There is no pic so I can not see your plate !! But if it says Imari then that’s what it is !! Imari is not a brand or a particular type of pottery !! Imari is an area of Japan !! So much pottery from that area was exported to other countries through the port of Imari that the items came to be known as Imari !! Much of it was unmarked other than what you have on yours or a stick on label !! There are many different designs of Imari made pottery/porcelain !! Look on ebay and you will see many of them !!
