Naitō Jōsō
Naitō Jōsō (内藤 丈草; 1662 – March 29, 1704) was one of the principal disciples of Bashō, and himself also a respected haiku writer in the Genroku period of Japan. Originally, he was a samurai from Owari, but he had to leave military service due to ill health. Taking up the literary life, he became a devout disciple of Bashō, and when the Master died in 1694, Naito mourned him for a full three years, and remained his devout follower for the rest of his life.
