Yoshiichi Tokuda

FIFA World Cup and BoP ("Base of the Pyramid") were the two keywords that launched Tokuda’s involvement with Open Energy Systems. Despite the enormous popularity of soccer in Africa, people in unelectrified areas are often unable to watch their own national team play on TV. To share the World Cup experience with such people, Tokuda’s team created a 2009 project in collaboration with JICA to hold public viewings in Ghana. Then, in 2010 Tokuda took part in Sony CSL's Geo Project, taking solar panels and batteries to unelectrified communities in Ghana for more public viewings. Supported by JICA from 2011 to 2013, he worked on an off-grid electrification project in Ghana, applying the OES concept to demonstrate its bottom-up business potential for the developing world. Since 2013, he has been doing empirical research on DCOES (DC-based OES) at the Okinawa Institute of Science and Technology campus in association with Okisokou Co. Ltd.

OES Energy / Sustainability / BOP






At Tohoku University's Graduate School of Information Sciences, Tokuda’s research on design support systems using formal specification languages led to a doctorate in Information Sciences. After a spell as an assistant at the Research Institute of Electrical Communication, he then joined Sony, working in the Human Interfaces Laboratory on upper process improvement for usability engineering and software design. Tokuda then transferred to the Creative Center, where he was involved in sustainable design and projects related to the FIFA World Cup. At Sony CSL, he has been involved in two projects: a preliminary joint study with JICA promoting BOP business linkages called Off-Grid Electrification for Unelectrified Areas of Ghana (2011-2013), and empirical research on distributed DC power control for deploying Open Energy Systems (2012-2014, with Okinawa Prefectural Government) to support basic technology research for energy in subtropical island areas.
