Improving product quality

Improving the development & production process

In manufacturing, we believe it important to achieve greater quality in upstream business processes. We aim to not only raise the quality of the products and services we introduce to the market, but also that of the development and production process itself.
For our Group’s newly developed products, the Quality Assurance Division checks the design reviews that are performed at each step, from product planning to the production preparation stage, to ensure that reliable quality is designed in from the start.
At our Tire Technical Center, we are implementing robotic process automation (RPA) software that automatically processes routine tasks. Through this, we aim to see how it improves operational efficiency by preventing potential risks in the course of business, such as human errors and fraud.

Meeting the quality standards of each country

We are aiming to strengthen our own quality standards throughout the Group in order to fully comply with the increasingly complex quality-related laws in each country — such as environmental performance and quality legislation promoting vehicle fuel efficiency improvements and reduced CO₂ emissions, being rapidly introduced in the face of rising climate change risks. Once per year in each of our tire and automotive parts divisions, we hold global quality assurance meetings led by those in charge of quality assurance and other relevant employees at our production sites in and outside of Japan. These meetings are opportunities for each site to share and collectively discuss initiatives related to product quality and quality system improvements in production processes, and requests about quality from suppliers. The four sites for Group tire testing and evaluation in Japan received ISO/IEC17025 certification (general requirements for the competence of testing and calibration laboratories) for the first time in 2013, and have since been improving test accuracy and confidence to continuously conduct tests that conform to standard requirements.

ISO/IEC 17025

Example efforts to meet quality standards

  • Collecting information locally
  • Making recommendations by participating in industry groups
  • Exchanging opinions with regulatory institutions
  • Sharing information on the latest legal and regulatory trends
  • Giving presentations on legal and regulatory matters

Improving service quality at sales companies

Our tire sales companies are committed to ensuring that our customers – the consumers – can choose our products with confidence, peace of mind and satisfaction by training our staff to a high standard of customer service and improving the skills of our technicians.
For example, Toyo Tire Japan Co., Ltd. and independent distributors in Japan conduct job-specific training to foster talent that possesses the required level of service quality for their respective roles, such as sales and customer service. They also provide specialized training for sales associates in order to equip them with the awareness and skills required to communicate effectively with customers and explain accurately what value our products provide.
We also hold a Truck and Bus Tire Servicing Contest with the primary goal of improving the skills and service level of technicians who exchange tires and perform inspections and after service. Technicians selected from all over the country compete with each other to show their skills, and the activity also illustrates how their own jobs help both customers and society, fostering a sense of duty and motivation toward their work.

Increasing customer satisfaction

Maintaining and improving quality and satisfaction

As a manufacturer, we understand that our products and services link us to both customers and society, and devote ourselves each day to maintaining and improving product quality at our production sites. We are also conscious of improving the “quality of organizational citizenship behaviors” at all workplaces, and strive to provide products and services designed with a customer-centric approach.
We also conduct ongoing product satisfaction surveys in markets where each product is available, and relay customer requests as feedback to design and production sites.
For example, for more than 50 years, we have held Quality Control (QC) circle activities to proactively raise quality control standards using employee insight from the frontlines. QC circles began at production sites and have now spread to sales divisions, with about 300 total circles currently running within the Group. Members bring with them their experience and knowledge in order to resolve problems, and work to improve quality by understanding current conditions, setting goals, developing activity plans and analyzing issues.
Each year we run a company-wide QC circle event where circle representatives from around the world visit our head office to present local initiatives for improving quality control and eliminating waste and loss in the workplace, with the aim of achieving a global information and learning exchange. Just as in 2022, the 2023 event took place remotely with circle representatives from each base making online presentations that were assessed by a panel of judges. Moving forward, we will continue supporting QC circles to further improve worksite autonomy and customer satisfaction.

