"Never lasted"?Exocet said:Indeed,the katana wasn't used by the common man on the battlefield,but that doesn't change the fact Japanese warfare didn't evolve for centuries,it almost did with some great generals trying to integrate arquebuses,but it never lasted.Besides,you cannot in any way say that Japanese tactics evolved as much as European tactics.
The arquebuses were introduced to japan in 1543 by the Portuguese, and since then they were widely used by japanese armies.
Could you perhaps have read a bit too much of the romantic misconception that the samurai managed to ban the use of and further construction of muskets during the Sakoku?
Im sorry but your displayed views of the history of japanese warfare reeks of romanticized misconceptions and stereotyping. The country has an extensive history of bloody civil wars, overshadowing the history of warfare of a lot of other countries. You can't seriously mean to tell us that it wasn't in the interest of the japanese generals and daimyo's to develop and evolve their tactics and strategy considering their warlike ways?
