After Manila, Abe will travel to southern Davao city, Duterte's hometown where Yasay said the president may host breakfast for the Japanese premier at his home.
Abe said he hoped the Philippines and China would act based on the ruling last July of the UN-backed tribunal in The Hague which concluded that China's claim over nearly the entire South China Sea had no legal basis.
Abe later left for Australia, where he is to meet the country's Prime Minister Malcolm Turnbull.
Japanese Prime Minister Shinzo Abe and Philippine President Rodrigo Duterte have affirmed their agreement on the importance of the U.S. contribution to the peace and prosperity of the Asia-Pacific region ahead of the inauguration of Donald Trump amid uncertainty about the incoming USA president's foreign policy.
Japan's Prime Minister gets a taste of Davao hospitality
During his visit Abe has committed a one-trillion-yen aid package for the Philippines. He was also the first head of government to visit Davao, the largest city in Mindanao.
Abe has nevertheless been supportive of improving ties between Manila and Beijing in light of the arbitral court ruling that invalidated China's claim to almost the whole of the South China Sea. Mr Abe, 62, is the first head of state to visit since Mr Duterte, 71, took office in June 30 past year. "But for a very effective and comprehensive development of the Philippine economy, I'd like to emphasize that the business and investment-friendly environment inside of the Philippines is necessary", he said in a press briefing in Malacañang on Thursday night. Duterte reacted angrily previous year when the administration of US President Barack Obama aired concerns about extrajudicial killings in Duterte's anti-drug campaign.
"We hope to fast-track the delivery to the Philippines of key assets already in the pipeline and the acquisition of new ones", Duterte said.
About two dozen activists, led by four Filipino women who were forced into sexual slavery by Japanese troops in World War II, protested outside the Japanese Embassy, demanding justice for their sufferings in a call that has largely been muted by the blossoming relations of the Asian neighbors.
