Kumamoto Castle is famous as one of Japan's top three castles.
From the gentle slope, the top sudden high stone wall is a stone wall superior in defense that is said to be "crescent moon stone wall" or "warrior overturn".
Kumamoto Castle built over 7 years by Kiyomasa Kato, a master of castle construction, about 400 years ago.
Although the castle tower and many buildings were burnt down during the 1877 Southwest War, they were unable to capture due to the strong defenses of the Sengoku period fortress.
However, due to the 2016 Kumamoto earthquake, about 10% of the stone wall collapsed and about 30% needed to be repaired.
There are 50 places where stone walls have collapsed throughout the castle. Numbered stones are collected and numbered, collated with photographs taken before the earthquake, and the stones are stacked in their original positions. In order to proceed with such delicate reconstruction work, the restoration of the entire castle area will be completed in 2037.
