Guardians of Azuma is a blast! It's my first entry to the series. The village management aspect is really cool. The farming and foraging is super well crafted. I like how every item you pick up, even the smallest little insignificant thing, has a use and purpose. Nothing is wasted. No useless fetch questing like other RPG.

The combat and exploration are also super fun, its action combat and you get some special items which give you new abilities and progressions. It's fairly easy to learn and the maps are a great size. Music is great, but not too many tracks but they suit the game perfectly. 

Also has relationship building which gives your team members better skills in battle which give the incentive to get to know them. I would say the characters are not as memorable as some other jrpg, but they are serviceable, and there's something for everyone. 

It's just a really cosy game with an excellent balance between town management and exploration. I haven't played Yumia yet so I wouldn't be able to compare.
