The 1891 Mino–Owari earthquake in October 1891 (Meiji 24) seriously damaged the southwest and "Tamon" turrets and other structures. Reconstruction and repair work followed, but not everything was rebuilt. In 1893 (Meiji 26), the castle was transferred to the Imperial Household Ministry and in June its name was changed to "Nagoya Detached Palace" or when the castle was designated as a formal imperial residence. On May 20, 1906 (Meiji 39), the grounds were opened to the public for one day for the National Railroad Five Thousand Miles Celebration. In March 1910 (Meiji 43), bronze "shachi" brought from Edo Castle were added to the roofs of the small keep and corner turrets. In February 1911 (Meiji 44), the former Hasuike Gate of Edo Castle was transported and reconstructed on the remains of the Nishinomaru-Enoki Gate, which today is used as the main visitors gate. In 1923 (Taishō 12), the southwest turret was repaired.
