Anti-Trump Protesters in Japan Urge peace in East Asia Region

"Abe and Trump will talk about launching a war on the Democratic People's Republic of Korea (North Korea) ," said Hiroyuki Yamamoto, secretary-general of International Labor Solidarity Committee. "Japan's Constitution forbids the country from using force to resolve international disputes."

Trump arrived at the US Yokota Air Base on the outskirts of the Japanese capital on Sunday.

Abe has reiterated his full backing for Trump's policy of putting all options, including military ones, on the table in dealing with the North Korea, which was expected to top the agenda of the two leaders' talks on Monday.

Sunday's protest in Tokyo was also against Abe's efforts to rewrite the Constitution. The Abe administration plans to add a clause on making explicit the status of the country's self-defense forces, as the Japanese military is known, to Article 9, which prohibits Japan from maintaining land, sea and air forces.

Trump met Japanese Emperor Akihito and Empress Michiko on Monday ahead of his talks with Abe.

Tokyo is the first leg of Trump's first visit to Asia since he was inaugurated in January. The trip will also take him to the Republic of Korea, China, Vietnam and the Philippines.
