Hakkō-ryū (八光流) or Hakkō-ryū Jūjutsu (八光流柔術) is a school or 'style' of jujutsu descended from Daito-ryu founded in 1941 by Okuyama Ryuho (1901–1987) a student of Sokaku Takeda and a practitioner of shiatsu. This style of self-defense focuses on the qi meridian points sensitive to pain so that a defender can create sharp distracting pain to an attacker but without causing serious injury to the person, and it can therefore be considered a humanitarian martial technique.
The school is now headed by his son who inherited the name Nidai Soke Okuyama Ryuho. The headquarters or honbu dojo is located in Ōmiya-ku, Saitama, Saitama Prefecture.
