US President Donald Trump departed for Tokyo on Monday, where he was scheduled to meet Japan’s emperor and newly elected Prime Minister Sanae Takaichi as part of an Asia trip aimed at securing trade deals, investment and increased defence spending.

Trump, on his longest journey abroad since taking office in January, announced a slew of deals with Southeast Asian countries and oversaw the signing of a ceasefire agreement between Thailand and Cambodia during his first stop in Malaysia.

His trip is expected to conclude in a summit with Chinese President Xi Jinping in South Korea on Thursday, where the world’s two largest economies will seek to avert an escalation of their trade war.

While Trump has already landed a $550 billion investment pledge from Japan in exchange for respite on punishing import tariffs, Takaichi is hoping to further impress Trump with promises to purchase US pickup trucks, soybeans and gas.

“Just leaving Malaysia, a great and very vibrant Country. Signed major Trade and Rare Earth Deals, and yesterday, most importantly, signed the Peace Treaty between Thailand and Cambodia. NO WAR! Millions of lives saved,” Trump said in a post on Truth Social shortly before his departure.

“Such an honour to have gotten this done. Now, off to Japan!!!”

Takaichi, who became Japan’s first female premier last week, told Trump that strengthening their countries’ alliance was her “top priority” in their first phone call on Saturday.

Thousands of police have been deployed across the Japanese capital for Trump’s arrival, with the arrest of a knife-wielding man outside the US embassy on Friday and an anti-Trump protest planned in downtown Shinjuku adding to the tension.

Commerce Secretary Howard Lutnick and his Japanese counterpart Ryosei Akazawa, architects of the tariff deal agreed in July, are set to hold a working lunch on Monday. Treasury Secretary Scott Bessent, travelling with Trump alongside Secretary of State Marco Rubio, is also expected to meet with his new counterpart, Satsuki Katayama, for the first time.
