My Video Went Viral: Ordinary Salaryman who Does Umbrella Martial Arts

By Danielle Erves on June 29, 2017

Have you ever heard of Kasamurai? Neither had Jukin Media until we came across an IT engineer practicing the art. By definition, Kasamurai is a martial arts performance using umbrellas, but for Hiroaki Tanaka, it is his passion. He started practicing martial arts at a young age. He had fallen in love with the art after playing Dynasty Warriors, a beloved video game, as a child. Tanaka also drew inspiration from the 2000 action film “Crouching Tiger, Hidden Dragon.”

After I passed the age of 30 I became less agile [my body didn’t move as well] so I wanted to capture my performance before I become totally unable to move.


Once deciding to record himself, Tanaka uploaded his videos to YouTube and has over 50 videos showcasing his martial arts skills using multiple objects, but Tanaka’s primary weapon of choice is an umbrella.

I mainly practice using my hands and don’t really use weapons.  But I thought it looked like fun so I tried it out (using umbrellas).

Tanaka started this martial arts training when he was a child, he took Shaolin Temple Kenpo for 14 years, beginning in elementary school and continuing all the way through university. Tanaka added Krav Maga and Systema (Russian) Military Martial Arts to his training.

After practicing for many years, he started to develop his current routines on his own. He practiced for only a month before he started filming himself. Tanaka never thought his videos would be all over the internet, but noticed his fan base growing when he began to show his love for martial art films in his own videos.

I never thought that my videos would be seen by this many people so I was pretty surprised.  I wondered why it got so popular.  So honestly, yes, I was very surprised.


Tanaka says his family was surprised by people’s interest in his videos too. By day, Tanaka works in business sales as an IT engineer, as well as teaching IT engineering. He says he is an “ordinary office worker.”

When it first went viral it became pretty popular on social networking sites but it’s not like I became famous in real life or anything.  Like, no one recognizes me on the train or anything like that.

Despite Tanaka’s feelings of not being famous, his videos continue to do well on YouTube and Facebook. Hiroaki Tanaka plans to continue to make videos practicing Kasamurai. He continues to make videos using different instruments. Check out Tanaka using everything from a hanger to a construction cone.
