In 1941 Japan was just as dependent on outside sources for its oil supply as it is today. Domestic production of synthetic fuel amounted to only three million barrels annually; the rest of Japan’s needs—over 90 percent—were made up by imports.

...

Eighty five percent of imports came from one monolithic supplier—Japan’s own private OPEC—the United States of America. And by 1941 relations with the United States had deteriorated to the verge of war.

...

In May, 1939. Ambassador Joseph C. Grew in Tokyo had warned the president that “…if we cut off Japanese supplies of oil…and she cannot obtain sufficient oil from other commercial sources to ensure her national security, she will probably send her fleet down to take the Dutch East Indies.”

...

On July 26th [1941] President Roosevelt ordered the freezing of all Japanese funds and other assets in the United States and the placing of all petroleum exports to Japan under embargo subject to license. Britain and the Dutch East Indies quickly followed suit. It was originally intended to use the licensing authority as a lever for further bargaining or to avert a crisis. But it soon became apparent that in the current political climate no licenses could be issued and none ever were. The oil cut-off was now complete and Japan was thrown back on her stockpile.

The Japanese air raid on Pearl Harbor of December 7, 1941—the “date that will live in infamy”— lives in history as the military catastrophe that plunged America into World War II. But for the Japanese naval staff, the attack was essentially a sideshow introduced out of excessive deference to the “worst case scenario.” Admiral Yamamoto, the Japanese naval commander, had convinced himself, in the teeth of all the evidence of American naval inferiority in the Pacific, that only if the U.S. battle fleet was dealt a knockout blow would his convoys be secure from interception and time afforded to build a defensive ring around the new conquests.

paragraph 3 of this long as fuck wikipedia page mentions competing embargos between [japan and china] and [united states and japan]. It's a small detail on that page but in our discussions in the history department in college [i bounced between a lot of majors] it seemed much larger.

I mean, my point in saying its a literal physical form of etiquette that is systemitized is to ... differentiate it from many other cultures, where its mostly just linguistic.

Not too many other cultures have a whole system of physical manuevers that also comprise part of how respect is culturally conveyed.

Microexpressions? Nah, this is a macroexpression.

Tons of broader Japanese culture also has systemitized, physical rituals... essentially, complex dances, that either accompany or just literally are an actual ancient tradition.

There is an extreme amount of emphasis on physical control of your own body, compared to other cultures I have interacted with, have studied.

Of course, not everyone takes all of that so seriously, is so formal... culture changes over time and is never totally homogenous... Japan is also rather famous for its extremely expressive and distinctive fashion/lifestyle sub cultures.

There is differentiation, but its... its sort of like the Overton window for etiquette is in a significantly different position as for many other cultures, if that makes sense.
