It's fun to watch, but you should always take it with a grain of salt. I imagine the "budget" to produce English-language NHK content must be coming from the state's tourism board or something, so in the five years I watched the channel, there was nary a negative fact about Japan ever mentioned. There are no problems, no conflicts...only beautiful country where old women still gather acorns by hand, and 80 year-old men who are free to hone their lifelong craft of making tofu.
