In 1610, the warlord Tokugawa Ieyasu, a retainer of Oda Nobunaga, moved the capital of Owari Province from Kiyosu to Nagoya. This period saw the renovation of Nagoya Castle. Nagoya was proclaimed a city in 1889, during the Meiji Restoration, and became a major industrial hub for Japan. The traditional manufactures of timepieces, bicycles, and sewing machines were followed by the production of special steels, chemicals, oil, and petrochemicals, as the area's automobile, aviation, and shipbuilding industries flourished. Nagoya was impacted by bombing from US air raids during World War II.
