Introduction

Get ready to celebrate International Ninja Day on Dec. 5! This day has been around since the early 2000s and is a great opportunity to honor the brave warriors that have been protecting us for centuries. The ninja originated in Japan during the 15th century, with their signature black attire, weapons, and stealth tactics becoming legendary over time. It's a day to remember all of those who have come before us and how lucky we are to live in an age where ninjas don't exist (in real life)!
