I found the surrender broadcast article fascinating. I also hadn't realised that the line about "enduring the unendurable" was borrowed from the Meiji emperor's statement at the time of the Triple Intervention, used to stand in for a direct reference to defeat or surrender. (Nor the fact that Denon made the recording equipment, but that's less important.)

No, me either! To be honest I hadn't read the entire text of the speech in Japanese before -- last time I tried, a few years ago, my skills just weren't up to it.

(And I was very surprised to find the Denon page so high in the search results, too.)
