I would say it looks markedly more Japanese than anything from DaS or DeS because of how ornamental and unpractical it all looks, but that's my opinion. And if they were trying to be like Wizardry how exactly does that say anything about my argument?
They were trying to do something similar 30 years ago.
If you look at the portfolio of Squaresoft games from the 80's to now, they weren't that big on markedly Japanese monsters that's for sure.
If anything the Saga series is more Japanese in its approach than FF.
FF is all about medieval knights fighting griffins and dragons.
Even more so for DQ that only look Japanese because of Akira toriyama, if you played the games you'd see what I mean.
Impractical designs is not Japanese, that's for sure.
Do I need to post all the examples of boob plates from western devs or something?
There's nothing inherently Japanese in the designs of a game like Final Fantasy till we reached the Xth opus.
heck look up FFXII, it's in Ivalice a world that's pretty much Matsuno trying to make a western europe continent.
I could talk about Ogre Battle too...or the old Fire Emblem games before they went full fanservice.
