We will support lives of people through supply of Iodine, which is Japan's world-class natural resource.

Thank you for accessing our website.

On January 1, 2022, K&O Iodine Co., Ltd. (formerly known as Nihon Tennen Gas Co., Ltd.) made a fresh start as a manufacturer of iodine and iodine compounds, following an integration of iodine businesses in K&O Energy Group Inc.

Iodine, the core of our business, is precious natural resource that Japan produces about 30% of the world production. Iodine, essential element to life, has wide range of application such as X-ray contrast media, disinfectants, polarizing film, etc., and its market is steadily growing. Through the business integration, we have become an iodine manufacturer that accounts for about 5% of the world production. We will continue to grow together with the market expansion.

As a company that handles natural resources, we will engage in sustainable and environmentally friendly operations to contribute to the healthy and comfortable society together with local communities.

We look forward to your continuous support and cooperation.
