Anti-whaling activists will hold demonstrations in Tokyo and other cities worldwide including Canberra this weekend.
Protesters are expected to gather in the Japanese capital to call for an end to the annual state-sponsored whaling mission to the Southern Ocean, due to start in the next few weeks, and to the slaughter of dolphins in Taiji.
Action for Marine Mammals are planning to march through Shibuya and Harajuku on Saturday, group spokesman Hideaki Nagai told AFP.
Demonstrations are planned on the same day in Canberra, London, Los Angeles, Miami, Milan, Sao Paulo, Vancouver, and a city in Texas, he said. ''We don't think whaling and dolphin hunting are necessary in Japan, although we are not against indigenous people's rights to hunt marine mammals,'' he said.
