Chinese or Japanese Plate?

[Maritess Nacua]

Hello there experts.  I wonder if this is Chinese or Japanese, and what dynasty?  Thank you.

This is Japanese. When you have blue rings near the foot rim like this one, it is usually not Chinese.

Thanks Peter!  Wow I have a Japanese collection now.  Any idea of the age.  I am thinking World war II maybe?  What do you think?
