The castle towers, where the lord lived in the castle, are the tallest building. However, after the 17th century, when peace continued, the castle towers have not been rebuilt after it disappeared due to fire.

I stated that there are currently 12 castle towers left before the Meiji Restoration in the middle of the 19th century.

The Imperial Palace, which is now the residence of the Emperor, was Edo Castle, the residence of the Tokugawa Shogunate, before the transfer of the capital to Tokyo in the middle of the 19th century. The castle tower has gone unnoticed after the 1657 fire. At that time, the castle tower was not needed because the Warring States period had already ended and a peaceful era had begun. This castle is not open to the general public.

Nijo Castle in Kyoto has not been rebuilt after the castle tower was destroyed by lightning in 1750. Some people say that it doesn’t look like a castle at all, but there are many attractions such as the national treasure Ninomaru Palace and numerous gardens, making it an attractive tourist destination.
