About Shuriken


stick shuriken

In the Sengoku period, warriors throw stones, javelin, arrow and wakizashi(the short  sword of Samurai) in the battle.It is said that these arts became the basis of  skills of shuriken.

Shuriken is not necessarily a weapon of ninja. It had been established as one of the martial arts.

There are two types of Shuriken.One is stick shuriken (Bou shuriken) such as dagger and nail, the other is cross-shaped or star-shaped Kuruma shuriken.

There are two ways to shoot shriken.The way to shoot it straight and the way to shoot it spinning.

Without long-term training, it is hard to hit the enemy by both shuriken.

Because the shape of stick shuriken is simple than Kuruma shuriken,it is easier to make and the making cost is lower.

When attacking by Kuruma shuriken,Ninja must shoot it spinning.There are various forms than stick shuriken.

Because there are many blades in Kuruma shuriken, the killing power is higher than stick shuriken.However,Kuruma shuriken is difficult to carry and making cost is higher.

Flying distance of shuriken is about 15m and it is difficult to inflict a mortal wound by shuriken.

Thus Shuriken is not a main weapon, it was being used for self-defense and the assassination.

It was effective for assassination if I a shuriken is coated in the poison such as aconites.

To bring back the accurate information is the most important thing for the Ninja's mission.

For this reason shuriken is one of the best weapons for Ninja because it can wither with enemies easily.

The basic principle of Ninjutsu



I often feel that foreign people have a misunderstanding about the Ninja.

I try to tell the real information of the Ninja through this blog.

Ninja must be first of all right-minded. Ninja's missions were like those of thieves.

So what is most important is heart of justice.

Without a heart of justice, they becomes just like thieves.

To stray from the path of righteousness means they were abandoned by God or Budda.Ninja had gained superhuman strength by faith of God or Budda.


Special skills of a Ninja is called "Ninjutsu".

There are two types of Ninjutsu.




Yin Ninjyutsu


Yin Ninjutsu is the way to achieve the mission by hiding under cover of darkness.

The missions of Ninja most people imagine are kind of Yin Ninjyutsu.

Yin means darkside and shadow.

Yin Ninjutsu is the art for sneaking  into enemy's territory to sabotage or to explore the inner workings.

Jyoueinin How to surprise or intrusion to the castle

Kanin The way to break into the house

Kaiko The method for opening the door

Shinobiyouchi The way of disturbance tactics


Yan Ninjyutsu


Yan Ninjyutsu is the way to carry out the mission by stratagem without hiding the figure.

Yan means light.

Ninja disguised themselves as a monk or priest and then penetrate into enemy's territory.
