Hundreds of demonstrators gathered in front of the Hong Kong Economic and Trade Office in Tokyo's Chiyoda Ward on Thursday to show support for those in Hong Kong speaking out against a controversial extradition bill that has sparked street protests that have turned violent.

The organizer said more than 300 people joined the rally in Tokyo.

A massive protest took place in Hong Kong on Sunday over a bill introduced by pro-Beijing leaders that would allow extraditions to mainland China.
