This is the first movie in the Yokai Monsters Trilogy, currently all 3 movies are now on Shudder Canada as of August 22nd 2022 (I do not know about other regions)
This is a fun movie, the movie functions similarly to Kaiju movies like Godzilla & Gamera but it's a bit different than those movies as well.
The human story is kinda dominant & generic but the monsters are still very entertaining when they come in.
The effects are primitive by today's standards but it's the 60s & they might not have had the highest budget but personally I'm okay with that but I'd say lower your expectations just in case,so you don't walk away disappointed.
It takes place in Fuedal Japan which is a good setting for the movie & brings a strong cultural feel to the film.
The yokai are really fun & also at times genuinely creepy,this movie has some great atmosphere at some points.
If I'm not mistaken,this movie actually unsettled me enough to have some weird nightmares the night I watched it.
Overall,lower expectations & have fun with it. It has subtitles so forewarning but it's a pretty fair 80 minutes.
