Since our founding in 1870, we have supported regional infrastructure and daily life, steadily building trust and a solid track record while responding to the needs of each era.
Starting as a fertilizer merchant, we walked alongside Japan’s modernization by supplying foundational resources such as coal, petroleum, and lubricants—a history deeply intertwined with the evolution of energy itself.

Today, our vision is to create a “next-generation infrastructure we can be proud to pass on.”
We continue to tackle global challenges—climate change, geopolitical risks, and the decarbonization of energy—by harnessing the power of innovation to pave the way toward a sustainable future.
We promote the adoption of renewable energy, the dissemination of energy-saving technologies, and solutions that underpin a circular economy.
By exploring sustainable energy usage tailored to diverse business environments, we advance value creation through a holistic approach that integrates society, economy, and environment.

At the same time, we aim to rediscover and share with the world the unique cultural and historical assets cultivated in our region, contributing to the diversification of industries and the independence of the local economy.

We believe that even the smallest step, starting from the local community, can shape a sustainable future that transcends generations.
We are committed to continuing our challenge to build a future worthy of the next hundred years.
