The main keep consists of three stories with a triple-layered roof. The roof features a diverse arrangement of "kirizuma hafu" (gabled roofs), "irioya hafu" (hip-and-gable roofs), and "karahafu" (Chinese-style roofs). Additionally, the second and third floors are adorned with "katōmado" (flower-headed windows), and the third floor showcases a "mawari-en" (surrounding balustrade), placing emphasis on the exterior appearance and presenting a beautifully varied silhouette.
