- Kōka is historically one of the two primary centers of Japanese ninjutsu, with the local Koga-ryū style emphasizing medicinal knowledge and survival tactics alongside martial skills.
- The city was formed in 2004 through the merger of seven smaller towns within the Kōka District, unifying areas with distinct local histories and castle legacies.
- The region is renowned for the production of Shigaraki ware, a style of Japanese stoneware that is one of the Six Ancient Kilns of Japan, characterized by its reddish-brown color and ash glaze.
- During the Sengoku period, the Kōka region was unique for being governed by a confederation of local clans rather than a single feudal lord, a system known as the Koka-gun-chu.
- The city's topography is defined by the Suzuka Mountains to the east, which historically served as a natural defensive barrier against external incursions.
