A security firm in a city known as the birthplace of a prominent ninja school is enjoying success by providing guards dressed as the medieval warriors and assassins.

SCC Co., in Koka, first tried to tap the city's growing fame for ninja tourism in 2016, when it introduced security guards dressed as ninja to provide traffic control services for the opening of a coffee franchise.

Its special ninja squad has worked steadily since. The head of the firm, Maya Miyoshi, now hopes to win a contract for the 2020 Olympics and Paralympics in Tokyo.
