Parque de Ondo no Seto, Kure, Japón

Ondo no Seto Park is located in Kure City, Hiroshima Prefecture, overlooking the Ondo Strait, a narrow waterway separating Kurahashi Island from the mainland. The park was established to showcase this historically and geographically significant channel, which measures only 90 meters at its narrowest point. The strait has served as an important maritime route since ancient times, and the area gained strategic importance during the Edo period when the Hiroshima Domain controlled shipping through these waters. The construction of the Ondo Bridge in 1962 connected Kurahashi Island to the mainland, transforming local transportation.

The Ondo Strait is renowned for its dramatic tidal currents, which can reach speeds of 10 knots during peak flow. This natural phenomenon occurs due to the extreme narrowness of the channel combined with significant tidal variation in the Seto Inland Sea. The rushing waters create visible whirlpools and turbulent patterns that have fascinated observers for centuries. The park provides one of the best vantage points for witnessing these powerful currents, which reverse direction approximately every 6 hours with the changing tide. The area is part of the Setonaikai National Park, Japan's first designated national park established in 1934.

Visitors to Ondo no Seto Park can observe the tidal currents from elevated viewing areas and walking paths that offer clear sightlines across the strait. The observation deck provides interpretive displays explaining the tidal mechanics and local maritime history. The park includes rest areas and benches positioned for extended viewing of the water patterns below. Photography enthusiasts visit to capture the dramatic water movements, particularly during maximum tidal flow. The park's positioning allows views of both the historic Ondo Bridge and the modern Kurahashi Ohashi Bridge that spans the strait nearby. Cherry trees planted throughout the park attract visitors during spring bloom season.
