Kumamoto castle is one of Japan's leading sightseeing spots. It is counted as one of the three best castles in Japan, and its beauty and grandeur are worth seeing. The castle was built in 1607 at the beginning of the edo period, more than 400 years ago. It was created by kato kiyomasa (1562-1611), a warlord from owari (present-day western aichi prefecture). "Mushagaeshi," which has become a synonym for kumamoto castle, seems to be gentle and easy to climb up, but the more you go up, the more it warps and you can't climb up. Not only the samurai, but even the nimble ninja can't climb. Don't miss the uto turret, the only multi-tiered turret that retains its original appearance. It is a turret with 3 layers, 5 stories and 1 basement, and about 19 meters above ground, built on the 20 meter high stone wall in the northwest corner of the honmaru, and boasts the structure and size of the castle tower. The roof of uto yagura is topped with shachi (orca), and it is sometimes called the "third castle tower" along with the big and small castle towers. Kumamoto castle was severely damaged by the 2016 kumamoto earthquake, but the "kumamoto castle special opening" is now open for visitors to observe the damage and restoration work. From the special observation passageway which is about 6 meters above the ground, you can see the appearance of the castle tower which includes two types of stone walls with different ways of piling stone walls and two types of stone walls at the same time, the damage condition of the continuous masugata from takenomaru to iidamaru, and the important cultural property turret of higashi takenomaru You can see the groups. The construction work will continue toward full restoration, but why not enjoy the appearance of kumamoto castle that can be seen only now and touch its magnificent history of over 400 years?
