I like this one quite a bit, though I listen irregularly. My favorite part is that you're getting all kinds of interesting btc stuff, but quite indirectly in many cases, and learning a lot of stuff about Japan, too.
It's an illustration of a general idea, I think: if you have smart people engaging with something consequential, what you really have is really about The World at large, regardless of whether it's ostensibly about professional wrestling, or horticulture, or the history of the automobile.
