I remember a TED-ed animated video that claimed that isolated cultures prospered because they had peace, one of the three examples was Japan. They had an animation of a cute little rabbit practicing the katana. I couldn't believe something so blatantly false could make it past the editors of TED-ed, they even had iconic weapons of Japan's warring states period in the video! I can't find the video now, so I'm hoping it was taken down. But it definitely had TEDx quality information, I have avoided TED-ed for years ever since that video.
