Overview
This 4.7km causeway runs from Uruma on the main island to four outer isles — Henza, Miyagi, Ikei and Hamahiga. Built on shallow flats rather than raised as a bridge, it keeps you nearly at water level with sea on both sides, an oddly liberating drive. Park at the midway roadside station to take in the bay; beyond lie Hamahiga's creation-deity shrines and Ikei's crystal-clear beach. At low tide, locals clam the flats beside the road.
Opening Hours
Open 24 hours (roadside station roughly 9:00-18:00)
🚇 Getting there
About 1 hour by car from Naha via the Okinawa-kita IC; unreachable by public transport — rental car only.
⏱️ How long to visit
About 1-2 hours; half a day with the islands.
🌅 Best time to visit
Clear mornings near high tide show the best water color — and facing east, it's a sunrise drive classic.
Travel Tips
Also a famed sunrise spot. Weekends draw drivers and cyclists — cross early for the calmest run.
