The number of xenophobic rallies in which ultra-right-wing groups use discriminatory language has dropped by nearly half in the 11 months since the Diet enacted a law to deter hate speech, the National Police Agency said.

While statistics show some positive impact from the law, legal experts are starting to point out its limitations because groups are finding ways to circumvent it by modifying their language at rallies to avoid obvious epithets but still express the same kind of bigotry.

From June 3, 2016, through the end of April, police nationwide tallied 35 demonstrations involving hate speech versus 61 in the same period a year earlier.
