I don't have much in the way of knowledge about Japanese history, but if the comments on Reddit are anything to go by (usually a hyper-critical bunch) it seems that most of the major details are broadly correct. (Turning on annotations fixes a couple of on-screen errors.) I'd love to see more history videos from Bill Wurtz (perhaps a series in the style of CPG Grey), but alas this is the only one and it seems likely to stay that way. Do check out his bizarre collection of four-bar jingles, though.
That's all from the blog this week. Monday's a holiday here in the US, so we'll be back on Tuesday with more news from the world of R. See you then!
