5 Things Ghost Of Tsushima Gets Historically Right (And 5 It Doesn't)
2. Fiction: Jin's "Ghost" Arsenal
Sorry, Ninja fans, there's no way Jin could have ever used a smoke bomb in 1274. Or a bomb of any kind, really.
It would be a gross generalisation to say that Japan has had a fairly isolationist history, but Japanese innovation at the time of GOT mainly consisted of who had the biggest bow. Devices like firecrackers and other incendiaries would have been completely foreign concepts to Jin, being introduced almost 200 years later by Portuguese merchants.
While this did lead to "explosive" developments, they were way off from Jin's lifetime. Forget "Jin the friendly ghost," our hero will have to stick with "Sakai the distinctly unfriendly Samurai" for the time being.
Even though Samurai definitely used stealth and nighttime ambushes, their tactics were much more focused on single combat, rather than Jin's "Shinobi" approach.
In one of the more famous stories from Samurai/Mongol battles, Samurai archers started by shooting a single, harmless arrow at the invaders - an outdated practice to announce their incoming attack. This could have done some serious damage to the Mongols, who laughed so hard many of them almost ruptured an organ. They soon recovered though, and replied by shooting actual arrows. Doesn't take a PhD in history to work out who won that fight.
