​Message  from Koichi Sato, CEO

August 2019, at Nadièye Satouré clinic

12 years ago, I started an IT consulting company in France and learned through involvement in ICT installation mission in French speaking regions in Africa, that there are lack of grid power in local villages and 600millions of African are living without electricity.


 As a Japanese engineer who has business experience in French speaking regions, I felt there must be something I could do. 


In April 2018, I made a commitment to myself to promote co-creation project with government organization that would promote sustainability in Africa.  I first launched a company in Tokyo and then decided to expand our project into Africa with a public-private partnership. 


Product demonstrations have already begun at health posts in un-electrified villages, and we have received positive feedback from local residents who have now an access to electricity and Internet. 


The TUMIQUI Project is more than just an equipment supply project, it is a project that involve local workshops/plants to make [Made in Africa] products, employ graduates of local technical schools, and in the future, lead to independent and sustainable growth through technology transfer, and eventually authority transfer from the headquarters. 


In the future, we aim to promote the development of neighboring countries outside of Senegal in order to contribute to create a better environment in health sectors, educational and agricultural fields and so on.


There is an African proverb that says, "If you want to go fast, go alone; if you want to go far, go together." Our style is, "The faster we go together, the farther we can reach. 


Businesses that make a big impact need people you can trust.  I would like to move forward on this path by sharing my vision and creating a community with the mutual passion with Japanese and African trusted companion.


Koichi Sato, President of SUCRECUBE Japon

Electricity and Internet across the vast lands of Africa.

The TUMIQUI Project's journey began with an encounter with Africa. Encountering Africa, that is to say, confronting many social challenges. The lack of electricity and internet is especially pronounced in Africa.  There are many areas without electricity, and even in urban areas, power outages are frequent.  For example, it is usual that electricity and water go out for two or three days.


When I visited clinics in un-electrified villages in Uganda and Senegal with JICA study tour, I heard that doctors had to hold a cell phone or a lamp in their mouth during childbirth in the dark because there is no electricity, and of course many lives are lost.  I felt strongly that some lives could be saved if they are equipped with proper electricity.

Therefore, we decided to first focus on the health field supporting UHC (Universal Health Coverage) and establish our business entity in the Republic of Senegal.   We will expand our business then to West Africa.

Recognizing the need for public-private partnerships in order to solve social issues efficiently, one of the first things we started when we established SUCRECUBE Japan to promote this project in April 2018, was to begin collaborating with domestic and international government agencies, ministries and international organizations such as UNIDO (United Nations Industrial Development Organization) and JICA (Japan International Cooperation Agency) .

After two months of negotiations with the Senegalese Ministry of Health, we managed to sign a memorandum of understanding (MOU) to conduct trials of our equipment in health posts.  We were also successful in gaining a confidence of our business partner in Côte d'Ivoire and signed a MOU to promote business locally. 


 In January 2020, we also signed a MOU with the city of Sandiara thanks to the coordination of UNIDO, and became the first Japanese company to participate in a smart city project in Senegal.

Issues solving of the SDGs with electricity and Internet


Let's consider electricity and Internet, using mobile phone data as an example.

Africa has 456 million mobile subscriptions in sub-Saharan Africa in 2018. It is said to exceed 600 million by 2025, and about 50 percent of all sub-Saharan Africans will have a mobile phone. (From GSMA)

However, only less than a half of the people who have a mobile phone have an access to the Internet.  The reason is that the infrastructure is still inadequate in many ways, such as weak communication, or lack of money on prepaid phone (even if they have a mobile phone), or the distance they have to make to recharge their telephone batteries. 

Today, the internet is an infrastructure as important as the pavement of the road in developed countries.  They use cell phones for mobile money via SMS, they all love to take photos and selfies, exchange messages using application such as WhatsApp (equivalent to LINE or messenger), and enjoy social networking services such as Facebook… the interests are the same in Africa!  If the electricity and Internet are more available, they are able to exchange with their families and friends living far away from one another.  

If we can supply equipment that generate electricity with solar power, we can, not only charge mobile phones, but also other devices such as PCs in educational fields, medical devices in health posts, Fintechs for efficient agriculture operation. 

TUMIQUI equipment providing battery and solar power will deliver electricity and Internet to unelectrified villages in Africa and become local ICT plat-formers while solving issues of the SDGs.

TUMIQUI philosophy

Our goal of sustainable business is linked to the development of Africa. In this context, sustainable business means not only delivering goods, but also increasing local employment and help them lay the foundation of their own business so that each country can be more independent.

Now that a certain level of economy is reached worldwide, it is important for each society to take social actions considering the balance of the worlds’needs and contribute to each issue facing us.

We would like to create as many happy businesses as possible where people of different races can deepen their understanding of each other and find motivation and fulfillment in their work by contributing on issue solving.

TUMIQUI's philosophy is to find a right solution in West Africa and accumulate various ideas and technologies based on electricity and communications.
