Super Self-defense KOROHO



Super Self-defense KOROHO is simple and easy to learn .

Super self-defense KOROHO has been well publicized in televisions, newspapers, andmagazines.

We have held many seminars in Japan and foreign countries. KOROHO has been studied and used by the French National Special Police (Gendarmerie) in south France and Krav Mage (Self-defense ) instructors in Italy.There is also a KOROHO Federation in Europe .

KOROHO is practical ,simple and easy to learn , so students include not only policemen , military men , bodyguards and martial artists, but also the general public .

In today's life, most of criminals use some type of weapon(knife, gun, stick, etc).

Most of today's martial arts set the sport as the main goal.

Even if you practice martial arts for many years, it is very difficult to protect yourself from an assailant's sudden attack with a weapon.

The KOROHO system is easy and quickly learn . KOROHO employs mainly high speed and simple movements to guard against a sudden attack by using basic human instincts and reflexes.

So, even if you do not have strength or a big body, you can defend yourself from an assailant.
