The death of George Floyd, a 46-year-old African American man, while pinned face down by three Minneapolis police officers has sparked angry demonstrations and marches across the United States and around the world. In Japan, similar marches against racism and police brutality are planned in some cities this weekend.

For those thinking about heading to a demonstration, here are some things for reference in either planning, or participating, in public protests or marches in Japan — as well as some do’s and don’ts — based on this reporter’s 25 years of covering dozens of protests throughout Japan and internationally.

Article 21 of the Constitution guarantees freedom of assembly and association as well as freedom of speech. Street demonstrations and public protests are, however, still subject to regulations. Each prefectural police department requires permits for the use of public roads and parks for a march or rally.
