OMUSTA Contest

Ninja used to work on agriculture when they were not under the operations.


Iga city in Mie prefecture in Japan, which has declared NINJA CITY to all over the world, is famous for rice as it has the brand called Iga rice.


Therefore, we came up with the unique event where the participants eat rice ball, which Ninja may also have eaten when they were on the mission, with smiling along with the various themes in order to compete over how they can eat it deliciously rice ball against Ninja city’s farmland with the thought of Ninja who actually lived here in the old days and notice the importance of agriculture inherited from them.


The idea basically comes from the word, OMUSUBI, meaning rice ball in Japanese, since the word “MUSUBI(結び)” implies “EN(縁)” meaning “fate” in Japanese, so there should be good fate between all participants and Ninja city.


There will be a great opportunity that a lot of people from all over the world know our Ninja city and create the chance for them to visit us by uploading the picture of the competition.


We, shichiten battou, is trying to make this culture here, Ninja city.

OMUSUBI, connecting Ninja city and the participants.

Rice planting in spring and rice harvesting in autumn.

Catch the moment of when the participants fill their mouth with rice ball deliciously with Ninja costume, against the farmland showing how Ninja was living old time.
