Niten Ichi Ryu

• Type: Kenjutsu
• Founder: Miyamoto Musashi Fujiwara Genshin (1584 – 1645)
• Era: circa 1640

The name of this style roughly translates as “two heavens as one school” and was developed by Miyamoto Musashi, author of Go Rin No Sho ("Book of Five Rings") and arguably Japan's most famous swordsman. The school dates from the early 1600s and its most distinctive feature is its simultaneous use of both the long and short swords.
