Hijikawa Arashi is a rare natural phenomenon that occurs when fog formed in the Ozu Basin upstream flows rapidly along the Hiji River toward the estuary, accompanied by strong winds. This spectacular event is characterized by roaring winds that can cause the fog to stretch several kilometers offshore, with wind speeds exceeding 10 meters per second near the river's mouth.

This winter spectacle typically occurs from around October to March but is only visible when specific weather conditions align. On days without strong land winds, the phenomenon can also be enjoyed as a sea of clouds. However, when the fog surges down the river like a massive, undulating wave, the sight is akin to a mystical white dragon descending toward the sea.
Although it is a rare and elusive phenomenon, visitors can refer to forecasts provided by the local "Hijikawa Arashi Forecasting Association.” For optimal views, the "Hijikawa Arashi Observation Park" and "Nagahama Bridge" are recommended vantage points.

You can enjoy the view from the "Hijikawa Arashi Observation Koen (Park)" or the "Nagahama Bridge."
