Japan says it will contribute 20 percent of the 584 million dollar appeal by the United Nations to help Afghan refugees.
Japanese officials said Thursday Tokyo's contribution will be up to 120 million dollars.
U-N Secretary General Kofi Annan made the appeal last week saying the money was needed to help an estimated seven and half million Afghans survive the next six months.
Meanwhile, the Japanese government has announced that it will send aircraft to Pakistan on Saturday to airlift relief supplies for Afghan refugees entering Pakistan.
Japan's Kyodo news agency reports that the Japanese Air Self-Defense Force will send six C-130 transport planes from its Komaki base in Aichi prefecture, with supplies such as tents and blankets.
