Flag of Nagoya Aichi Japan - Color Changing Coffee Mug

The Flag of Nagoya, Aichi, Japan, is the official emblem representing this major city located in the Chūbu region on Honshu island. Adopted on March 10, 1948, the flag consists of a white field with three horizontal stripes: red at the top and bottom, and black in the middle. The flag design symbolizes Nagoya's history as a castle town and its development from a feudal domain to a modern city. The upper and lower red stripes represent the historical domains of Owari and Mino, while the central black stripe signifies the merging of these two domains in 1600 under Tokugawa Ieyasu, the founder of the Edo bakufu (Tokugawa shogunate). The flag serves as a symbol of Nagoya's rich heritage and cultural identity within Japan.
