Zezé Castle Ruins Park

A Fortress of Peace on the Water: Savoring a Silent “Blue Moment” at Zeze Castle Site Park

You have walked the vibrant Shijo Street of Kyoto and offered your prayers at the glittering Yasaka Shrine. While your heart may dance to that splendor, do you ever find yourself longing to leave the tourist crowds behind? Do you wish to blend in with the locals and quietly gaze upon the true, unadorned beauty of Lake Biwa?

If so, journey to Zeze Castle Site Park, located on the shores of Otsu City, Shiga Prefecture—just 15 minutes by train from Kyoto. This is the former site of a “Water Castle,” built by Tokugawa Ieyasu with a prayer for great peace throughout the land. Today, it serves as a hidden sanctuary where the lake breeze and the scent of history intertwine, known only to those truly in the know.

1. Memories of the “Water Fortress” Imagined by Tokugawa Ieyasu

As you step into Zeze Castle Site Park, the first things to catch your eye are the powerfully stacked stone walls and the beautiful, white-walled reconstructed gate.

In 1601, following his victory at the Battle of Sekigahara, Tokugawa Ieyasu ordered a castle to be built here as a strategic key to protect the east of Kyoto. The most distinctive feature of this castle was that it was a Mizujiro (Water Castle), with most of its structure jutting out into Lake Biwa.

While Nijo Castle in Kyoto symbolized the “Authority of the Shogun,” Zeze Castle possessed the dignity of a “Guardian of the Lake.” Although the original buildings no longer stand, the way the lake water laps right up against the stone walls surrounding the park vividly conveys the image of a “Castle Floating on Water.” Sitting atop the remnants of the castle walls, the prayer for peace that Ieyasu entrusted to this lake feels as though it reaches you through the gentle sound of the waves.

2. A Portrait of Lake Biwa Painted by the Four Seasons

Zeze Castle Site Park is also a place where the local people of Otsu feel the beauty of the seasons most closely.

Spring: Pink Clouds Gracing the Lake Hundreds of cherry trees are planted within the park. In spring, a breathtaking view unfolds, weaving together the stone walls, the blue lake, and the pale pink blossoms. Unlike the famous, crowded cherry blossom spots in Kyoto, you can spread out a mat and enjoy a luxurious time under the flowers at your own pace.
Summer: A Contrast of Cool Breezes and Blue On summer afternoons, the wind blowing off the lake cools your skin. The endless blue sky and the sight of yachts and the paddle-wheeler “Michigan” gliding across the water make this the ultimate spot to escape the stifling heat of the Kyoto basin.
Autumn and Winter: Translucent Silence In the crisp air of autumn and winter, you can see clearly all the way to the mountains on the opposite shore. At dusk, the beauty of the “Blue Moment”—when the lake surface shifts from orange to a deep purple—is so profound it leaves you speechless.

3. A Moment of “Mindfulness” Where History and Daily Life Intersect

The greatest charm of this park is that while it is a historical site, the “daily life” of people flows through it naturally.

You will see people walking their dogs, students lost in books on benches, and musicians practicing their instruments toward the lake. If the temples of Kyoto are “perfected spaces for appreciation,” Zeze Castle Site Park is a “free space where people breathe alongside history.”

Standing at the tip of the park (the former site of the inner bailey), nothing obstructs your view. A 180-degree panorama of Lake Biwa stretches before you, with the Omi Great Bridge visible in the distance. Taking a deep breath here allows the fatigue of travel to dissolve, reminding you that you are a part of nature itself. This is the “true luxury” known only to locals, found in no guidebook.

4. Travel Advice: A Lakeside Escape to Forget the Everyday

For those afternoons when you think, “I have fully enjoyed Kyoto’s traditional culture, but today I want to relax and touch the local lifestyle,” Zeze Castle Site Park is your ideal destination.

Tracing the Roots of the Castle Gates: Interestingly, after Zeze Castle was dismantled in the Meiji era, several of its gates were moved to nearby shrines and temples (such as Omi Jingu and Zeze Shrine) and still exist today. For history buffs, exploring the town to find these fragments of the former castle makes for a fascinating adventure.
Lakeside Walking Path: The promenade stretching from the park along the lake is an excellent walking course. Watch the locals enjoy fishing as you walk along the horizon that seems to go on forever.
A Picnic Recommendation: Pick up some local ingredients at a nearby bakery or market and have a picnic on the park’s lawn. A lunch while gazing at Lake Biwa will be a memory that rivals any high-end restaurant.

Conclusion: Finding Waterfront Serenity Next to the Ancient Capital

A trip through Kyoto is a journey to know the “Depths of History.” A trip to Zeze Castle Site Park is a journey to touch the “Serenity of the Water.”

Just minutes from the thousand-year-old capital, you can gaze upon the same view that Tokugawa Ieyasu likely loved while feeling the breeze of Lake Biwa. That peaceful time will surely become one of the most cherished “blue memories” of your trip to Japan.
