Group-wide Cooperation to Ensure Stable Supply of High-Quality Products
Core Principles
Production departments at the Otsuka group employ a traceability system covering all stages of the supply chain, from raw material procurement to production, distribution, and sales, thereby enabling thorough management throughout the entire supply chain.
Promotion System
The Chemistry, Manufacturing and Control* (CMC) Headquarters established in April 2022 by Otsuka Pharmaceutical’s Pharmaceutical Business Division, aims to deliver high-quality pharmaceutical products to patients faster by establishing an integrated R&D system for active pharmaceutical ingredients and formulations, thereby seamlessly promoting the process from pre-clinical studies to commercialization. In addition to supporting stable production and supply in terms of technology, we pursue the maximization of product value by making full use of CMC technology, including the addition of new dosage forms. The Otsuka Group also works to leverage its strengths through personnel exchange and training that transcends departmental boundaries, collaboration within the Otsuka group, and regular sharing of information on technology and other topics.

Held a Group-Wide Global Quality, Production, Supply Chain, and Environment Meeting

As our business grows and our products and sales areas expand, we hold an annual cross-group global conference to deepen mutual understanding and strengthen collaboration among the various departments of the value chain.
Under the theme of “Our value - Thinking at milestones,” 156 participants from 15 countries/regions shared their approaches and issues with each other regarding mechanisms to support stable supply, value creation for the future, and meeting new social needs.
During the conference, we also conducted an award ceremony to commend employees for outstanding initiatives in production activities.
Education system
At the Otsuka group, production departments formulate an annual education plan for each production site, provide training on health and safety and good manufacturing practices, as well as regular training on business continuity planning (BCP) and compliance.
Expert training systems
Otsuka Pharmaceutical’s Manufacturing Division initiated a new HR development program in 2021 with the aim of helping develop expert engineers and future managers who can respond globally.
Apart from technical training, we collaborate with in-house departments on management training and we cultivate individuals that can contribute on a global scale through factory training at both domestic and overseas sites.
Employee proposals for improvement
Every company in the Otsuka group works hard to make unique proposals for improvement. As an example, at Otsuka Pharmaceutical Factory, we have been continuously engaging in activities for many years that aim to enhance the awareness of creativity and ingenuity among employees. This is achieved by widely soliciting meaningful proposals from employees, adopting and implementing useful suggestions, and thereby promoting the development of the company along with the employees' innovative spirit. Similarly, Otsuka Chemical aims to create a comfortable workplace by ensuring safety and security. They solicit improvement measures from employees, share improvement cases, and hold an annual conference to recognize outstanding examples.
