We are a lubricant oil planning and marketing company.
I engaged in lubricant oil business at Sanwa Kasei Kogyo Co., Ltd. for 33 years., 10 years in quality control,
development and 23 years in marketing from 1985 until December 2018.
Then, I established Jyunken Co., Ltd. in January 2019.
We provide you with lubricant technology, product planning and sales know-how utilizing my experience.

For OEM, we can cope with various requests ranging from standard to specialty lubricants.
If you are not satisfied with the existing products and want to intensify specific aspects of performance, or develop
new oil that is not available in the marketplace, it is possible that you manufacture your own original product.
We can provide comprehensive knowledge from containers, product design to packaging so that you can limit your burdens to the minimum level.
With collaboration with manufacturers we deal with, we can arrange manufacturing of various grades of lubricant and grease by selecting makers that can match your requirement.
It is possible that we supply equal quality of product with one time production from a small lot of 20L up to 10KL per batch.

We promise you supplying constantly stable and high performance products with each maker maintaining high level of quality management.

Please contact us for any inquiry regarding lubricant oil.
