What are the differences of those two ninjutsu styles? Aren’t they all just ninjas? In this article, we will introduce you the history and basics of ninjas and ninjutsu and the differences between the Iga-ryu and Koka-ryu styles.

What are ninjas?

Ninjas (忍者) played a spy-like role in Japan from around the Kamakura period (1185 - 1333) to the Edo period (1603 – 1867). They carried out secret mission of espionage, infiltration and sometimes even assassination.

They used special ways and tactics, collectively called ninjutsu (忍術), to carry out their secret missions. Ninjas were said to have played a crucial roles in many fights and battles.

When did ninjas exist?

Ninjas were mostly active in the underground society. Prince Shotoku (574 – 622), is said to be one of the first people to use ninjas. It is said that Prince Shotoku used ninjas to keep an eye on the imperial court.

Ninjas were referred to as “shinobi (志能便)”. Otomo-no-Hosohito, Prince Shotoku’s ninja, is said to be the first “shinobi” in Japan.

The term “ninja” only became familiarized during the Taisho period (1912 - 1926). Until then, the word to describe ninjas varied throughout the different regions in Japan.

During the Asuka period (552 - 645), the term “shinobi” was commonly used. Entering the Warring period (1467 - 1590), it was “kanja 間者”, and in the Edo period (1603 – 1867), they were called “onmitsu 隠密”.

In regions like Kyoto and Nara, ninjas were called “suppa 水破”, and in Fukui they were called “shinobi隠忍術”, but the word used different characters.

Do ninjas still exist?

This is the question that we’ve all been wanting to ask. Do ninjas still exist? Or have they gone extinct?

Entering the Meiji period (1868 - 1912), police units and military forces were established in Japan. This forced ninjas out of business, and today, it is said that there are very few real ninjas remaining.

However, the whole point of a ninja is go unnoticed at all times. Considering that, they might still be roaming the streets of Japan.
