The concept of dojo training is quite new in history, training indoors on wooden floor or mats. Historically all training was done outside in nature, both daytime and evening, and in all weathers. This is of course where battles were fought
There is of course a lot of ninja training done at night in the dark
All the ryuha we take our training from originated in nature
Anyone who had trained abroad in Japan, Thailand, Philipines, China, even America and Brazil will tell you a large proportion of the training is done outside
