Uradome Coast Island Cruise Pleasure Boat

The Uradome Coast Island Cruise Pleasure Boat operates along one of Japan's most geologically significant coastlines within the San'in Kaigan National Park in Tottori Prefecture. The rocky coast consists of 30-60 million-year-old granite formed during the era when the Japanese archipelago was part of the Asian continent, before the Sea of Japan existed. The landscape has been sculpted by the raging waves and harsh weather of the Sea of Japan over unimaginably long periods, creating the dramatic coastal features visitors see today.

The Uradome Coast stretches approximately 15-16 kilometers along the Sea of Japan on the eastern tip of Tottori Prefecture, featuring marine-eroded rock formations, white sandy beaches, and dense scrub pines. The area holds special significance as part of the San'in Kaigan UNESCO Global Geopark, which preserves geological records spanning from Japan's continental origins to the formation of the Sea of Japan. The coastline's complex ria formation and distinctive granite structures make it one of Japan's premier examples of coastal geological evolution.

The 40-minute cruise navigates through narrow passages between small islands and sea stacks that larger vessels cannot access. The crystal-clear waters offer visibility up to 25 meters deep, allowing passengers to observe the submarine landscape. Visitors experience dozens of tunnels, caves, and unusual rock formations wherever the ocean waters flow. Small boats can enter caves and shallow coves that other sightseeing vessels cannot reach. The captains provide commentary while skillfully maneuvering through jagged rocks and close to towering cliffs. Passengers often enjoy feeding seagulls that follow the boats throughout the journey.

The cruise departs from Otani Pier near the mouth of the Gamo River at Ajiro Port, located about 10 kilometers east of the famous Tottori Sand Dunes. Boats operate from 9:30 a.m. until 3:30 p.m., March through November, departing every hour. The departure point is accessible by local bus services from Tottori city center or JR Iwami Station. Visitors should note that sea conditions may affect operations, and the experience can be physically demanding due to ocean swells. The boats accommodate various group sizes, with smaller vessels providing more intimate access to narrow coastal features.
