Our Business


Nippon Kayaku’s anti-cancer drug initiatives began with the launch of BLEO® and today we offer numerous pharmaceuticals. In recent years, we have expanded our initiatives to include biosimilar and generic anti-cancer drugs as well as interventional radiology (IVR). We also are focusing on developing new drugs based on the use of new technology.

We contribute to society through improved patient outcomes achieved as a result of innovation using our technological expertise, the stable supply of high-quality pharmaceuticals, and the provision of information. We undertake this commitment by posting dedicated cancer MRs in locations around the country. We also have established a drug information center (toll-free number available on our website), through which we respond to inquiries from medical professionals and provide answers to questions from patients and families of patients who have been prescribed Nippon Kayaku drugs by a medical institution or NHI network pharmacy.

Generic drugs

Nippon Kayaku is also engaged in the development of generic drugs. Since there are a large number of drugs involved in cancer treatment, including anti-cancer and anti-emetic drugs, in these generic drugs, the company has worked to further expand its lineup of cancer medications.

In 2010, IVR become Nippon Kayaku's third main pharmaceutical product area. The company's aim is to further enhance its lineup of embolic materials tailored to target organs, or the condition of the patient and disease.
