Meeting wide-ranging needs

Meeting wide-ranging needs

The health and product needs of consumers are diverse. Our company has continuously taken on various challenges to develop products that respond to people's voices and meet their needs.

For example, we have developed direct OTC medications such as the hair growth agent "Riap" and the visceral fat reduction drug "Alli," which were not previously prescribed by doctors in Japan. As Japan's first OTC medications, we have made them available for purchase at drugstores and other retail outlets.

We are committed to ensuring safety in all aspects.

Not only do we develop effective medications with minimal side effects, but we also maintain strict quality control from the procurement of raw materials to production and distribution. These rigorous standards are applied not only to pharmaceuticals but also to health foods, which we manufacture under stringent self-imposed criteria.

Since it is crucial to provide a continuous supply of medications, we implement proper inventory management during normal times and take measures to ensure uninterrupted delivery of products even during disasters.
