This book is about kiku-jutsu. “ki” means “measuring” and “ku” means “90 degrees”,and”jutsu”means “Art, Way”.

It has been said that the technique is the most difficult in construction, and can only be handed down from father to only son.

This was a very mysterious world.

However, if you understand the world of mathematics, you can understand the kiku-jutsu.

kiku-jutsu is very mathematical and not something you can understand with your senses or experience.

It is an academic skill, and if you know it, you will be able to grasp the virtual space, so you can efficiently build any building.

It’s one of the best skills a carpenter should wear.
