Address: Kouri Island, northern Okinawa, Japan

Kouri Island is a compact, low-lying island linked to Okinawa by a single bridge that makes it a convenient day-trip destination from the main island. The shoreline has stretches of sand, rocky outcrops and shallow coral reefs, which give the sea its clear blue-green color on calm days. Vegetation is typical subtropical coastal scrub rather than dense forest, and the island feels exposed and breezy at most times.

Historically the island is one of many small islets around the Okinawa coast and is visited more for scenery than history; modern access by bridge transformed it into an easy stop on drives around the Motobu-Northern Okinawa area. Visiting is straightforward: most people come for a few hours to walk viewpoints, take photos from the bridge, swim or snorkel when conditions are calm, and sample small cafés or food stalls. Facilities are modest and the island can be busy in high season, so expect a relaxed but simple island experience.

  • Kouri Bridge viewpoint: The bridge itself makes a dramatic foreground for photos, with long sea views in both directions and parking/viewing spots near the island ends.
  • Heart Rock: A naturally weathered rock formation shaped like a heart on the shore, popular with visitors for photos and short walks along the coastline.
  • Beaches and shallow reefs: Small sandy bays and exposed reefs offer calm water for paddling and snorkeling when the sea is quiet.
  • Coastal viewpoints: Short walks along the island’s edges reward visitors with low cliffs, rocky outcrops and uninterrupted ocean panoramas.
  • Local seaside stalls and cafés: A handful of small food stalls and cafés near the bridge serve snacks and light meals, making it easy to combine sightseeing with a refreshment stop.

Getting There & Around

How to Get to Kouri Island#

The island lies off the northern shore of Okinawa Island near the Motobu area and is reached from towns on the northern coast; the most common approach is by car. The main international gateway for Okinawa is Naha Airport on the south of Okinawa Island; from there expect around 1.5-2.5 hours by road depending on traffic to reach the northern coastal towns. There is no rail link to Okinawa’s northern coast, so the practical options for the last stretch are a rental car, taxi or local bus to the Motobu/northern coast, then crossing the bridge by vehicle or bicycle and walking from the bridge parking areas to the island’s viewpoints.

Tips for Visiting Kouri Island#

  • The bridge and viewpoint areas are exposed with little shade, so bring sun protection and water. Check sea and weather conditions before planning swimming or snorkeling, as currents and waves can change quickly. The island is best enjoyed as a short stop or half-day trip rather than an overnight destination. Expect modest facilities and limited parking at popular times; arrive early or later in the afternoon to avoid the busiest periods.
