Rent application denials, Japanese-only recruitment and racist taunts are among the most rampant forms of discrimination faced by foreign residents in Japan, according to the results of the country's first nationwide survey on the issue, released Friday.

The unprecedented survey of 18,500 expats of varying nationalities at the end of last year paints a comprehensive picture of deeply rooted discrimination in Japan as the nation struggles to acclimate to a recent surge in foreign residents and braces for an even greater surge in tourists in the lead-up to the 2020 Tokyo Olympics.

It also represents the latest in a series of fledgling steps taken by Japan to curb racism, following last year's first-ever video analysis by the Justice Ministry of anti-Korea demonstrations and the enactment of a law to eradicate hate speech.
