Kumamoto Castle () is located in the central area of Kumamoto City, Kumamoto Prefecture, Japan. It is one of Japan's famous attractions and a special national historical site of Japan. It is a Pingshan City. It has many buildings such as pavilions, Tianshou Pavilion, Sui (City Building), wells, stone walls, etc. The city is 5.3 kilometers long and is called the three famous cities in Japan together with Himeji Castle and Nagoya Castle. When Kato was building the city, he considered that there was a need for food supply in the city during the siege. Therefore, Ginkgo biloba was planted to prepare food for war, so it was also known as Ginkgo City. It was discovered by the Kato Shrine in front of Kumamoto Castle that Kumamoto Castle is still not open to the public so far. As the castle city of Kumamoto Castle, it is still daunting. In fact, if it wasn't for Kato's seven years of time to cite the most advanced method of building the city at the time, I am afraid that what we saw today is really only the ruin. . Since the road to the main city has been closed, the Kato Shrine is currently one of the best places to photograph the main city castle tower or take a group photo. Visitors who come to see Kumamoto Castle and the shrine every day are constantly coming.
