In a bid to curtail hate speech ahead of the 2020 Games, Tokyo on Friday adopted an anti-discrimination ordinance aimed at protecting the LGBT community. The rule is the first ordinance at the prefectural level to contain a stipulation prohibiting discrimination against LGBT people and other sexual and gender minorities.

The Tokyo Metropolitan Assembly approved the ordinance at its regular session held Friday, despite criticism that there had been insufficient debate over potential conflicts between the measure and laws to protect free speech.

The goal of the ordinance, which is scheduled to take effect in April, is to use edifying campaigns and education to realize the Olympic Charter goal of respect for human rights.

The charter is a set of rules and guidelines documenting the fundamental Olympic principles. It states: “The enjoyment of the rights and freedoms set forth in the Olympic Charter shall be secured without discrimination of any kind, such as race, color, sex, sexual orientation, language, religion, political or other opinion, national or social origin, property, birth or other status.”

In 2014 the International Olympic Committee added an anti-discrimination clause for hosts, after the global controversy that surrounded the Sochi Games following Russia’s passage of an anti-gay law in 2013.
