Hi tartiflex,

something went wrong with the wikimedia_commons tag, you linked many (around 10) categories that do not exist on Commons.

In this changed you tagged wikimedia_commons=吉野郡, yet such category doesn't exist: https://commons.wikimedia.org/wiki/Category%3A%E5%90%89%E9%87%8E%E9%83%A1

In another changeset you added =Category:Iwate Prefecture, but that category as well doesn't exist on commons: https://commons.wikimedia.org/wiki/Category:Iwate_Prefecture

Generally, if a wikidata=* tag is present, there's no need to add wikimedia_commons since it can be retrieved from it. 

Could you check this values and fix them where needed? A tool to find them could be this one: https://maproulette.org/browse/challenges/40762
