Japan–Philippines relations
Early Japanese presence in the Philippines. Relations between Japan and the kingdoms in the Philippines date back to at least the pre-colonial period of Filipino history or the Muromachi period of Japanese history. Natives of the Philippines helped shelter Japanese merchants and traders in northern Luzon in 1440, while twenty Japanese traders were also recorded in Manila by 1517. In 1580, while Filipino natives were helping Japanese sailors, a Japanese pirate Tayfusa colonized parts of Cagayan in northern Luzon, establishing his own kingdom. In 1582, the Spanish arrived in Cagayan to colonize it for themselves. This  led to the 1582 Cagayan battles which resulted to the expulsion of Tayfusa's forces. Around 1600, an the area of Dilao, a district of Manila, was a "Nihonmachi" of around 3,000 Japanese or Filipinos with Japanese descent. The term probably originated from the Tagalog term 'dilaw', meaning 'yellow', which describes their general physiognomy. The Japanese had established quite early an enclave at Dilao where they numbered between 300 and 400 in 1593. In 1603, during the Sangley rebellion, they numbered 1,500, and 3,000 in 1606. In the 16th and 17th centuries, thousands of Japanese people traders also migrated to  the Philippines and assimilated into the local population. pp. 52–3 In 1593, Spanish authorities in Manila authorized the dispatch of Franciscan missionaries to Japan. The Franciscan friar Luis Sotelo was involved in the support of the Dilao enclave between 1600 and 1608. In the first half of the 17th century, intense official trade took place between the two countries, through the Red seal ships system. Thirty official "Red seal ship" passports were issued between Japan and the Philippines between 1604 and 1616. The Japanese led an abortive rebellion in Dilao against the Spanish Empire in 1606–1607, but their numbers rose  again until the interdiction of Christianity by Tokugawa Ieyasu in 1614, when 300 Japanese Christian refugees under Takayama Ukon settled in the Philippines. On 8 November 1614, together with 300 Japanese Christians Takayama Ukon left his home country from Nagasaki. He arrived at Manila on 21 December and was greeted warmly by the Spanish Jesuits and the local Filipinos there. The Spanish Philippines offered its assistance in overthrowing the Japanese government by invasion to protect Japanese Catholics. Justo declined to participate and died of illness just 40 days afterward. These 17th-century immigrants are at the origin of some of  today's 200,000-strong Japanese population in the Philippines. More rebellions such as one known as the Tondo conspiracy had Japanese merchants and Christians involved, but the conspiracy was disbanded. Toyotomi Hideyoshi threatened the Spanish to leave or face full scale Japanese invasion, however, this was near his decline and death. The Tokugawa Shogunate rose in power right after. In the 17th century (1633 & 1635), Japan established an isolationist ("sakoku") policy, and contacts between the two nations were severed until after the opening of Japan in 1854. In the 16th and 17th centuries, thousands of Japanese traders also migrated to  the Philippines and assimilated into the local population. In 1888, Filipino national hero Jose Rizal arrived in Japan and had a relationship with Seiko Usui (Osei-san), a daughter of a samurai. Philippines and the Empire of Japan. According to the Spanish diplomat F.E. Reynoso, in 1894 the Japanese offered to buy the Philippines from Spain for 40 million pounds Sterling. However, according to Reynoso this offer was not accepted. According to the scholar C.E. Russell, in 1896 Spain was rumoured to have offered to sell the islands to Japan for $3,000,000 gold dollars, but this offer was rejected . During the 1896 uprising against Spanish colonial rule the 1898 Spanish–American War, some Filipino insurgents (especially the Katipunan) sought assistance from the Japanese government. The Katipunan sought to send a delegate to the Emperor of Japan to solicit funds and military arms in May 1896. The beginning of the uprising coincided with a visit to Manila by the Japanese warship "Kongō", and the leadership approached the captain of the ship in an attempt to buy arms from Japan, but no deal was made. The Meiji government of Japan was unwilling and unable to provide any official support. However, Japanese  supporters of Philippine independence in the Pan-Asian movement raised funds and sent weapons on the privately charted "Nunobiki Maru", which sank before reaching its destination. However, the Japanese government officially acquiesced to American colonial rule over the Philippines, as ratified by the Taft–Katsura Agreement of 1905. During the American period, Japanese economic ties to the Philippines expanded tremendously and by 1929 Japan was the largest trading partner to the Philippines after the United States. Economic investment was accompanied