Tomonaga Sanjūrō was born on March 25, 1871 in Nagasaki, Japan. He was the second son of Tomonaga Jinjirō, a samurai of the Ōmura Domain.
After graduating from Nagasaki Ōmura Junior High School (which is now known as Nagasaki Prefectural Omura High School) and then First Higher School, he entered the Tokyo Imperial University.
After finishing his degree from the same university, Tomonaga Sanjuro became the assistant professor of philosophy at the Imperial University of Kyoto in 1907 and then full professor in 1913.
He mainly lectured on Western Philosophy and the History of Philosophy; and, along with Nishida Kitarō and Tanabe Hajime, constituted the important intellectual movement of modern Japan, i.e., the Kyoto School.
Tomonaga Sanjuro retired from Kyoto Imperial University in 1931 and then became full professor at Ōtani University.
Tomonaga Sanjuro was known for being an unprolific writer but left remarkable works (e.g., "The History of Self-consciousness in relation to the Self of Modernity," "Philosophy from Renaissance to Kant," "Kant's Theory of Peace," and others) and taught many students who later became renowned Japanese philosophers (e.g., Amano Teiyū, Obara Kuniyoshi, Yamauchi Tokuryū, Kosaka Masaaki).
