Origins of #Iga-#ryu Ninjutsu and the history of Iga
From when did Ninja, who worked in the world of shadows, exist? Those roots are found in the “art of warfare” that began around 4000 B.C. in Indian culture, was passed to the #Chinese mainland, and around the 6th century, passed through the Korean peninsula and crossed over to Japan.
In that period, a man name #Otomono #Sahito, who was used by ruler Shotoku Taishi, is said to be the root of the #Ninja.
Have you ever heard something like this? "Shotoku Taishi could hear the words of ten people at once." Actually, there is also a theory that he used ninja to obtain intelligence beforehand. However, it is still amazing that #Shotoku #Taishi could remember all that intelligence...
The continental #military #strategy that was brought from #China was developed in conjunction with shugendo, a practice involving mountain training, and adapted to Japan’s extremely hilly, narrow geography, becoming unique #Japanese #strategy. From this body of strategy emerged Ninjutsu. There were shugen studios in the Iga and Koka regions. Also, the houses of Todaiji and Kofukuji in the Iga region had most of the country’s #warriors, and the lords of these houses adopted guerilla-like tactics, and kept the peace by containing one another. From this, #Ninjutsu was developed.
