SB Energy sets its core business in three categories: the Watts Business that generates power using natural energy; the Bits Business that combines renewable energy with AI and IoT to build energy platforms;and the Mobility Business that combines renewable energy with battery cells of electric vehicles (EVs) etc. to develop services. Based on these three categories, we expand our business domains and help spread the use of renewable energy.

Through the Golden Triangle of the Bits, Watts, and Mobility Businesses, we build energy platforms in Japan and the world. We also build new business models to cope with massive industrial structure changes, being prompted as renewable energy is now redefining industries.


For the realization
of a prosperous society
that we can be proudly
passed on to our children

On 11th of March 2011, the Fukushima Daiichi Nuclear Power Plant accident was induced by the Great East Japan Earthquake. The myth of absolute safety crumbled and we were confronted with the need to seriously consider energy issues for our future.
In order to resolve these challenges in the 100 or 200 years term, a reliable, safe and sustainable new energy source is required. Renewable energy can resolve the problems and expectations grow for photovoltaic and wind power generation.
For the realization of a rich society that we can be proudly passed on to our children we are actively promoting the spread of renewable energy.

Toward a new era
where the renewable energy
redefines all industries

The historical Paris Agreement has spurred the use of renewable energy around the globe, making it a choice for its economic rationality, rather than purely from environmental perspectives.
Since the 1st Industrial Revolution, history has always revolved around the paradigm shifts on communication, energy and transportation. Now the rise of AI and evolution of technology is redefining the game structures of all the industries. Against these backdrops, SB Energy sets its business cores in the Bits, Watts, and Mobility – aiming to create an energy platform that is reliable, safe and persistently available. That is the platform that underpins our Softbank Group’s Information Revolution pursued since its foundation. Through these approaches SB Energy will strive upon to expand the use of renewable energy in Japan and the world.
