Nagoya Castle is a large castle complex in Nagoya, with a spot outside where visitors can view the main keep. The Hommaru Goten, where lords and retainers stayed, is open for viewing inside, showing gold decorations and rooms. The castle opens at 9 a.m., and visitors remove their shoes to enter the Hommaru Goten. Samurai and ninja role-play takes place at set times. Entry to the main keep has been restricted since 2018 due to safety issues.
