Enraged about layoffs and labor practices at Japanese companies in the country, about 2,000 Indonesian workers rallied in front of the Japanese Embassy in Jakarta on Wednesday.
Similar rallies were also staged in the city at the embassies of Italy, Malaysia and South Korea.
Police, who dispatched about 8,200 officers, estimated that between 5,000 and 7,000 workers in all took part in the rallies, with more expected to join later.