Responding to feedback from consumers

Every piece of feedback that we receive from our customers is valuable and provides us with opportunities to understand their expectations for the Group and improve our products and services. In 2023, our Customer Relations Department received a total of 2,611 inquiries in Japan. We respond to phone and online contact from customers both accurately and simply.
We analyze the content of these inquiries and send the findings to relevant departments to improve the usability of our products and services. Such efforts have led to the development of the Open Country series, our popular line of SUV tires, and the improvement of the readability of our catalogues and websites.
We take complaints seriously, and work with the Group's sales divisions and technical service departments to ensure that issues are dealt with promptly and satisfactorily, and that the problem or complaint is resolved so that we can build a long-lasting positive relationship with the customer.

Visualizing manufacturing quality using Manufacturing Execution Systems (MES)

Visualizing manufacturing process quality data to improve processes

Our Group aims to construct a quality assurance system where defects in manufacturing processes can be predicted and prevented before they happen. We are introducing automatic measuring equipment into tire manufacturing processes to create a system that can collect digital information from equipment related to quality and production, then visualize it. This makes it possible to assure quality for each individual manufacturing process, analyze collected data, and detect changing trends in processes through monitoring. The Manufacturing Execution System (MES), due to be implemented at our Serbia Factory in the second half of 2024, will also be expanded to cover quality management, and the results will be analyzed while the system is rolled out in stages to other production sites. At the same time, we are also working to promote wider use of data through human resource development as well as by developing a data-driven corporate culture.

[TOPIC] The new Serbia Factory

In December 2022, the Group opened its first passenger vehicle tire production plant in Europe.
Equipped with the latest technology, including enterprise resource planning (ERP) and MES, the Serbia Factory is a smart factory that visualizes production processes and links together highly productive equipment with incredible precision to unlock a higher dimension of production management system optimization.
In 2019, we established an R&D center in Germany where we continue to search for and research cutting-edge materials, collect the latest information on vehicles and markets, and advance the study of high-performance technology development in the structure, shape and pattern design processes.
Taking advantage of these cutting-edge technologies, the Serbia Factory will produce high-performance, competitive tires that meet market insights, including the shift to electric vehicles.
On the premises we have set up a solar power generation system (with a capacity of 8.4 MW), which will generate 10.15 GWh of electricity annually and help reduce 7,100 tons of CO₂ emissions.
As of January 2024, the Serbia Factory has acquired ISO 9001 (quality), ISO 14001 (environmental) and ISO 45001 (occupational health and safety) management system certifications. We will continue to manufacture products that satisfy more customers, with the aim of delivering market competitiveness.

Creating an RFID system to ensure traceability

In May 2022, the Global Data Service Organization for Tires and Automotive Components (GDSO) was established as an international non-profit organization working to standardize and share tire data in the industry. We are developing the technology and production facility to equip tires with radio frequency identifier (RFID) tags, and exploring how the data acquired through the technology can be used.

Promoting improved awareness of tire safety

As a tire manufacturing and sales company, we at the Toyo Tire Group see it as our duty to educate customers on the importance of regular tire inspections for improving safety. Each year we run tire safety awareness events.

[TOPIC] Tire safety awareness activities in 2023

We believe that it is a duty of our Group as a manufacturer and a company committed to mobility to raise drivers’ awareness of the need for regular tire inspections to ensure their safety. We run campaigns to raise awareness of tire safety, highlighting the need for regular tire inspections, giving tips for driving in rain and promoting other safety-conscious practices.
In order to help drivers to understand the importance of maintaining tires in good condition, we have been running tire safety awareness campaign events across Japan since 2019 using a driving simulator with our proprietary software. In 2023, we held events during the spring and autumn National Road Safety Campaigns in cooperation with the local police forces. Over the four years, a total of around 3,200 people took part in these events, with 98% of respondents to post-event surveys saying that the experience helped to raise their awareness of tire safety.
The driving simulator provides a realistic driving experience by recreating views from the driver’s seat as well as road noise and vibrations, which are all synched to inputs through the steering wheel and the accelerator and brake pedals, so that participants can experience how driving around a corner in rain feels when tires are worn, what the difference in braking distance is between tires with sufficient tread and those with worn tread, and what happens when a tire blowout occurs while driving. By giving drivers opportunities to experience these unfamiliar situations through simulation, we try to make them aware of the importance of keeping tires in optimal conditions.
We will continue using our driving simulator to further boost interest in tires and help make drivers aware of how to use them properly.
