re History of Japan video: Why did you state that Kukai brought Zen Buddhism to Japan when he actually brought Shingon Buddhism; a closely related sect, but not the same thing? (reference: "The World of the Shining Prince, Ivan Morris, page 100)
that was a mistake. mistakes can happen when you try to learn the entire history of a country extremely fast. i corrected it in the youtube version with a youtube annotation. so far this mistake has resulted in very few deaths, knock on wood
