Goshiki mai – Five Colored Rice of the Ninja

Secret Messages were conveyed with the use of elaborate codes that would be overlooked by anyone but the recipient. The ninja’s ploy included rice grains dyed different colors (goshiki-mai) as well as knotted rope (yuinawa-moji) as well as letters that only their allies could understand.

In understanding the “Goshiki-mai” (Five-color rice) Rice grains were dyed blue, yellow, red, black or purple and arranged in different combinations or patterns. With this technique, the ninja could make over 100 different codes.

There is a new Historical Ninjutsu video being released this week on this topic from myself and Antony Cummins that you can all see and understand these old methods of secretly passing information.


The lesson today comes from my own personal collection and study of these documents. I hope that this helps with all of your training! Take Care, Be Safe and Good luck in your Journey of Budo!
