In appreciation of the good work done by the Motamar AI-Alam Al-Islami (World Muslim Congress) in promoting inter-religious cooperation between Muslims and the followers of other religions, the Nikkyo Niwano Peace Foundation presented its coveted Annual Award to the Motamar AI-Alam Al-Islami through its then Secretary-General, late Dr. Inamullah Khan, in 1987.

Rev. Niwano addressed the first special session of the UN General Assembly in New York in 1978 which was devoted to Disarmament. He said to the UN General Assembly in Japanese: "Instead of taking risks with arms, please take for peace. "In April 1979, in a glittering ceremony in London (which I had the honour of attending as a Pakistani diplomat), the highly prestigious temptation Foundation Prize for Progress in Religion was conferred on Rev. Nikkyo Niwano. On the request of certain US Senators and the cooperation of the Iranian Government, Rev. Niwano took a keen interest in a dialogue for the release of the American hostages in Iran in late 1979 and 1980 as result of which their release was speeded up. In September 1982, Rev. Nikkyo Niwano visited the USSR at the invitation of the Christian Orthodox Church and met Soviet leaders, urging a ban on nuclear weapons. Earlier, his organisation, Rissho Kosei-Kai had collected 27 million signatures to a petition to the UN calling for disarmament and abolition of nuclear weapons. Rev. Niwano was profoundly grieved when his wife of 64 years, the gracious Mrs. Naoko Niwano died in April 1994.

A high watermark in Rev. Niwano's life was reached when on November 5, 1994, he delivered the opening address of the WCRP's Sixth Assembly held at the Vatican's Synod Hall as its Honorary President and Pope John Paul II sat next to him. In March 1998, Rev. Nikkyo Niwano was extremely happy when his organisation Rissho Kosei-Kai celebrated its 60th anniversary and many world religious leaders present in the august gathering congratulated Rev. Nikkyo Niwano and his organisation. In March 1999, Rev. Niwano published his autobiography in Japanese; it is being rendered into English and other languages.

Rev. Nikkyo Niwano designated his son, Rev. Nichiko Niwano as his successor and future President of the Rissho Kosei-Kai in 1991. Rev. Nichiko led the funeral prayers in Tokyo for his late father on October 4, 1999 and expressed his determination to continue the god work launched by his father in the service of humanity. Rev. Nikkyo Niwano made concerted efforts to build bridges of understanding between the Japanese and the Americans, between Muslims and Jews in the Middle East, and received a large number of coveted awards from many international and religious bodies for his services to mankind and the living faiths.

I had the pleasure of meeting Rev. Nikkyo Niwano in the Asian Conference on Religion and Peace in Singapore in February 1976. My co-delegate was the late Chief Justice Hamoodur Rahman. With Mr. Niwano's blessing, the ACRP accepted my resolution for making ACRP a permanent body. I helped draft its Constitution. In April 1979, while serving at the Pakistan Embassy in London I met Rev. Niwano at a glittering ceremony in London when the famed Temptation Prize was conferred on him. In August-September 1979, I met Rev. Nikkyo Niwano many a time during the World Conference on Religion and Peace held at the Princeton University in New Jersey in the USA. I also met Mother Teresa and was a member of the Conference Declaration Drafting Committee. Some ideas for it were given to me by Rev. Nikkyo Niwano. My co-delegate from Pakistan was Mr. A. K. Brohi, a former law Minister of Pakistan. In my letter of condolence to Rev. Nichiko Niwano on the death of his illustrious father, I wrote on Jan. 7, 2000 Rev. Nikkyo Niwano was one of the very great men of the 20th Century and one of its revered immortals. May Divine Providence bless his soul with the peace of the Heavenss and may his message of peace, compassion and goodwill among men and women of all climes, and tongues continue to echo in every part of the world….. I still see him with my mind's eye, an epitome of human greatness and divine qualities o head and heart. Rev. Nikkyo Niwano will live eternally in the greatness of his good deeds and the nobility of his message of concord to humankind."
