Japan Special Fund and Trust Funds

Japan has been the top contributor to ADB's Special Funds, such as the Asian Development Fund, ADB Institute, and Japan Special Fund.

Asian Development Fund


Japan is the largest contributor to the Asian Development Fund (ADF), ADB’s window for concessional lending to its borrowing members. Its contributions to the ADF (including committed funds at exchange rates per resolution) totaled $11.96 billion as of 2014.

ADF is a partnership between ADB and its member countries. Financed mainly by contributions of ADB members, ADF supports the economic and social development of the most vulnerable countries in the region. More

This special fund meets the operating costs of the ADB Institute (ADBI), a key Asian think tank established in 1996 as a subsidiary body of ADB. The ADBI Fund is administered by ADB in accordance with the statute of ADBI. ADBI is currently funded by Japan, Australia, and the Republic of Korea.

In June 2014, the Government of Japan committed its 23rd contribution for ¥672.1 million ($6.6 million equivalent) and in December 2014, committed its 24th contribution for ¥672.1 million ($5.6 million equivalent). More

Japan Special Fund 


The Japan Special Fund (JSF) was established in 1988 when ADB, acting as the administrator, entered into a financial arrangement with the Government of Japan, which agreed to make the initial contribution to help ADB’s developing member countries (DMCs) restructure their economies and broaden the scope of opportunities for new investments, mainly through technical assistance operations.

As of December 31, 2014, Japan’s cumulative contribution to the fund since its inception in 1988 amounted to ¥112.9 billion ($973.7 million equivalent), comprising regular contributions of ¥94.8 billion ($822.9 million equivalent) and supplementary contributions of ¥18.1 billion ($150.8 million equivalent). The uncommitted balance, including approved technical assistance projects that are not yet effective, was $65.5 million as of December 31, 2014 ($62.6 million as of December 31, 2013). More

Technical Assistance Special Fund 


Japan also contributes to the Technical Assistance Special Fund (TASF), which provides grants to borrowing members to facilitate the flow and efficient utilization of development finance to DMCs and to enhance their development capacity. As of 2014, committed contributions of Japan to the TASF amounted to $495.34 million.
