Nishi-no-Maru Okura Shōhōkan (West Bailey Storehouse Museum)

🏛 Overview
Located within the Nishi-no-Maru area, the Nishi-no-Maru Okura Shōhōkan is a museum and archive built to replicate the exterior of two Edo-period rice storehouses, Sanban-gura and Yonban-gura.

Nishi-no-Maru (West Bailey)

🏛 Overview
The Nishi-no-Maru area, situated to the west of the main compound, served a crucial role during the Edo period as both a defensive zone and a logistical hub for food storage. Six rice storehouses (Ichiban-gura to Rokuban-gura) once stood here, forming the castle’s primary granary complex.
After the 1891 Nōbi Earthquake, the area’s gate (Enokida-mon) was severely damaged and later rebuilt, eventually becoming the Main Gate of Nagoya Castle. In 2021, the Nishi-no-Maru area gained new significance with the opening of the Okura Shōhōkan.

The Kaya Tree of Nagoya Castle

🏛 Overview
Standing tall in the Nishi-no-Maru area is the Kaya Tree, a colossal conifer estimated to be over 600 years old. Designated a National Natural Monument in 1932, this tree predates the construction of Nagoya Castle and has borne silent witness to centuries of history.
Miraculously, it survived the 1945 Nagoya air raid that destroyed much of the castle. Legend holds that during the Siege of Osaka, Tokugawa Yoshinao—the first Lord of the Owari Domain—ate fruit from this very tree for good luck, earning it the title “Tree of Victory.”
