This series explores topics surrounding women who began their careers in Japan following the implementation of equal opportunities employment legislation in the mid-1980s. With many now reaching retirement age, it is hoped their stories can provide insight and lessons for women in Japan's working world today.

Ayako Sonoda, 59, has forged a successful career as an entrepreneur with a range of successful ventures under her belt. But the CEO of Cre-en, a boutique sustainability consulting firm, hasn't forgotten her roots.

Sonoda’s long tenure in the industry has given her a voice with heft. Having co-authored the book “Sustainability and genuine CSR'' in 2009, she is also a frequent speaker at conferences related to sustainable development goals.
