Both feature high-school-age boys helping yokai solve their problems. Both have a fairly light-hearted atmosphere most of the time.
light , pleasant anime about Yokai and an ordinary man who decides to help them return to the underworld
These two anime series have both the same kind of setting where a young man/student can see youkai and has to live with them. Both have a unique atmosphere and are definitely a good watch if you liked either of both!
What they have in common: Yokai, beautiful art, bishounen
I found Natsume Yuujinchou to be a much more relaxed version of Mononokean, but the plot and pacing is still excellent
With different way of seeing youkais besides monsters the main characters, that have the ability to see youkais, are in exciting stories that are full of comedy and touching scenes.
Both shows have an easy going feeling to them. There will be sprinkles of darker tones but nothing that is out of bounds for the respective stories. Both stories deal with humans and their connection to yokai in some sort. There is also a similarity in estranged family members with mysterious pasts behind them which gives us a nice over arcing plot for both. Natsume Yuujinchou is a long time favorite of mine and I really enjoy it's soft visuals while FnM definitely has brighter visuals it's still pretty soft.
More or less episodic shows about beautiful boys interacting with youkai/spirits/mononoke to the sound of refreshing music tinged with a little tradition.
Yuujinshou is more subdued with a more faded colour palette, whereas Mononokean is stronger coloured and louder voiced. Both have a colourful cast of yokai and just enough supernatural action to keep the show moving at a nice relaxed pace.
They are both about people who help youkais, both very calm and heartwarming animes to relax.
Both protagonist can see, and interact with Youkais, both series revolves around helping youkai's in one way or another. (based on first episode)
Both anime are about boys who can see yokai and are casually interacting with them.
Natsume Yuujinchou has a calmer pace compared to Fukigen na Mononokean but both are entertaining to watch.
Both are episodic anime which are about helping youkai with highschool students as main characters.
Both are, cut down to their basics, the Main character(s) helping certain Youkai in a semi-episodic format, meaning that some stories only take one episodes while others take multiple episodes to get resolved. Both also have a similar atmosphere and make (almost) everybody, including the Youkai, seem likable.
In both anime, the MC(s) are also accompanied by an adorable Youkai that decided to stick with them on their own.
Both shows deal with youkai (spirits). Both main characters sees youkai, and others don't see, both anime relaxing. Natsume yuujinchou is more heartful and Fukigen na Mononokean is more comedy.
Both explore the relationships and friendships between yokai and humans, as well as the troubles that come with that connection. The main characters in both are driven to help yokai whenever they can, they even both have a small yokai companion throughout their individual journeys ( although one of them is distinctly more affectionate with their human then the other). Natsume Yuujinchou can contain more of a serious tone at times but I find the message that I took from both was the same in the end. I adored both for the same reasons and if your looking for a feel-good supernatural show that focuses
Both shows feature high school students who not only have the special ability to see yokai, but is able to exorcise them in order to make them move on to the Underworld. Both are true slice of life shows that are very episodic in nature.
They both are about yokai where the main character is able to se them. They also have to hide their ability while dealing with school, day to day life and helping yokai.
Both shows are much the same but still have some interesting differences which makes each show unique and fun to explore, even though you've seen something similar before.
These two shows both show yokai/ayakashi in a positive light, and the protagonists help them rather than hunt or hurt them. Also, they both feature male main characters. While Natsume Yuujinchou is more relaxed and has a slower pace than Fukigen na Mononokean, they're both slice of life shows rather than plot driven. Both shows are really good, and I think that if you like one, you'll definitely like the other!
They both feature two teenage boys, where they "exorcise" youkai.
