ah...oge,well I think it's same thing in here and also we can't understand a little bit about 1940s Japanese.
Well I can understand 60~70% of 1940s Japanese but it's a little bit complex word than modern Japanese.
I thought like that when I heard your opinion.
But I guess WW2 USA military did get the important info from that old Japanese, I guess that thing is unbelievable. https://social.076.moe/url/445613
