Spot guide · Miyakojima 宮古島
Photo: Rsa / CC BY-SA 3.0Opened in 2015 after nine years of building, Irabu Ohashi runs 3,540 metres from Miyako to Irabu island — the longest bridge in Japan that charges no toll. It humps in the middle to let ships pass beneath, which gives the road a rise and fall like a slow wave, with Miyako blue on both sides the whole way.
For the five thousand people of Irabu it ended a life ruled by ferry timetables and weather — the school run, the hospital, the airport all became a road. For a visitor it is the rare landmark where the experience is the crossing itself: nothing to queue for, nothing to buy, just the water and the engineering.
Ten minutes out, cross, one lookout, return — the tightest worthwhile version.
Cross to Irabu and Shimoji, walk 17END if tides are kind, and pair with Maehama or Sunayama.
Take it westbound in the morning light or last in the afternoon — the low sun is the bridge at its best.
Yes — there is a walkway and cyclists cross regularly, but respect the scale: 3.5km each way with a climb over the shipping hump, no shade, and real wind. Most port-day visitors cross by car and walk the lookout ends instead, which delivers the same views for a fraction of the clock.
At low tide, emphatically — the lagoon beside the Shimojishima runway drains to a white sandbar in impossible water. The road to it is closed to vehicles, so you park before the gate and walk about fifteen minutes. Check the tide before committing a short call to it.
