What is the real Japanese fencing fighting like?

It is an annual traditional sport in Japan, that is, a fencing competition simulating ancient wars, but all of them are real people. Unlike sports such as kendo, fencing fights wear more rigorous armor and have several weapons. However, fighting is not good-looking, at least not as good-looking as in movies ... a bit like ... monkey jumping ... more like wrestling immediately after close contact, and stabbing with a short knife after falling (of course, it won't hurt the opponent).
