Deport all Vietnamese out of Japan. They are extremely dirty people. Just search on Duckduckgo.com/Bing.com/search.Yahoo.com with keywords "Vietnamese stealing in Japan", "Vietnamese are thief", "Vietnamese pickpocket", "Vietnamese are rude", "Vietnamese are scammers", you will be surprised. But my experience is limited

So, you don't like Vietnamese people... personally I've always found them hardworking, intelligent and friendly, but my experience is limited.
