Do any vendors sell Japanese import figures like mafex of figuarts?

They sure do! Ageless geeks always has the new Figuarts, Mafex, Storm Collectibles, Revoltech, Figma, and just...everything.

I would say yes.

I know there's a bunch of vendors that sell Japanese items but I'm not sure specifically those. You might possibly get lucky and find one

Yes, I have seen a vendor selling similar figures. I don't know the exact space though

There's around 3 or 4 vendors that sell items from japan, figures, gundams, plushes, etc. Its worth the try and look.

I've seen figures, but mostly comic book characters.

I believe there are a couple of venders
