>>9441064they banned christianity because they heard about iberian conquests elsewhere in asia shortly after missionaries arrived and thought it was a subversive idea designed to create spies and enemies from within, so that fear of conquest was probably justified, but at the same time if europe wanted to take them over it probably would've been easy since they had just gotten over killing themselves for 150 years
they certainly do not know how to make weapons of war efficiently, given they got the original chinese cannons at the same time europe did (those things on sticks they were using in the movie) but made no advancements on them while europe was making them more efficient, as well as making the crossbow and longbow
they developed quickly after meiji but it's hard to catch up on the rapid industrialization we had, i saw a video demonstrating our throughput of naval production compared to the japanese in the years prior and during the war and it was easy to see they were out of their league, even if we had two oceans to fight in
