The Little Kaiju Cheering Everyone’s “First Step”! ULTRAMAN’s Newest Project “KAIJU STEP” Will Now Officially Start Theme Song by “Keropons”! Picture Books, Short Anime and Other Fun Projects Will be Announced

Nov.01, 2018


Tsuburaya Productions Co., Ltd. (Head office: Shibuya, Tokyo. President and CEO: Takayuki Tsukagoshi) is starting its newest ULTRAMAN project “KAIJU STEP”, which cheers on the “first step” of all children.

(Special Website:



The Kaiju of the ULTRAMAN series, are not just enemies defeated by the heroes. Each has their own special powers, looks, and characteristics which make them all unique. These characters are popular along with the Ultra Heroes.

The main characters of “KAIJU STEP” are the “little Kaiju”. The characters are designed as though the popular Kaiju in the ULTRAMAN series have become little kids. The story is set in the “little planet” where the unique “little Kaiju” try new things, meet new friends and portray each of their little “first steps”.


In advance to the official release of “KAIJU STEP”, a new series in “MEBAE”, an educational magazine for kids and babies had started from September. The new series has been loved by both boys and girls and  we have received positive comments from families such as fathers enjoying with their children figuring out the names of the Kaiju, and mothers who aren’t familiar with the ULTRAMAN series enjoying drawing with their children.

And on November 1st (Thu), “KAIJU STEP” launched its first picture book Little Pigg’s Balloon at bookstores all over Japan. Also, a short animation on “TSUTAYA TV”, a streaming service provided by TSUTAYA, has started being distributed.

In addition, celebrating the birth of “KAIJU STEP”, there will be a family event “ULTRA Happy Papa Mama Festa 2018” on November 24th (Sat) and 25th (Sun) at Mitsui Shopping Park LaLaport Tokyo-Bay.


We will continue launching many projects including picture books, animations, goods, and events to provide many children and families this series.