by large-scale immigration of Japanese to the Philippines, mainly merchants, gardeners and prostitutes ('karayuki-san'). Davao that time had  over 20,000 ethnic Japanese residents. In Baguio, Japanese workers represented about 22% of the workforce that constructed Benguet Road (later renamed Kennon Road), so that Baguio later had a significant Japanese population. By 1935, it was estimated that Japanese immigrants dominated 35% of Philippine retail trade. Investments included extensive agricultural holdings and natural resource development. By 1940, some 40% of Philippine exports to Japan were iron, copper, manganese and chrome. During World War II, immediately after the attack on Pearl Harbor, Japanese forces invaded and quickly overcame resistance by the United States and Philippine Commonwealth military. Strategically, Japan needed the  Philippines to prevent its use by Allied forces as a forward base of operations against the Japanese home islands, and against its plans for the further conquest of Southeast Asia. In 1943, a puppet government, the Second Philippine Republic, was established, but gained little popular support, primarily due to the Imperial Japanese Army's brutal conduct towards the Philippine civilian population. During the course of the Japanese occupation, and subsequent battles during the American and Filipino re-invasion, an estimated one million Filipinos died, giving rise to lingering anti-Japanese sentiment. More than a thousand Filipino "comfort women", composed of  mothers, girls, and gay men, were forcibly taken by Japan to serve at their sex slave camps during the occupation. Hundreds of heritage cities and towns throughout the country lay in ruins due to intentional fire and kamikaze tactics imposed by the Japanese and bombings imposed by the Americans. Only a single heritage town, Vigan, survived. The government of the Empire of Japan never gave any compensation for the restoration of Filipino heritage towns and cities. While the United States only gave minimal funding for two cities, Manila and Baguio. A decade after the war, the heritage landscape of the  Philippines was never restored due to a devastated economy, lack of funding, and lack of cultural experts during the time. The heritage zones were effectively replaced by old shanty houses and cement houses with cheap plywood or galvanized iron as roofs. According to a United States analysis released years after the war, U.S. casualties were 10,380 dead and 36,550 wounded; Japanese dead were 255,795. Filipino deaths, on the other hand, has no official count but was estimated to be more than one million, an astounding percentage of the national population at the time. The Philippine population decreased continuously for the  next 5 years due to the spread of diseases and the lack of basic needs, far from Filipino lifestyle prior to the war where the country used to be the second richest in Asia, ironically, next only to Japan. Post-war relations. The Philippines was granted independence in 1946, and was a signatory to the 1951 San Francisco Peace Treaty with Japan. The two countries had a long, protracted process about postwar reparations before formalizing diplomatic relations. As detailed in the Japanese Instrument of Surrender, the authority of the Japanese Emperor and Japanese government was subjected to Supreme Commander for  the Allied Powers (SCAP) Douglas MacArthur. The Far Eastern Commission (FEC) was also formed. It was a body composed of Allied members tasked with formulating the policies of occupied Japan which would be enforced by the SCAP. Carlos P. Romulo represented the Philippines in this body. Japan entered into negotiations with several countries for postwar reparations. The US policy was to have Japan pay for reparations in the form of goods or existing capital equipment and facilities. According to the US Department of State, this was to ensure Japan could continue its demilitarization process, as these were not necessary neither  for the occupation forces nor for a peaceful Japanese economy. The United States sought to form the Inter-Allied Reparations Committee which would focus on policies for reparations. However, as this involved the contested territories of Manchuria, Sakhalin and the Kuril Islands, the then-Soviet Union opted to veto. In 1947, the US again pushed this agenda with the Advance Reparations Transfer Program, which would focus on early reparations for four countries, chosen for their stance against Imperial Japan and their assistance to the United States. These were, namely: the Philippines, China, Holland (representing Indonesia) and Great Britain (representing Burma  and Malaysia). The discussion of reparations took an abrupt turn due to the intensifying spread of Communism in Greece and Turkey during the Cold War. This prompted the move of the United States to pursue the Containment Policy, aimed at stopping the spread of communism worldwide. One of the