I have just received Tanegashima and the book looks good so far. My friend from Samurai-Archives, Kitsuno had a big discussion on Nobunaga and the 500 rifles he ordered in 1549 at the Kunitomo gun factory. What I read from the book so far and only a glimpse. Nobunaga had help from Hashimoto Ippa to buy the 500 guns. I will discuss this topic in great length later.
Tenka no Tame!
