The US Public Broadcasting Service (PBS) has a YouTube account. A while ago, I found a series of programs from 2009 that they produced about Japan's Edo period. If you're interested in Japan, I think these videos are a good general introduction to that time in Japan's history, a period covering over 200 years, when the Tokugawa shoguns ruled and Japan closed its doors shut to the rest of the world. I thoroughly enjoyed watching this series and gained interesting insights into this period in Japan's history.
If you're Japanese and trying to learn English, I also think that this is a good series to watch to practice your English listening comprehension ability. It's also a chance to see and analyze, and perhaps critique how Japan is portrayed in this particular production from a generally well-regarded US media network.
The series is titled, "Japan: Memoirs of a Secret Empire," and is mostly based on written accounts of European eyewitnesses in Japan during that period—Christian missionaries during the early part of the period, and then other Western foreigners who were able to stay in Japan during its self-imposed isolation.
