Shinobi no Mono

Shinobi no Mono (忍びの者) is a series of jidaigeki novels written by Tomoyoshi Murayama originally serialized in the Sunday edition of the newspaper Akahata[1] from November 1960 to May 1962.

Set during Japan's Sengoku period, the novels depict Goemon Ishikawa, a famous outlaw hero who was boiled alive at the end of the 16th century by order of Hideyoshi Toyotomi, as a ninja who fought against samurai warlords.

Between 1962 and 1966, a series of eight Shinobi no Mono films (aka Ninja, a Band of Assassins, aka Ninja Spy) starring Raizo Ichikawa were produced and released by the Daiei Motion Picture Company.

* Following the death of series lead Raizo Ichikawa in 1969, Daiei attempted to revive/continue the series with a 9th film entitled 忍びの衆 Shinobi no Shū (Ninja Spies) starring Hiroki Matsukata, who also replaced Ichikawa in their other popular series Nemuri Kyoshiro.

[3] The novels were also adapted into a 52-episode television series starring Ryuji Shinagawa and co-produced by the Toei Company and television network NET (now known as TV Asahi) and broadcast from July 24, 1964 to July 30, 1965.
