A getaway to an island — no matter how big or small — should be on any good travel itinerary. Make your escape complete by heading to Senaga Island and spending time by the water.
You'll need to make your way to Tomigusuku to reach this water-surrounded land mass. If you plan to do some sightseeing when you're done, why not stop by Kokusai Dori? It won't take long to get to from Senaga Island.
