Nintama Rantarō (忍たま乱太郎, Nintama Rantarō? lit. Rantarō the Ninja Boy) is a Japanese anime series based on Sōbē Amako's manga Rakudai Ninja Rantarō. It was produced by Ajia-do Animation Works and originally broadcast on NHK. It is aimed at young children, featuring the adventures of Rantarō and his friends and teachers at Ninja school. The fact that glasses are worn by one of the main characters is probably anachronistic. The manga references other Japanese media personalities such as Ken Shimura.
