Is there a way that Pioneer Japan, Kuraray, Mitsubishi and WEA can be added to the Reverse Mint Marks database?
As explained above this is only useful
where the master reference is not the catalog number.
For the manufacturing sites you mention, they are using the catalog reference, not a serial number.
You can simply use the Advanced Search and filter titles per "Pressing Factory".
