Tendō-ryū

, also known as , is a koryū (school of traditional Japanese martial arts) founded in 1582 by Saito Hangan Denkibo Katsuhide. The current headmaster (as of 2020) is the 17th sōke Kimura Yasuko.

Although Denkibo was already an incredibly talented Samurai, he felt that his technique was still incomplete and went to the Tsurugaoka Hachiman Shrine in Kamakura to pray for 100 days. In 1581, Denkibo had the revelation he had been longing for and created his school named Ten Ryū (天流), the “School of Heaven”, which later became Tendō Ryū (天道流), the “School of the Way to Heaven”.
