Anyone recognize this signature?

Hello friends....I am working through my collection and wanted to see if anyone can decipher the signature on this ceramic pottery tray. Assuming it's oriental, the bamboo like edge on it crisp lines ... any help would be appreciated!

I will be posting images in the post below...Thanks in advance!!!

 

Flipping your picture to make it easier to see the mark...

 

I don't know what it says, but I am pretty sure tie.dye's left side picture is correct and Japanese.

 

Agreed. After I posted the one on the right side, I thought that didn't look correct, so I added the other one. Even when I can't identify the mark, I can usually tell what way the mark should be oriented.

Edit: Did a little searching around but didn't find the mark. I think I've seen this mark before, but after not being able to identify the Andrea Sadek mark on a previous thread, I'm beginning to think some of these blue squiggly marks are starting to look the same to me.
