Hmmm, what stands out for me is the shikoro, which is actually the layered plating on the back and sides of a samurai helmet. So that one is probably a media-made blade. I don't recall what they were called, but I do remember tall shields of laminated wood; I wouldn't be surprised if they had leather on them. Jirai/jiraika are mines, but I don't know how far back they go. All I know about gobo is that it's a salad. Poison gas bombs.... I feel like it's so media-laden that it might have, but I don't know for sure...
Actually, the chinese could already use landmines and the like by the 16th century. The Japanese typically scoffed at the use of explosives except as siege weapons up until Nobunaga handed Katsuyori Takeda's ass back to him on a silver platter with a musketeer army 1/5th the size of his own.
