February 22 is "National Ninja Day." The Japanese holiday isn't an official day off. That is, at least not for those unable to slip out of work.

Why 2/22? It's a word play, because in Japanese the number two is "ni." You know, kind of like the "ni" in "ninja" (忍者), but with "nin" or 忍 referring to endurance, patience or restraint.

Or better yet, it's reminiscent of anime character Ninja Hattori Kun's "nin nin" (ニンニン) catchphrase.

The cities of Iga and Koka have been spearheading the holiday—and for good reason. Iga in Mie Prefecture is historically a ninja stronghold as is Koka in Shiga Prefecture. Obviously, this is a push to promote the region, and Japan has lots of these kind of days. This one, however, is the best.

In Koka's city hall, the local bureaucrats have dressed up in full ninja garb as they answer phones, work on the computer, make origami throwing stars, and meet with citizens—shinobi style.

Since February 2, ninja events have been going on across Japan to publicize the day. The holiday is new and still not widely known, even in Japan. But national press coverage is changing that.
