The Asian Population and Development Association (APDA) organizes a parliamentarians’ conference in Japan in years when Japan holds the Summit Presidency, with the aim of making policy recommendations to the Summit.

In 2023, at the Global Conference of Parliamentarians on Population and Development Toward the 2023 G7 Hiroshima Summit (GCPPD2023), a declaration was adopted and was directly submitted to Prime Minister H.E. Kishida Fumio. The key elements of population issues addressed in the declaration such as “enhancing gender equality and women’s and girls’ empowerment and effective participation and leadership”, "sexual and reproductive health and rights (SRHR)", and “focusing on the needs of vulnerable groups, such as women and girls, youth, ageing persons, persons with disabilities” were included in the G7 Hiroshima Leaders’ Communiqué.

Also, at the Global Conference of Parliamentarians on Population and Development Toward the 2016 G7 Ise-Shima Summit (GCPPD2016), a declaration was directly submitted to the then Prime Minister H.E. Abe Shinzo, and the recommendations on health including measures for infectious diseases and on women, as stated therein, were reflected in the Summit Leaders’ Declaration.

In 2008, at the G8 International Parliamentarians’ Conference on Population and Sustainable Development, which was held prior to the 2008 G8 Toyako Summit, a parliamentarians’ statement was adopted that put forth a strong message that reproductive health is particularly important for improving maternal and child health in developing countries. As the Chair of the Summit, the then Prime Minister H.E. Fukuda Yasuo directly received the statement, part of which was reflected in the Leaders’ Declaration.
