Uradome Coast: Spectacular Cliffs and Rock Formations Called the Matsushima of Sanin

A crystal-clear emerald-green sea, rugged rock formations and sea caves carved by the waves, white sandy beaches and coves — the Uradome Coast in Iwami Town, Tottori Prefecture, is a beautiful scenic spot also called the Matsushima of Sanin. As a landscape representative of the Sanin Kaigan National Park and the Sanin Kaigan Geopark, its highly transparent sea and richly varied coastline are best enjoyed up close by sea kayak or sightseeing boat. It is a natural work of art carved by the Sea of Japan.

The Matsushima of Sanin

The Uradome Coast is a scenic spot in Iwami Town in eastern Tottori Prefecture. Sheer cliffs, rock formations, sea caves, and white sandy beaches born from wave erosion continue for about 15 km along this ria coast, and its beauty has earned it the name the Matsushima of Sanin. In 1928 it was designated a National Place of Scenic Beauty and Natural Monument, and it is also chosen among the Hundred Landscapes of Japan and the Hundred Best White Sand and Green Pine Coasts of Japan. As part of the Sanin Kaigan National Park and the Sanin Kaigan Geopark, where you can learn how the earth was formed, this precious terrain is protected.

A Sea of Remarkable Clarity

The sea at the Uradome Coast boasts outstanding transparency. On days with good conditions, the sea floor is visible even where the water is deep. The water shining emerald green and cobalt blue looks like a tropical resort. Swimming can be enjoyed in summer, and its beautiful water quality has been selected among the Ministry of the Environment Hundred Best Swimming Beaches. The contrast between the clear blue sea and the rugged granite rock faces is a beauty that leaves you spellbound.

Sea Kayaking and Sightseeing Boats

To fully enjoy the spectacular scenery of the Uradome Coast, viewing it from the sea is best. On a sea kayak experience, you paddle through the transparent sea at your own pace, passing through sea caves and slipping between rocks to feel the power of the formations up close. For an easier option, the island-tour sightseeing boat is also recommended. It circles the many scenic spots in about 40 minutes, viewed from the water with a guide commentary. Rock formations such as Sengan Matsushima seen from the boat are well worth the trip.

Seasonal Highlights

Early summer through autumn is the best season for sea activities, when you can fully enjoy the highly transparent water. The island-tour boat generally operates from around March to November and does not run in winter. Summer is ideal for swimming and snorkeling, perfect for a trip seeking cool relief. In autumn the sea is calm and the air is clear, making the view from the boat all the more beautiful.

Access and Essentials

Reach it by bus or car from JR Sanin Main Line Iwami Station. It is close to central Tottori City, about 30 minutes by car, and about 10 minutes by car from the Tottori Sand Dunes, making it easy to visit alongside dune sightseeing. The island-tour boat generally runs from around March to November, with a guide price of 1,800 yen for adults and about 40 minutes (closures and fares may change, so check official information). Sea kayaking is often by reservation and varies by operator.

Practical Travel Notes

• Both the sightseeing boat and sea kayaking may be canceled when the sea is rough. Checking the operating status the day before or day of is reassuring.
• For sea kayaking, prepare clothing that can get wet and a change of clothes. Most tours include a guide for beginners and provide equipment.

• If swimming or snorkeling, mind your valuables and footing on the rocks. Marine shoes make it more comfortable.

A Word of Advice

The real appeal of the Uradome Coast is the rock formations and transparent sea viewed from the water.
