On the human village side of things, I actually disagree with the feudal japan aspect that often get brought up :
This might seem like zooming too much on the "feudal" aspect of things, but people's place and role in a feudal society was pretty much dictated by their class, yet the human village doesn't have the all of the various social classes that consitute said social system : there's no leader figure (if we go by Forbidden Scrollery) in the political sense, and no evidence of the presence of a ruling class to be at the top of the social ladder ; furthermore there's also no samurai nor warrior class, as not only there's no ruling class for them to serve, but also because anything that would require martial prowess is actually handled by literal superhumans and heroes.
This means there isn't a proper governing body either in the human village, and quite possibly none of the bureaucracy that comes with it's organisation : so, unlike poor Peasantosuke who's tirelessly working the field to pay taxes and feed the family before getting conscripted for a war against Warlordjirou, or the questionable Vagrantarou who is trying to make a breakthrough in order to climb the social ladder and directly serve under the ruling class, the average human villager should have more freedom and less authority breathing down their neck compared to their real life counterparts. I'd expect the human villagers to just do their daily tasks (there are some farmlands in some places so there is probably farming going on) then hit the pub or something.
Furthermore, human villagers can enjoy the medicine of Eientei, occasionally patron a Zashiki Warashi for taking care of the house, may or may not enjoy the conveniences of kappa wares, and those lucky enough may occasionally enjoy the novelty from foreign imports. There doesn't seem to be banditry to worry about, and there are reliable people with superpowers that are always ready to handle business whenever needed. So, aside from occasionally shaking in their straw sandals whenever there are any suspicious supernatural activity that boggles the mind (or could be blamed on youkai), or besides needing to get behind the human village's gates before dark, there doesn't seem to be a lot of worries in the daily life of the human villager.
As for whom to seek guidance from, human villagers actually have it pretty easy since the people and "institutions" they should trust are pretty clear in what they do : there is the temple school for the education of the children, there is the storied household of Hieda for matters pertaining to serious counsel and extra education , and most important of all, the religious leaders, who obviously hold a lot of authority on moral matters since gods and deities literally exist and occasionally pass by : not only can the average human villager experience very practical benefits or witness very real consequences when doing as the religious leader say, but can also experience a new and different lifestyle depending on the religion or the ascetic practice that they choose to diligently follow (going by Miko's aspirant disciples and Byakuren's human followers). Human village people are VERY superstitious and revere the divine, considering how impactful and real it is, so practices and tradition that have anything to do with whatever superstitions are also going to have an important place in the human villager's psyche and daily life.
Anyway, when it comes to mundane life, there is actually a lot of activity and excitement for the humans : you have the gossips from either the dumb newspaper or socializing places that may or may not have some raccoon activity ; you have the festivities and celebrations that are held quite often by the Shrines and the temple, which tend to have stalls that are manned by those nefarious Youkai and fairies, so obviously exciting ; you have the various bars and food vendors, or even whatever fun place there may be in the village (such as Madame Komakusa's gambling den) ; and also simply the possibility of exploring Gensokyo for those who dare. All in all, plenty of good time to be had, while people that wander from outside may be bored by the lack of more modern entertainment (no internet, no TV, actually experiencing the boonies, yikes).
All in all, rather than being feudal japan like, I think it's more correct to say that life in the human village is more similar to that of a very big rural community that's quite behind only in technological aspects, heavy in traditionnal and religious undertones, with the occasional out of place tool or way of thinking. So it's somewhat like the amish except more japanese, more cuteness, more faith, and more magic.
"Feudal japan" aspects can only be purely on the aesthetic side of things, with little bearing on how their society should work.