advocates of the Containment Policy, George F. Kennan, suggested the immediate rehabilitation of Japan's industrial and military capacity in order to best assist the US in countering communism in Asia. This ran counter to the initial position of the United States in regards to reparations, but after Mao Zedong took  control of China and the onset of the Korean War, Japan was directly exposed to the threat. The United States sent survey missions to Japan to assess the industrial capacity of the country and agreed with Kennan's suggestion. The United States ended the Advance Reparations Transfer Program, to which the Philippines, through Romulo and Foreign Affairs Undersecretary Felino Neri, objected. Countries involved also started working towards a peace treaty. Romulo and Neri put forth the Philippine position that they recognize the threat of Communism, as the country itself faces an insurgency of their own, and that they also welcome  the Peace Treaty to ensure Japan can actively participate in negotiations. However, they reiterated their concern for reparations. When the 1951 San Francisco Peace Treaty was signed, Romulo lamented that it "fails to provide for reparations in the form and manner [they] desire." However, he conceded that it was still a step in the right direction as it would be even more detrimental for the Philippines not to sign it. Furthermore, he expressed optimism as Japanese Premier Shigeru Yoshida "solemnly pledged to [them] that Japan will do all that is humanly possible to repair the damage it has done to  the Philippines." Diplomatic relations were normalized and re-established in 1956, when the war reparations agreement was finally concluded. By the end of the 1950s, Japanese companies and individual investors had begun to return to the Philippines. Japan and the Philippines signed a Treaty of Amity, Commerce and Navigation in 1960, but the treaty did not go into effect until 1973. Relations during the Marcos Administration. Hirohito met with President Ferdinand Marcos in a state visit by the latter to Japan in 1966 - a year after Marcos' election and about six years before Marcos declared martial law. In 1972, Marcos  abolished the Philippine legislature under martial law, and took on its legislative powers as part of his authoritarian rule. He ratified the Treaty of Amity, Commerce and Navigation ten days prior to a visit of Japanese Prime Minister Kakuei Tanaka. By 1975, Japan had displaced the United States as the main source of investment in the country. Marcos administration projects put up during this time include the Philippines-Japan Friendship Highway which included the construction of the San Juanico Bridge, and the Research Institute for Tropical Medicine. However, many of these projects were later criticized for helping prop up the  corrupt practices of the Marcos administration, resulting in what became called the Marukosu giwaku (マルコス疑惑), or ""Marcos scandal"", of 1986. Japan ODA scandal. When the Marcoses were exiled to Hawaii in the United States in February 1986 after the People Power Revolution, the American authorities confiscated papers that they brought with them. The confiscated documents revealed that since the 1970s, Marcos and his associates received commissions of 10 to 15 percent of Overseas Economic Cooperation Fund loans from about fifty Japanese contractors. This revelation became known as the , or ""Marcos scandals"", and had to be addressed by the administrations of  succeeding presidents Corazon Aquino and Fidel V. Ramos. The Japanese government discreetly requested the Philippine government to downplay the issue as it would affect the business sector and bilateral relations. The lessons from the Marcos scandals were among the reasons why Japan created its 1992 ODA Charter. After 1986. Japan remained a major source of development funds, trade, investment, and tourism in the 1980s, and there have been few foreign policy disputes between the two nations. When Philippine President Corazon Aquino's administration was installed as a result of the People Power Revolution, Japan was one of the first countries  to express support for the new Philippine government. Philippine President Corazon Aquino visited Japan in November 1986 and met with Emperor Hirohito, who offered his apologies for the wrongs committed by Japan during World War II. New foreign aid agreements also were concluded during this visit. Aquino returned to Japan in 1989 for Hirohito's funeral and in 1990 for the enthronement of Emperor Akihito. Regarding the voting of the Philippine Senate to extend a treaty allowing the stay of U.S. bases in the Philippines, Japan was in favor for the extension of the defense treaty. In fact, some of  its officials including Ambassador Toshio Goto, Foreign Minister Taro Nakayama and Prime Minister Toshiki Kaifu expressed public disagreement on a negative vote on the extension. However the Philippine Senate rejected the extension