Small celadon dish

I found this at the car boot yesterday. This stall just had boxes and boxes of stuff for £2 or less. This was 50p.
I think it's a Japanese celadon dish, mid century, but maybe we'll off the mark as I dont have much experience in this. Ø = 11cm.

 

Plug in the keywords Seto Celadon porcelain. A lot of it will turn up in image search.
Whoever made it signed it on the front of the plate by hand. I don't think you see that very often.

 

It may not be a signature, it could be the name of the flower or a description of the mood of the scene, or even a line from a poem.

 

OMG, that's right, I know that too, but it didn't cross my mind at the time I posted. It's a good thing there's always more than one brain on duty around here, lol.
