Number 4: Matsumoto Castle
Matsumoto Castle (松本城, Matsumotojō) is one of the most complete and beautiful among Japan's original castles. It is a "hirajiro" - a castle built on plains rather than on a hill or mountain. Matsumoto Castle is unique for having both a secondary donjon and a turret adjoined to its main keep. The castle structures, in combination with their characteristic black wainscoting, give off an air of grandeur and poise.
