Japanese castles are unique structures that served as fortifications and residences for feudal lords during the Edo period. They are characterized by their wooden construction, intricate designs, and multi-tiered roofs, often adorned with decorative elements. Many castles, such as Himeji Castle and Matsumoto Castle, are recognized for their historical significance and architectural beauty. These castles were strategically built on hills or near rivers to enhance defense against invaders. Today, many Japanese castles have been preserved or restored, allowing visitors to explore their rich history and enjoy panoramic views from their towers. They are important cultural symbols in Japan.
