My first Imari plate, please help!

Good evening,
I wonder if anyone can tell me anything about this Imari plate below. It’s my first purchase and had googled it, but then I m’ve got more confused! I could not find anything about the mark at the back, most of the similar plates do not have any markings… does the marking on this plate say anything about its age and style?
Thank you.
Kind regards,
Simona

 

Different design, same mark:

Being sold as decorative plate for 12 EUR

Mark is: 謹製 栄和 according to Google: Made by Eiwa
If you google for 謹製栄和 or Eiwa Kinsei, you'll get more similar plates

 

According to Gotheborg, "Eiwa Kinsei appears to be mostly an export ware dating from the 1950s and later." He suggests the red mark such as on your plate may be 1970s.

Kind regards,
