The Treaty on Basic Relations Between Japan and the Republic of Korea (Japanese: ; Korean: , , Hanil Gibon Joyak) was signed on June 22, 1965. It established basic diplomatic relations between Japan and South Korea.

Background
As Korea was not a signatory state of the Treaty of San Francisco, it was not entitled to the benefits of Article 14, which stipulated the reparations by Japan. However, by the provisions of Article 21 of that treaty, Korea was entitled to be an authority applied to Article 4, which stated the arrangement of property and claims.

The Treaty was the fruit of the "Korea–Japan Talks," a series of bilateral talks held between South Korea and Japan from October 1951 to June 1965 to normalize diplomatic relations. Over that period of 14 years, a total of seven talks were held.

In his 1974 Nobel Peace Prize lecture, Eisaku Satō explicitly mentioned the Treaty on Basic Relations between Japan and South Korea. He described "the guiding spirit of equality and mutual advantage and the realistic approach of seeking to establish friendship with close neighbors" as significant aspects of the extended negotiations which produced the bilateral agreement.

In October 2018, the Supreme Court of Korea issued a ruling which ordered Mitsubishi Heavy to compensate the victims of forced labor. The company has not done so, with Japan arguing the matter was settled under the 1965 treaty. The Japanese Government has maintained that this ruling, along with the one made on Japan's position in relations to the Korean comfort women ('forced sexual slavery') in January 2021, is a breach of the 1965 treaty.

Terms
The treaty established "normal" diplomatic relations between the East Asian neighbors. The original documents of this agreement are kept respectively by Japan and Korea. The treaty is drafted using English, Japanese, and Korean, each of which is considered authentic. In case of a "divergence of interpretation," the English-language version is deemed to be authoritative and prevailing.

The 1965 Treaty also declared:
It is confirmed that all treaties or agreements concluded between the Empire of Japan and the Empire of Korea on or before August 22, 1910 are already null and void.

Settlements

With the Treaty, the agreements between Japan and Korea concerning the settlement of problems in regard to property and claims and economic cooperation was also signed. 

In accordance to the treaty, Japan supplied South Korea with $300 million grant paid over 10 years, $30 million per year and $200 million in low-interest loans as a 'reparation fee' The official policy of Japanese governments has been that, in regard to war-time property issues and individual claims for compensation, such issues were settled completely and finally by this agreement. 

The 1965 Treaty Article I:
1. To the Republic of Korea Japan shall :
(a) Supply the products of Japan and the services of the Japanese people, the total value of which will be so much in yen as shall be equivalent to three hundred million United States dollars ($300,000,000) at present computed at one hundred and eight billion yen (¥108,000,000,000), in grants [on a non-repayable basis] within the period of ten years from the date of the entry into force of the present Agreement. The supply of such products and services in each year shall be limited to [shall be such] such amount in yen as shall be equivalent to thirty million United States dollars ($30,000,000) at present computed at ten billion eight hundred million yen
(¥10,800,000,000) ; in case the supply of any one year falls short of the said amount, the remainder shall be added to the amounts of the supplies for the next and subse quent years. However, the ceiling on the amount of the supply for any one year can be raised [increased] by agreement between the Governments of the Contract ing Parties.

(b) Extend long-term and low-interest loans up to such amount in yen as shall be equivalent to two hundred million United States dollars ($200,000,000) at present computed at seventy-two billion yen (¥72,000,000,000), which the Government of the Republic of Korea may request and which shall be used for the procurement by the Republic of Korea of the products of Japan and the services of the Japanese people necessary in implementing the projects to be determined in accordance with arrangements to be concluded under the provisions of paragraph 3 of the present Article, within the period of ten years from the date of the entry into force of the present Agreement. Such loans shall be extended by the Overseas Economic Co-operation Fund of Japan, and the Government of Japan shall take necessary measures in order that the said Fund will be able to secure the necessary funds for implementing the loans evenly each year.
The above-mentioned supply and loans should be such that will be conducive to the economic development of the Republic of Korea.

The 1965 Treaty Article II:
1 The High Contracting Parties confirm that the problems concerning property, rights, and interests of the two High Contracting Parties and their peoples (including juridical persons) and the claims between the High Contracting Parties and between their peoples, including those stipulated in Article IV(a) of the Peace Treaty with Japan signed at the city of San Francisco on September 8, 1951, have been settled completely and finally.

Use of loans and grants
The grants and loans provided to South Korea were used for the following projects.

Compensation
There has been a constant call from the South Korean public that Japan should compensate Korean individuals who suffered from Japanese colonial rule. The Japanese government has refused to do so, arguing that it settled issues on a government-to-government basis under the 1965 agreement. The South Korean government has argued that the 1965 agreement was not intended to settle individual claims against Japan for war crime or crimes against humanity as shown by documents presented during the negotiations specifically excluding claims for personal injuries incurred by Japan's violations of international laws. The U.N. Commission on Human Rights has advocated the South Korean government's perspective by defining that the comfort women issue is a matter of human rights; the 1965 treaty only regulated property claims and not personal damages.

In January 2005, the South Korean government disclosed 1,200 pages of diplomatic documents that recorded the proceeding of the treaty. The documents, kept secret for 40 years, recorded that the Japanese government actually proposed to the South Korean government to directly compensate individual victims but it was the South Korean government which insisted that it would handle individual compensation to its citizens and then received the whole amount of grants on behalf of the victims.

South Korean government demanded a total of 364 million dollars in compensation for the 1.03 million Koreans conscripted into the workforce and the military during the colonial period, at a rate of 200 dollars per survivor, 1,650 dollars per death and 2,000 dollars per injured person.
South Korea agreed to demand no further compensation, either at the government or individual level, after receiving $800 million in grants and soft loans from Japan as compensation for its 1910–45 colonial rule in the treaty.

Most of the funds from grants and loan were used for economic development, particularly on establishing social infrastructures, founding POSCO, building Gyeongbu Expressway and the Soyang Dam with the technology transfer from Japanese companies. Records also show 300,000 won per death was used to compensate victims of forced labor between 1975 and 1977.
