It's possible you might be thinking of the Japanese Quail (Coturnix japonica), which is a very common breed of quail often kept for eggs and meat.
It's also possible there's a specific line or strain of Japanese Quail that is bred in the Seattle area, but this would likely be a local name or designation and not a recognized breed name.
If you could provide more information about where you heard the term "Japanese Seattle," I might be able to help you further!
