Bows and Arrows of Japan

A Japanese bow is very long.
The regular size is seven feet long which is the longest bow in the world, I think.
So the arrows are long too. Since the guns introduced to Japan in 1543 bow and arrows were still important weapons as well as sporting goods.
To concentrate the minds, shooting bows had their existance as a marshal arts. Also in Japan bows and arrows have some spiritual backgrounds.
Bows and arrows are believed to avoid evils.
When practicing or competing, a set of four arrows is regular way of shooting.
The distance to the target is about 30 yards.
There are many fans of Japanese bow shooting. When you see an acutely weapons bow, it is suprisingly fat and heavy. Why is a Japanese bow is so long?
I think it is because of the materialsa. They use the combination of bamboo and wood.
They used be varieties of arrow heads. Some were square and some are thin.
As a matarshal art is is a good choice, because it is sophisticated. Manner is important.
