The ruins of present-day Guinin Castle in northern Okinawa, Japan, are one of the World Cultural Heritage Sites and a relatively well-preserved ruin.
There are nine ruins in Okinawa (including Shuri Castle), commonly known as the "Heritage Complex of the Ryukyu Kingdom".
Although only the ruins are visited now, without a single building, according to the scope of the stone city wall and foundation, it is difficult to imagine the scale of that time.
At the right time, you can also see a little cherry blossoms, and because of the sea, you can overlook the beautiful sea view.
