NHK revealed a promotional video and theme song information on Monday for the 30th series in the Nintama Rantaro anime franchise.
The anime will premiere on NHK Educational on April 4, kicking off a 30th anniversary celebration for the franchise.
The manga inspired the Nintama Rantaro television anime in 1993, and NHK’s E-tele channel is still airing the 10-minute anime every weekday, including the current 29th series.
As elementary students, Rantarō and his ninja-in-training friends are called “Nintama” — a contraction of the words “ninja” and “tamago” (“egg”).
