where i live there is no places that teach any type of sword fighting like kendo, and since i am a kid and cannot travel to the nearest city which is like 45 mins away and I think may have a kendo dojo I cant get to it, so.. I was wondering if there is any websites i could visit that teach it online that someone may know of.

I was also wondering what iaido ( hope i spelled it right ) is because i've heard of kendo but never iaido.

and i was also wondering what type of martial arts the samurai studied or if it was more then one.
