Hirosaki Castle (弘前城 Hirosaki-jō?) is a hirayama-style Japanese castle constructed in 1611. It was the seat of the Tsugaru clan, a 47,000 koku tozama daimyō clan who ruled over Hirosaki Domain, Mutsu Province, in what is now central Hirosaki, Aomori Prefecture, Japan. It was also referred to as Takaoka Castle (鷹岡城 or 高岡城 Takaoka-jō?).
