The Japan Environment and Children's Study (JECS), a birth cohort study involving 100,000 parent-child pairs, was launched in 2011 in order to evaluate the impact of various environmental factors on children's health and development. The concept plan of JECS was published in March 2010 after three years of development within expert groups and public discussions about the research hypotheses and aims. Pilot studies started in 2008 in four universities, and samples from two preceding cohorts (Hokkaido and Tohoku) are also used for establishing exposure measurement protocols. The recruitment of hundred thousand pregnant women was achieved in March 2014. Health outcomes and exposure measurements will continue until the participating children become 13 years old.
