Flowood, Miss. – On January 13, 2026, Ergon formalized a transformer agreement with Japan Sun Oil (JSO). Under this agreement, JSO is granted the rights to market, sell and distribute Ergon transformer oil products in Japan.
“It’s the natural next step,” said Chin Chin Wei, Regional Product Manager of Ergon Oil (Singapore). “We’ve worked with JSO for a while now, but with this kind of formal agreement, we can truly move things forward to invest more time, more money and more human capital into developing our transformer oil market. So, it’s a big step for us both.”
Ergon’s partnership with JSO has spanned more than 30 years, with the two companies working together to supply and transport transformer oil throughout Japan for customers in the electric power and industrial sectors.
“Over the past several years, many individuals from both companies have devoted considerable effort and worked hard toward the execution of this agreement,” said Yasuhide Iguchi, President and CEO of JSO. “We are getting into a new stage of the long history of our two companies. Looking back, the relationship between Ergon and JSO started in 1992, when JSO began taking Ergon’s naphthenic base oils.”
“Since then, using Ergon’s naphthenic base oils, our company has supplied high-quality lubricants not only in Japan but throughout the Asia-Pacific Region,” said Iguichi. “With the signing of the Distribution Agreement now completed, we will put forth further efforts to enhance the sales of Ergon’s world-leading transformer oils — HyVolt and OmniVolt — in Japan. I strongly believe this will further strengthen the relationship between the two companies.”
The Ergon family of companies is committed to our mission of meeting needs, supporting families and serving customers with high-value solutions worldwide in industries essential to global manufacturing and infrastructure.
