Oomizo Castle

From Jcastle.info



Oda Nobunaga ordered his nephew, Oda Nobuzumi to construct a castle at Takashima to control the western shores of Lake Biwa. The castle was designed by Akechi Mitsuhide. It also functioned as an important port on Lake Biwa. After the Battle of Tennosan in 1582 with the demise of Akechi Mitsuhide, Oda Nobuzumi’s loyalty was called into question, and he was killed by Niwa Nagahide’s troops. After that, Toyotomi Hideyoshi installed one of his generals, Kyougoku Takatsugu as the lord of Oomizo Castle. Takatsugu was also married to Hatsu, one of Asai Nagamasa’s daughters. The castle was downsized to a jinya after the “One castle, one feudal domain” edict.

Visit Notes

There is only the stone base of the castle keep left here. Most of the other structures are long gone. You can see some ishigaki which lined some of the canals. The castle ruin is only 5 minutes walk from JR Omitakashima Station.

I found myself here by chance after visiting nearby Shirahige Jinja, a famous shrine. The castle walls here are slightly interesting, largely made up of natural boulders, it seems.

More interesting than the castle is the Ōmizo Sōmon, a nagaya-mon style gate. This gate was probably built in 1755. The town for the commonfolk and the samurai residence quarter were strictly separated and the Sōmon served as a gateway between the two. Currently there's a small tourist office inside where you can pick up some flyers about the town.

When I visited Ōmizo for the local festival in summer, I came upon a largely unmentioned samurai residence in town. It's not open to the public. It doesn't seem to be in a good state; I'm not sure if there are still people living there. There was a sign outside, though, with some information. To sum up some of the main points: it used to be inhabited by the Kasai Family (笠井家) and the house was changed quite a bit throughout the years. For example, there used to be a nagayamon in front of the house but it was moved a few meters and merged with the genkan of the main building in the Taishō Period.
