Top 5 Things to Do on Irabu Island
1. Irabu Ōhashi Bridge｜A Spectacular Drive Over the Miyako Blue Sea
Irabu Ōhashi Bridge (Irabu Ōhashi) is a 3,540 m bridge connecting Miyako Island and Irabu Island.
It’s known as Japan’s longest toll-free bridge.
After it opened, travelers no longer needed to rely mainly on ferries—Irabu Island became accessible by car.
Highlights
- Drive above emerald-green water for a true “Miyako Blue” view

The bridge rises higher near the center to allow large ships to pass, creating a distinctive up-and-down driving feel.
Stopping or parking on the bridge is prohibited, so take photos from the parking areas and viewpoints at either end.

Features
