More than 4,000 took part in the protest, organisers said, streaming through the downtown shopping areas of Shibuya and Omotesando with posters saying “Help us save Myanmar” and “Stop Crimes Against Humanity”.

Tokyo police said they couldn’t comment on how many people attended the event.

The march came as tens of thousands took to the streets of Myanmar on Sunday in a ninth straight day of protests. Several demonstrations have been held in Japan since the Feb 1 coup, mainly by Myanmar residents of Japan.

While the detention of elected leader Suu Kyi is currently due to end on Monday, the coup has been denounced by Western countries, with the US announcing some sanctions on the ruling generals.

While other countries also considering measures, Japan and some other Asian nations are unlikely to cut ties given Myanmar’s strategic importance in the region.

“It is very heart-rending,” said Thant Zaw Htun, 45, originally from Yangon and now an employee at a recruitment agency, referring to the protests in Myanmar.

“I want to go back to Myanmar to join them but cannot because of the situation (travel ban due to the coronavirus pandemic). Instead, I join here today to do what I can do.”

While some carried portraits of Suu Kyi, others wore face masks and even earrings bearing Suu Kyi’s image. Most remained silent rather than shout slogans as they marched in an effort to prevent spread of the coronavirus.

“As a Myanmar national, I absolutely cannot accept the military’s coup in Myanmar,” said Thwe Thwe Tun, 27, who works at a construction company.

“I think all Myanmar people in Japan have the same opinion.”
