-------------【About the company】-------------
The company is a startup that operates the largest energy marketplace in Japan. Covering everything from electricity and fuel to environmental value, its goal is to achieve "Social Good" through a fair market that enables anyone to exchange all types of energy value in an open and accessible way.
As global energy conditions become increasingly uncertain, resource-scarce Japan is directly affected. For example, electricity prices—critical to the foundation of economic activity—have experienced extreme volatility. The energy marketplace developed by enechain empowers businesses to manage this uncertainty, contributing to the stabilization of the Japanese economy and revitalizing Japanese enterprises.
In order to mitigate the escalating risks of climate change, a global commitment to carbon neutrality is essential. The company’s environmental marketplace promotes decarbonization efforts across entire supply chains through the trading of environmental value. By accelerating the realization of carbon neutrality, it aims to create a brighter, more prosperous future for the next generation.
Through the power of markets, the company strives to enrich Japan’s economy and create a more sustainable society. By establishing a strong foundation in the form of an energy marketplace—an essential part of daily life—it brings lasting value and vitality to society as a whole.
