Those are always welcome, thank you. I know of (1), (5) and (6) but haven't started them yet.

I've dabbled a bit in the "History of Japan" podcast but since I encountered some episodes that weren't accurate (although they weren't strictly about history), I've lost trust and stopped listening. Apart from that, the "Romance of the Three Kingdoms" podcast is ok, albeit a bit too comedic at times for my taste.
