Very little is known about the Akutagawa family except that they are one of the many houses of Koga. It is possible that they are related to the Taira and worked for Kamakura Shogunate. There is Akutagawa Style ninjutsu, popularized by either Yoshinori Akutagawa or another. It's said in an antedote that Yoshinori was invited to a feast at Matsumoto Castle to demonstrate his Onibi jutsu. Female maids surround him; after Yoshi chants an incantation, there is a sweet fragrance and the maids' thighs were exposed from under their kimonos.
