Its rich waters have nurtured fertile soil and abundant greenery.

The Changing Seasons in Ozu Castle Town
The Hiji River, an important first-class river flowing through Ozu,
is said to derive its name from the many bends resembling a bent elbow.
The river’s graceful curves have nurtured the Ozu Basin, bringing abundance to the region.
For centuries, the people who lived along the Hiji River have depended on its flow as the source of life,
a reminder of time’s eternal passage.
Spring is dawn, summer is night,
Autumn is dusk, winter is early morning
As renowned poet Sei Shonagon wrote in “The Pillow Book,” the early mornings of winter in Ozu are the best time to experience the town.

Hijikawa Arashi, morning mist flowing through the Ozu Basin
Near the mouth of the river in Nagahama, a natural phenomenon occurs when the air trapped in the basin turns into morning mist, flowing upriver.
From autumn through winter, this mist roars like a dragon, engulfing the town.
A rare and miraculous encounter with the “dragon of the Hiji River.”

The morning mist winds through the red Nagahama Bridge and flows out to sea. This mystical sight can be seen from the observation park overlooking the river mouth from a small hill, particularly from October to March when the weather conditions are just right.
The Sea of Clouds Embracing the Castle Town
Another iconic winter sight in Ozu is the Sea of Clouds.
To witness it, venture out early from your lodging and climb a nearby hill.
From late autumn to winter, you can see a sea of clouds stretching out across the landscape,
with mountain peaks poking through like islands.
The sight of your breath turning white against the grand expanse of white clouds is a humbling reminder of nature’s grandeur,
a spectacle that evokes admiration.
This phenomenon occurs when there is a significant temperature difference between day and night and on calm, windless days.
From October to March, the view spans from sunrise until the sun fully rises.
