For some people, Ninja Day comes only once a year. But I say: live every day like it’s Ninja Day.
Brian Ashcraft of Kotaku explains that February 22 is Ninja Day because of a pun in the Japanese language. The cities of Iga and Koka are historically associated with ninjas, so people there are celebrating enthusiastically. Government workers are dressing as ninjas and interacting with residents appropriately.
On this most cherished of holidays, wish the ninjas in your life, such as the one on the ceiling directly above you, a merry Ninja Day!
