The MOJ (Ministry of Justice) posted this ad on Yahoo about taking care to not violate (abuse/infringe) foreigner's human rights. The title of the linked page is 外国人の人権を尊重しましょう (Let's respect foreigner's human rights).
MOJ ad promoting awareness of foreigner's human-rights violations featuring "image characters" 人KENまもる君・人KENあゆみちゃん (human rights Mamoru & human rights Ayumi)
The page goes on to detail that as of 2013 over 9.17 million foreigners have immigrated to Japan, showing a long-term increasing trend. This article goes into detail about the kinds of human-rights violations* faced by foreigners living in Japan (resulting from differences in language, religion, culture, and customs).
And, as the 2020 Olympics have been decided for Tokyo, there will be more and more opportunities for coming into contact with foreigners.
