Ueda City is drawing attention now thanks to the TV drama series Sanadamaru. Ueda Castle is known as the impregnable castle that twice repelled attacks by the opposing Tokugawa clan army. Sanada Shrine, inside Ueda Castle, known as the “shrine that prevents failure”, is a popular place for school students to pray for academic success. Closely related to the Sanada clan of Ueda was the Uesugi clan. In Joetsu City, Niigata Prefecture, home of clan leader Uesugi Kenshin, there is a place one must visit to pray for success.
