No, the current castle tower is a reconstruction. The original structure was dismantled during the Meiji period in the late 19th century as part of nationwide castle demolitions. The castle tower visitors see today was reconstructed in 1986 based on historical documents, drawings, and archaeological evidence. However, portions of the original stone walls remain, including notable examples of bōzuishi (transferred stones) taken from temple foundations that still bear visible inscriptions and carvings.
