About Us
Message from the CEO
Juzen Chemical was established in 1950 as a manufacturer of antihistamines and pharmacopoeia drugs, and then, entered the organic intermediates field in 1956 with the production of monochloroacetic acid.
After that, Juzen Chemical expanded the business field to contract manufacturing services for value added intermediates and APIs.
Today, in the global pharmaceutical companies, outsourcing has become a prevailing trend, and the pace of this trend seems to be accelerating.
Against this background, Juzen Chemical is aiming to be the best partner and CDMO for global pharmaceutical companies, which can provide services as one-stop service, covering all stages from research and development support and manufacturing of investigational drugs to stable supply of commercial products. To achieve this, we are now actively working on acquisition of new technologies and investing in equipment.
In 2015, we built a state-of-the-art GMP compliant plant, capable of multiple-APIs production. Owing to the completion of this plant, which is equipped with a wide range of GMP compliant equipment, our quality assurance system was enhanced from the hardware aspect, in addition to the existing software quality assurance.
Furthermore, based on the organic synthesis industrialization technologies we long nurtured, integrated service that covers all stages from development of new drugs to the commercial production has become available by using the small-scale production plant that complies with the investigational drugs GMP along with other plants.
In addition to the cost advantage of the multi-item production system, we will be able to offer more attractive prices by using the existing multi-purpose intermediate plants in a collaborative way.
In 2017, responding to the demand of the times, we launched CMC solution service business, leveraging our experience and expertise. We have assisted pharmaceutical companies in many activities, including development of manufacturing routes and analytical method test method development.
In 2024, we carried out the expansion of the GMP-compliant API plant, as well as increasing equipment for nucleic acid medicines, as we are taking on new modalities.
In the rapidly evolving global pharmaceutical industry, we, Juzen Chemical, are confident in our capability of meeting the diverse needs of our customers with our world-class technological expertise.

Vision2035
“In the new era of drug discovery (*), we aim to become the ultimate Monozukuri partner—trusted from early-stage development to commercial manufacturing—accelerating the delivery of better-matched medicines for each patient.”
* What We Mean by “The New Era of Drug Discovery”:
To meet the growing need to deliver medicines that are better suited to each individual patient, high-mix, low-volume production is becoming more common, more drug candidates are originating from startups, and technologies such as AI are dramatically accelerating the speed of drug discovery.
The Story Behind Our Vision
Advances in genetic analysis and the growing focus on rare disease treatments are driving a shift toward better-matched therapies—designed to address the specific needs of each patient more effectively.
As a result, pharmaceutical manufacturing is becoming more complex, with increasing demand for high-mix, low-volume production.
At the same time, rapid innovation in areas such as AI-driven drug discovery is dramatically shortening development timelines.
To fully realize the potential of these advancements—and to ensure that effective treatments reach patients quickly—strong Monozukuri capabilities that can support our customers’ drug development efforts are absolutely essential.
At Juzen Chemical, we are committed to transforming ourselves to meet the demands of this new era.
While building on the strengths we have cultivated over the years, we are making bold shifts to support high-mix, low-volume production, speed-oriented manufacturing, and capabilities that extend from the earliest stages of development through to commercial production.
Our goal is to become the ultimate Monozukuri partner—a company that can be entrusted with every stage of the development process, from beginning to end.
In doing so, we aim to help shape a better future for each and every patient through the power of Monozukuri.
Although this transformation may not be easy, we once undertook a major shift from fine chemicals to pharmaceuticals. That same spirit of challenge and reinvention lives on in our DNA.
With that drive, we will continue to strengthen our Monozukuri capabilities and take on the challenge of realizing this vision.
