Hyohō Niten Ichi-ryū (兵法 二天 一流), which can be loosely translated as "the school of the strategy of two heavens as one", is a koryū (ancient school), transmitting a style of classical Japanese swordsmanship conceived by Miyamoto Musashi. Hyōhō Niten Ichi-ryū is mainly known for the two-swordkatana and wakizashikenjutsu techniques Musashi called Niten Ichi (二天一, "two heavens as one") or Nitō Ichi (二刀一, "two swords as one").
