If you like Japan the “history of Japan podcast” by Isaac Meyer is great. More than 400 episodes on every topic from religion to culture to war. The first 40 or so are a chronological history of Japan. Then there are great series that deep dives on topics like the Meiji revolution, the bombs, Hirohito, the Sengoku Jidai, democracy in Japan, so on.

It goes from antiquity to the extremely current (like a four episode biography of former prime minister Abe Shinzo)
