Miyamoto Musashi's early two-sword school
Enmei-ryū (円明流) is a school of Japanese swordsmanship founded by Miyamoto Musashi (c. 1583–1645) before he formulated the two-sword tradition later known as Niten Ichi-ryū. Unlike that better-known school, Enmei-ryū also took in techniques beyond the sword, including the throwing of the short sword and dagger.

Transmission through the domains
Enmei-ryū was carried through the Edo period in several domains, among them Owari, Okazaki and Tatsuno, where it was handed down as a distinct line of Musashi's teaching. A separately transmitted school of similar name, the Musashi Enmei-ryū of the Tottori domain, differs markedly in its forms and technique, and though both descend from Musashi they should not be treated as one school.

Legacy in the Musashi tradition
The domain lines of Enmei-ryū were transmitted into the closing years of the Edo period, but the branch does not survive as a prominent independent tradition today. Musashi's two-sword swordsmanship lives on chiefly through Hyōhō Niten Ichi-ryū, the school with which his name is now most closely associated in Japan.
