Himeji Castle or Himejijo has the nickname White Heron Castle thanks to its white elegant appearance, is considered to be Japan's most spectacular. The castle is both a national treasure and a UNESCo World Heritage site. Unlike many other Japanese castles, it was never destroyed by war, earthquake or fire and survives intact to this day though it has had extensive renovation over the years. The first fortifications were completed in the 1400s, and were gradually enlarged over the centuries by the various clans who ruled over the region. The castle complex as it survives today is over 400 years old and was completed in 1609 and altogether there are 80 buildings in the complex.
