Hello, I'm PrussianOwl. I wanted to let you know that one or more of your recent contributions to Mining in Japan have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. PrussianOwl (talk) 21:03, 19 November 2018 (UTC)
