So I got all the info I needed but I found out I didn't need to submit so this is based on internet research and Japan Embassy:
Needed only if you lived for more than 6 months in the last 20 years
Instead of uploading pcc, upload in writing asking for a letter to be given to the embassy for such request and that you will open the sealed envelope when returned to upload
Book an appointment with the embassy and take the letter with you ( without the letter they wont provide a pcc).
PCC should be done in 1 to 3 months
Embassy to notify you when its complete for you to pick up
Collect the envelope and open the sealed one in order to scan and upload
There should be a space for you to upload letter on
