I would check to be sure no change has occurred with the stereotypes. My office-mates in Japan were shocked when I, at age 40 or 45 finally got my b-type checked and was told I am an “A+.” They assumed I was creative, arguementative (i do not think i am, but i am not sunao), pretty much went my way (really, I am more eager to work for the good of society than the company, which was their test for socialization), had a poison tongue exercised in my essays and translation-checks, etc. . I believe if I recall right, that I was supposed to be a type of B (or maybe O i cannot recall) like the guy from Kobe who was always doing manzai like arguments with others (to tell the truth, i felt sheepish next to him).

From what you write about A, they probably would not have been surprised at my A. 敬愚

You are right,I was upset and over emotioal,(and perhaps jingoistic)I take it back what I said in the previous posts.
I fully apologize.

The influence of past wars on present day societies is one of the most fascinating areas of the study of history, and as such, it is a perfectly acceptable, if not even desirable, matter for discussion on a history blog. To wit, Japan is not the only modern society whose rhythms, expressions and institutions have been indelibly marked by early 20th century mobilization, but topics on this site — for obvious reasons — will tend to focus on matters Japanese.

As far as I can see, Eisuke, you are the only person here saying anything about “innocent bloodtype games” in the context of any kind of REVIVAL. The discussion has been about past origins — not future directions. Past…Future…Pretty critical distinction there, and one it would have behooved you to make before joining this thread.

The blood type=temperament topic, I think, is one of deep historical interest, because it is an example of something which everyone in Japan or at least anyone who has spent any time in Japan will have experienced or knows something of, but which has a fascinating historical origin.
