MIJ covered dish - modern?

Today's find. 6" diameter covered dish, no chips or cracks. Is this modern? Made In Japan in black on bottom with stylized chrysanthemum in a circle. (I couldn't find it on Gotheborg site so that's why I think it's modern.)

 

From what I have seen on a couple of sites, the first use of "Made in Japan" was 1921, when the U.S. government required the words to all be in English.

Not sure, but here are a couple of sources. An eBay guide and Kovels:

What do you mean by modern?
I don't think I would put it past the 1970s. Could be as early as the 1940s.
Just my guessing.

 

Wow. I thought it was made last year. It's in perfect condition. Another freebie from the Swap Shop at the dump. I have a theory that someone is dropping off one good piece or one antique at a time. As long as I'm the only collector haunting the place, I get to scoop up the goodies. It's run by volunteers.
