I’ve been watching the 50th anniversary remake of the classic anime Dororo, which is supposed to take place roughly in the 1600s. The way it portrays the time period seems very difficult. A lot of violence and hunger; at one point they show a home full of war orphans, many of whom are missing limbs, and at another point they show farmers desperate because their rice crops are failing. Even the title character is an orphaned peasant child whose father was killed by violent samurai and mother starved to death. Was this the reality of life during that period? I was able to find out that the warring states name comes from local lords competing for power with a weak central government, but how much was your average peasant aware of/impacted by this?
A home of war orphans lots of whom are missing limbs seem to be more of a scene from the aftermath of WWII (which makes sense consider that manga was written in the late 1960s) rather than the Sengoku. But the reason is not that civilians weren't targeted and there weren't orphans, but that it's highly unlikely that poor farmers, especially children who presumably lost parents/guardians at the same time, who had limbs violently cut off would have had access to the required medical resources to survive and would have died then and there. There also weren't institutionalised orphanages, and children with nowhere to go would likely have been taken in by Buddhist temples.
Everything else listed would have been fairly commonplace for the Sengoku. Actually it's probably a bit worse as marauding armies had a habit of burning down villages, there would have been been bandit gangs roaming the countryside, selling war captives into slavery was commonplace, and then there's the occasional massacre.
