Bushido (samurai rpg)

while this rpg was not “made in Japan” … it is very definitely about a part of the culture of “Old Japan” … and I will not even try to count how many anime and manga that use samurai characters or are “samurai era” stories … there are LOTS of them

this is what I have been able to find of the game
