Essential Japanese: An Introduction to the Standard Colloquial Language

1950s self study textbook

Another textbook from my "how they used to have to learn Japanese" collection, this was first published in 1954. As was normal for a textbook of that time, it is entirely in romaji. It spends a fair amount of lesson one trying to teach you pronunciation. Interestingly, the author wrote this with the self studying individual student in mind, though he does recommend that you "hire a native tutor", ideally "one who hesitates to speak English" and a "talkative person who is not too highly educated"
