Managing Director

After establishing ACE, Tomoko went on to complete her Masters at the School of Oriental and African Studies in London. Having then developed a career in development consulting alongside her role at ACE, Tomoko has a strong background in consultation services for businesses which she further strengthened by completing the SA8000 basic social auditor training course. Since 2005, she has fully committed her time to ACE, and is hands-on in the organisation's project in Ghana, the Social Business team, consumer education and the promotion of international cross-sector collaboration and ethical business. Most recently, she contributed her expertise while working closely with the Ghanaian government to develop the “Protocols and Guidelines for Establishing Child Labour Free Zones in Ghana” that was officially launched in March 2020. 



Yuka spent her childhood from the age of 14 to 16 years, living in Boston, U.S. After getting into Sophia university, Japan, she studies abroad in Miami University for 2 terms. Before returning to Japan, she travelled via Mexico where she came face-to-face with children who were out begging on the streets. This encounter led her to focus her Masters thesis on child labour and education for her MA in International Public Policy at Osaka University. She finally felt her real call to action in 1997, when Kailash Satyarthi was architecting the first ever Global March Against Child Labour in 1998, and wanted to initiate Japan’s participation.


She has gained experience in various roles including as an interpreter and serving as a fellow at Winrock International, working on the Best Practices Report for the CIRCLE project (2006). Since 2007, she has been working full-time for ACE. She has worn many hats, including as an adhoc lecturer at J.F. Oberlin University, leading the civil society campaign for the 2008 G8 Summit, and acting as the Chair of the 2019 Civil 20 Summit which led civil society organization's advocacy for the G20 Summit in Osaka. She currently serves as a Board Member of the Japan Ethical Initiatives, and of JANIC (Japan NGO Center for International Coorperation).



Deputy Managing Director

Yukako became interested in international NGO work during her time at university. She visited cities and villages across India where she saw first hand the harsh reality of the poverty within which children were living, a world so far removed from the environment she had grown up in. Education, she realized was the key to changing society. From then, she began to study social work in India and continued to build a career in the international NGO field.
"I am Deputy Managing Director, and I am also in charge of our field projects that withdraw children from child labour and support establishing independent villages that protect children's rights. I further promote children's rights and socially-responsible business relating to the cotton industry in Japan. "


Chief of Advocacy

"I took part in the Global March against Child Labour in Geneva in 1998, and have been working on the elimination of child labour since then. Mostly, my work focuses on research and managing projects regarding child labour and non-formal education, in particular in India and Pakistan.

At ACE, I am in charge of advocacy and wish to relay the voices of children in difficult circumstances to political leaders in Japan and across the globe in order to achieve social change. My aim is to create a world where every child, regardless of where they are born, can go to school, play and live a happy childhood."



PR & Digital Outreach

After completing her student exchange in the US and graduating from university, Masami worked in web design in New York. Following her return to Japan, she happened across a book about children working in a carpet factory in India. This was the seemingly fortuituous moment that opened her eyes to the injustice of child labour. She joined ACE in 2016 and is now in charge of Digital Outreach. 

"Everyday I aspire to work towards Kailash's notion of "Globalize Compassion", and get even just one more person to realise and care that child labour is an issue that is linked to them." 



PR & Engagement 

Mihoko has been with ACE since 2009, having begun in IT she decided to move to the NGO field. 
Currently I look after the organization's database and the sale of our ethical chocolates. 


Ghana Project Manager

Akira completed his master's at the Graduate School of International Development at Nagoya University, Japan. After working as an intern at Amnesty International at the Africa - Japan Forum, he was assigned to Ghana and Uganda as a Japan Overseas Cooperation Volunteer. He worked at the Japan Association for International Collaboration of Agriculture and Forestry (JAICAF), the National Agricultural Experimental Station Rehabilitation Project in Afghanistan, and Oriental Consultants Co., Ltd. (a local Operation Coordinator for infrastructure projects in Uganda).



India Project Manager

During her time at university, Yuko had the opportunity to do an internship with an Indian NGO that rescues and protects the rights of street children. When she returned to Japan, she took part in a study share session tour in India organized by ACE, which further fuelled her interest in child labour.

"I have been working with ACE since 2015, and have been fortunate enough to be in charge of our community projects in the cotton hubs of India. I also promote organic and fair trade cotton in Japan, speaking at events at schools and for the public to educate consumers. We are working to encourage people in Japan to believe that child labour can be eliminated and to take action.


