You’re holding up a bad inference piece on data of questionable value that is touted by the Japanese fishing industry saying Japanese fish is fine to eat. And there are even contradicting studies.
Did you read this piece? if you cant see why this is not people who know what there talking about and instead an entire industry, commerce and job sector and country that have a financial incentive to produce a specific answer…
I dunno how to help.
Someone on this thread was even nice enough to have leaked other info for ya…
