Environmental Approach

Working closely with its business partners, the Tsubaki Group aims to contribute to overall social and economic development through our business operations by supplying products that satisfy customers and provide the best value.

Basic policy

As we proclaim in our mission statement's Standards of Conduct, we will contribute to overall social and economic development by manufacturing products that satisfy customers, and will build open business relationships through fairness and honesty with our business partners, aiming for mutual prosperity and growth.
To achieve these objectives, we will promote quality management and productivity improvement activities in each business division, and enhance coordination with our business partners to build equal partnerships. In addition, we will work to ensure that we can meet expectations regarding quality, price, and delivery time.

Quality management

The Tsubaki Group has adopted zero quality defects as a companywide quality policy, and conducts a variety of activities aimed at achieving this goal.
In addition to sharing issues among business segments via monthly meetings of the Group Quality Committee, which is headed by the president and acts as the group's umbrella organization for quality management, each plant has built a quality management system based on the ISO 9001 standard and is working to further improve quality and productivity through the operation and continual improvement of this system.

Automotive Parts Operations initiatives

In Automotive Parts Operations, we have constructed a production and supply system with our Saitama Plant in Japan as the mother plant for facilities in the seven countries where the Tsubaki Group manufactures timing chain drive systems for automobile engines. In 2008, under the guidance of the Toyota Motor Corporation, we launched our "dantotsu improvement activities" aimed at achieving zero quality defects. In 2011, we pushed for further productivity improvements, shortening of lead times, and inventory reductions with the start of our "manufacturing reform activities." These activities led to big productivity gains at a new assembly wing completed in April 2013.
These activities also proved useful for fostering young technicians and transmitting skills from one generation to the next. With the success of this initiative, we have rolled it out in overseas group companies and among Japanese suppliers. It is contributing to our global competitiveness in the automobile parts business.

Manufacturing reform activities

Chain Operations initiatives

The Kyotanabe Plant, which is taking the
initiative in production reforms

In Chain Operations, Tsubaki is continuing efforts to put its manufacturing philosophy into practice overseas towards the maintenance and development of our global production system.
As the mother plant for industrial chain, the Kyotanabe Plant actively organizes exchanges with group factories overseas, and promotes the sharing of accumulated technologies, technical skills, and knowhow. In fiscal 2013, we welcomed group leaders from the new Tianjin Plant in China for practical on-site training, and quality and safety training.
In fiscal 2014, we began implementing new reforms aimed at constructing compact, flexible production lines capable of variable-lot/multi-model output with shorter delivery times.

Relationships of trust with business partners

The Tsubaki Group's high quality manufacturing is supported by the continual efforts of our suppliers. Having set a basic procurement policy aimed at creating long-term relationships of trust, in addition to sharing and learning together with suppliers, Tsubaki conducts a variety of group productivity improvement initiatives, including the guaranteeing of open entry opportunities, the pursuit of mutual development through fair transactions, and the proactive evaluation of new technology proposals.
In Japan 170 of our suppliers are members of the Tsubaki Business Partners Club. While encouraging friendship between member firms, the association deepens understanding with Tsubaki through a variety of events including general meetings and regular informal discussions.