While working as an ACE staff member, I have seen children who have escaped child labour and have changed their lives. Children who have escaped child labour will begin to show a dazzling smile and talk about themselves with confidence."



General Affairs & Accounting 

"In some places in the world, just being a girl disqualifies you from an education". This was the phrase written on a UNICEF poster that spurred my unfading interest in international development. However, it was the pair of sparkling eyes belonging to the girl photographed in the poster that truly left an impression on me. A girl who had been given the opportunity to go to school. I thought, I want to help bring more joy like that into the world."

Awareness Team

Ayaka spent her middle school years living in New Delhi, India, and was shocked at having seen children her age and younger work on a daily basis. During her time at university, she volunteered and participated in the student team at ACE. After graduating from Meiji Gakuin University, Faculty of International Studies, she worked as an instructor at a cram school and finally joined the team at ACE in 2015. She conducts awareness-raising and policy advocacy activities related to child labour, as well as running awareness-raising activities for the public through exhibitions, workshops and lectures. She has a wealth of experience in conducting workshops using ACE-created teaching materials, and serves as a facilitator for many organisations, consumer groups and educational institutions.




Social Business Consultant

"Born and raised in a peaceful town in the mountains of Tamba, I had always dreamed of playing an active part on the world stage from an early age. While working for a trading company, I began helping with outsourced production and purchase of cotton clothing in India and Southeast Asia. At that time, the words "fair trade" and "ethical fashion" did not exist, and consumers did not give a second thought to the source of materials.

However, many decades later, I became an Ojichan (old guy) and became aware of the child labour problem. I saw the story of the exploitation of children on ACE's website and it shook me. I was left shaken by knowing the existence of these children and realised I need to help. I now know and fully recognize that the problem of poverty hinders the sustainable development of the world and that child labour leads to on-going poverty and  increasing  disparity.

As an ACE representative, I would like to create opportunities for other people who, like myself, had not been aware of the what was going on in the supply chain and take action together".



Chief of Social Business 

"As a Japanese citizen, I was proud to have worked for a manufacturer for many years, selling Japanese products and being recognized for their high quality overseas. While production bases are moving overseas, where labour costs are low, we see that things that would not be able to occur in the countries where the head office of companies are slip through the weaker laws and regulations in place in the developing nations. This spurred an ethical dilemma for me. 

I wanted to conduct profitable activities that did not sacrifice or exploit people. As such, I left my previous job to study development economics. After completing my MBA and my PGDip in Development Study and Research, I became interested in human rights issues in the supply chain and decided to join the ACE team in 2018. In order to eliminate child labour caused by the economic and social exploitation of the most vulnerable in society, I aim to work together with companies to improve their social value and make money while building a better society."



Chief of Awareness

I had a vague idea that I wanted to work in international cooperation someday, but it was when I had my own children that really ignited my passion to protect children and their right to smile. 

Child labour is very much closely related to our daily life in Japan. That is why I believe that if we change our behaviour, we can change the problem. Now that I'm a mum, I'm wondering if there is some previously invisible strategies of international collaboration that can be uncovered from my new perspective.  Why don't you join me in uncovering the full potential of "International Cooperation Utilising Mum's Power"?



Fair Charge Project Researcher 

"After completing my Masters in Gender, Race, Sexuality and Social Justice at the University of British Columbia, Vancouver, I moved to Japan. 

I initially started as an Intern with ACE to build experience and leverage my research skills. Whilst I support the PR & Engagement team with their international communications, I mostly conduct research for the Social Business team - including mapping CSR activities in the cacao industry and human rights violations in the mineral supply chain.

ACE approaches child labour with systemic solutions, and what I like most about the organization is their ability to foster cross-sector dialogue and implement change from the source of a supply chain all the way to the consumer to enable the longer-term elimination of child labour."




I was a high school student when I became interested in child labour because I was shocked to see a child working at a cacao farm. After entering university, I actively participated in a fair trade coffee student group.


I wanted to know how ACE was working collaboratively with companies to address child labour, so I applied for an ACE internship. As an intern, I work to encourage more people to participate in action to eliminate child labour, such as managing events, creating teaching materials to use at events, and handling  the social media for Yuru Chara.
