Koufu-ryu Iai-do's Philosophy 

Our sword technique "Koufu-ryu Iai-do" is based on the philosophy that we protect ourselves safely when someone attacks suddenly.

We are practicing to pursue the concept which means the "helping sword", not the "killing sword".

Ishi-sensei will teach you the method for your purpose or goal, considering your age, gender, physical condition.

If you get interested, don’t hesitate to join the class. Have fun!