of the defense treaty despite extensive lobbying for its extension by the first Aquino administration, even calling for a referendum regarding the matter. In 1998, 246,000 Filipinos lived in Japan. Upon the withdrawal of most American troops in the Philippines, relations between the United States and the Philippines remained strong as assured by US President Bill Clinton to Philippine President Fidel V. Ramos during the latter's visit  to Washington on 21 November 1993. Likewise the Philippines-Japan relations were strengthened with Japan filling the gap the United States left. Even before Ramos became president he held talks with the Japan Ministry of Defense to improve defense relations as Defense Secretary under Corazon Aquino's administration. During a meeting with President Ramos in 1993, Japanese Prime Minister Kiichi Miyazawa reiterated his apology for his country's war crimes committed against the Philippines and its people during World War II and would consider the best way to address the issue. The Ramos administration also supported Japan's bid to  become a permanent member of the United Nations Security Council, together with Germany. Japan also became the top donor of aid to the Philippines, followed by the United States and Germany. Japan also contributed the largest amount of international aid to the Philippines after the latter suffered from the 1990 Luzon earthquake and 1991 Mount Pinatubo eruption. In 2009, Japan supported an NGO which repatriated the skeletons of Japanese soldiers from World War II. The NGO repatriated numerous skeletons of indigenous Filipino ancestors, along with few Japanese skeletons, causing rallies in the Philippines. Japan ended its support for the skeleton  repatriation program afterwards, however, the remains of the indigenous Filipinos were never sent back to the ancestral communities they were stolen from. Strategic relationship between the two countries has been strong recently. Japan supports the resolution of the Islamic insurgency in the Philippines. In 2013, Japan announced it would donate ten ships valued at US$11 million to the Philippine Coast Guard. Japan and the Philippines share a "mutual concern" on China's increasing assertiveness in its territorial claims. In November 2015, the Philippine government and the Japan International Cooperation Agency (JICA) signed a $2-billion loan agreement for  the JICA to fund part of the construction of a railway system between the Tutuban railway station in Manila to Malolos, Bulacan in the Philippines, which is targeted to become the country's largest railway system. According to the Philippine Department of Finance, the agreement was the JICA's "largest assistance ever extended to any country for a single project." On February 29, 2016, Japan Signed a pact to supply defense equipment to Philippines. The agreement provides a framework for the supply of defense equipment and technology and will allow the two countries to carry out joint research and development  projects. On April 3, 2016, Japanese training submarine JS Oyashio, along with two destroyers JS Ariake and JS Setogiri docked at the Alava Pier in Subic Bay for a three-day goodwill visit. In early May 2016, plans to spearhead a Japan-Philippine Mutual Defense Treaty was one of the key defense plans of the government if Mar Roxas wins the presidency. However, the May 10 presidential elections resulted to the presidential victory of Rodrigo Duterte. In October, 2016, talks about the defense treaty was revived when the government stated that the possible treaty 'may' be discussed by Duterte and  Abe during Duterte's first official visit to Japan. The visit however resulted in no talks regarding the possible treaty after Duterte decided to ally himself with China. In 2017, civilian groups in the Philippines and other countries joined forces to push for the inscription of "Voices of the ”Comfort Women”" in the UNESCO Memory of the World Programme. The inscription, however, was blocked by Japan. On the same year, a blindfolded Filipina comfort women statue was erected in Manila, the capital of the Philippines, by surviving Filipino comfort women and their supporters. By April 2018, the comfort woman statue  was removed from the capital after Duterte met with Japanese diplomats. The statue was scheduled to be reinstalled at front of Baclaran Church, but was allegedly stolen. Japanese Official Development Assistance (ODA) to the Philippines. Japan has been the Philippines' biggest source of bilateral Official Development Assistance since 2001, with its ODA loans to the Philippines accounting for 72 percent of the Philippines’ total bilateral loan portfolio as of 2021. Japan disburses Official Development Assistance to the Philippines through the Japan International Cooperation Agency (JICA) when the ODA is in the form of projects, and directly through the Embassy of  Japan to the Philippines in the case of non-project grant aid.
