2. [On-Site Report] Key Highlights & Dad’s Insights
[Highlight 1: The Overwhelming Scale of “Dry Moats” – Different from Hojo and Yuzuki Castles]
Sakura Castle’s main feature is its simple yet massive “dry moats” – a stark contrast to the technical shoji-bori (partitioned moats) of Yamanaka Castle (Hojo clan) or the water moats seen at Yuzuki Castle in Ehime, which I’ve visited previously.
The biggest difference is the absence of water in these moats. You can immediately grasp the depth of the steep slopes extending to the bottom, and I was overwhelmed by their sheer impossibility to climb. Without water to obscure their true depth, the despair inflicted upon attackers must have been immense. Walking through the area with statues of Hotta Masayoshi and Townsend Harris, I truly felt the sheer determination of the civil engineering work that carved out these massive valleys during the Edo period.


[Highlight 2: Tracing Historical Footprints and Discovering City Symbols]
While some aspects of the historical background were a bit complex, my son and I enjoyed exploring like a treasure hunt, searching for uniquely designed manholes on the ground and admiring the statues. In contrast to the ruggedness of Motosakura Castle, Sakura Castle offered the pleasant comfort of a well-maintained park, allowing us to leisurely follow the footsteps of history.
Also, in the “Sakura Castle Visitor’s Notebook (December 29, 2025)” at the Management Center, there’s a drawing left by my son. If you happen to visit, please try to find it!

3. Family-Friendly Guide for Kids & Parents
My Son’s (8 years old) Reaction:
Seeing the well-maintained, expansive grassy lawns, he exclaimed with delight, “We can do anything here!” There was a calm, local atmosphere, with people walking their dogs, and he seemed to be enjoying “the ultimate luxurious park play” rather than a castle siege.
Dad’s Pointers:
This is a “castle ruin,” and there are no reconstructed castle towers (tenshukaku) or other flashy structures. It’s a place to appreciate the topography and the remains of the moats. If you go expecting a grand, flamboyant castle, it might feel more like “a big park.” Unless you’re a serious castle enthusiast or a family who loves playing in open fields, you might find it a little underwhelming. However, it’s easily accessible by car from my wife’s family home in Yotsukaido, and if you bring along some toys for play, it’s an ideal spot for families.
4. Castle Trip Companions (Lunch & Souvenirs)
What We Ate / What We Bought:
We brought a “Pokémon Styrofoam airplane (100 yen)” hidden in my bag. Being able to fly it freely into Sakura Castle’s vast sky without complex moats or trees getting in the way was a unique enjoyment offered by this castle’s simple and expansive layout.
