups — the Kerama Islands, the Miyako Islands, and the Yaeyama Islands — each have a distinct character, and travelling between them is half the experience.
The Kerama Islands offer the clearest water in Japan. Miyakojima has the bridges and the beaches. Taketomi is a preserved Ryukyuan village where buffalo carts still run the coral-walled lanes. Ishigaki anchors the Yaeyamas with its diving, its food, and its connections to the surrounding outer islands. This itinerary uses a logical west-to-east arc, taking in all three groups on a single trip.
October is the finest month: typhoon season has largely passed, water temperature stays at 26–28°C for snorkeling without a wetsuit, visibility hits 30–40m on the outer reefs, and the summer crowds have evaporated. Manta rays arrive reliably at Ishigaki's Manta Scramble from October through March.
Best time to visit Okinawa
October–November is the peak window: typhoon season ends, water stays warm, crowds dissolve, and dive conditions reach their annual best. Manta ray season begins in October at Ishigaki's Manta Scramble — one of the most reliable manta encounters in the world.
March–April is a secondary sweet spot before the rainy season: cherry blossoms in Naha, warm water, and fewer tourists than summer. Water clarity is excellent but slightly cooler (22–24°C).
July–August is peak domestic summer — Japanese families fill the beaches and accommodation prices spike. Still worth visiting, but book everything months ahead and expect crowds at popular snorkeling spots.
May–June (rainy season) and September carry genuine typhoon risk — Okinawa sits directly in the main typhoon track. Travel insurance with cancellation cover is strongly recommended for any Okinawa trip, but particularly in these months.
Six islands, island by island
Listed in recommended arc order — west to east through the Yaeyamas.
The Kerama Islands are where the Okinawa trip begins in earnest. "Kerama Blue" is a local phrase for the colour of the water here — a clarity and intensity that has to be seen to be believed. Zamami is the largest of the inhabited Keramas, with a small village, excellent bike and scooter rental, and direct access to Ama and Inō beaches for snorkeling over coral gardens. The uninhabited Aka Island is a 10-minute ferry away and home to Nishibama — one of Okinawa's finest beaches. October water temperature: 26–28°C, no wetsuit needed.
After the quiet of Zamami, Onna Village offers the Main Island's finest stretch of resort coast — a run of beaches facing west into coral-rich water, with Sesoko Island accessible via causeway to the north. The drive north from Naha via Hamahiga Island adds an unhurried scenic transition. Onna is the right base for exploring the central and northern Main Island — close enough to Naha for a half-day city visit, far enough removed to feel like a proper coastal stay.
Miyakojima's claim to fame is its water — some of the clearest in the world, with visibility regularly hitting 40m+. The island is flat enough to circuit by car in a day, but the bridges alone are worth the flight: Irabu Bridge (Japan's longest toll-free bridge at 3.5km) and Kuruma Bridge over shallow turquoise flats make for extraordinary driving. Yonaha Maehama Beach — 7km of unbroken white sand — is consistently ranked Japan's finest beach.
Taketomi is Okinawa's most extraordinary overnight — a preserved Ryukyuan village where time genuinely feels suspended. Red-tiled roofs, shisa guardian lion statues, and coral-stone walls line every lane. No cars are permitted for visitors; bicycles and water buffalo carts are the only transport. At night, with zero light pollution, the stargazing is extraordinary. One night here is worth the logistical effort — book 3–4 months ahead for October, especially the traditional ryokan options.
Ishigaki is the largest and most developed of the Yaeyama Islands — a proper town with excellent restaurants, a night market, and ferry connections to seven surrounding islands. The main attractions are underwater: Kabira Bay (glass-bottomed boat tours over black pearl beds), Yonehara Beach reef, and the famous Manta Scramble — a dive site where manta rays aggregate in channels from October through March with near-guaranteed sightings. The town itself has the best Yaeyama soba, fresh tuna, and local sake in the archipelago.
What to know before you go
⛴ Ferry Logistics
The Queen Zamami ferry from Tomari Port (Naha) to Zamami runs around 3 times daily but fills fast on weekends — book online at zamami-son.com in advance. Taketomi ferries (Yaeyama Kanko) run every 30 minutes and need no booking. Inter-island flights should be booked 4–6 weeks ahead for October travel.
🚗 Getting Around
A rental car is essential on the Main Island and Miyakojima. Book an automatic well in advance — stock is limited. Taketomi has no rental cars for visitors (bicycles only). Ishigaki is a mix of rental car, taxi, and bus depending on your accommodation location.
🤿 Diving & Snorkeling
October is peak diving season across all three island groups. Manta rays arrive at Ishigaki's Manta Scramble reliably from October. Visibility hits 30–40m on Miyako's outer reefs. Book dive tours the evening before at your accommodation — most guesthouses can arrange directly with local operators.
💴 Cash & Cards
Many guesthouses on Zamami and Taketomi are cash-only. Carry at least ¥30,000 for the Zamami leg and ¥15,000 for Taketomi. 7-Eleven ATMs accept foreign cards everywhere on the Main Island and Ishigaki. Taketomi has no ATM — withdraw before the ferry.
🌊 October Conditions
Water temperature 26–28°C — comfortable without a wetsuit for all-day snorkeling. The rainy season is long over and visibility is excellent. October is typhoon season's tail end — have a 1-day buffer in your schedule if possible, and keep travel insurance that covers natural disruptions.
✈ Flights to Book
Main hop: Tokyo/Osaka → Naha. Then: Naha → Miyako (55 min) and Miyako → Ishigaki (40 min). October weekends book out early on all domestic legs — book flights before accommodation.
