Safety and Reliability

The Nisshin Seifun Group is dedicated to supplying consumers
with dependable products that contribute to good health.
As a food manufacturer, we recognize quality assurance as our most important responsibility.

The guiding philosophy of the Nisshin Seifun Group since its founding in 1900 has been that “the basis of business is built on trust,” and that a business needs to be “in tune with the changing business climate.” Our corporate principle has been to “contribute to a healthy and fruitful life for all.”

One of the principles in our Corporate Code of Conduct and Employee Action Guidelines, which we adopted in 2002, is to “develop and provide reliable, safe, and high-quality products and services. This principle requires us to comply with related laws and regulations, and to build and maintain quality assurance systems that give first priority to quality assurance from the viewpoint of consumers.


The Quality Assurance Policy of the Nisshin Seifun Group

Every Nisshin Seifun Group employee practices quality assurance from the viewpoint of consumers,
asking themselves whether they could clearly explain the work they are doing to the consumer.

  1. The Nisshin Seifun Group defines quality assurance as accountability to consumers about the safety and reliability of every aspect at every stage of our business, including manufacturing.
  2. We create structures to ensure regulatory compliance and product safety at every stage of the supply chains that deliver our products to consumers, from safety assurance for raw materials, to development, production, marketing, distribution, and storage.
  3. We will consistently implement quality assurance from the viewpoint of consumers in line with our commitment to reliably supplying supply safe, high-quality products.
  4. We will continually enhance the Group’s quality assurance systems by obtaining and administering certification under international management system standards.

Quality Assurance Systems in the Nisshin Seifun Group


Independent Quality Assurance Systems

All quality assurance tasks have been integrated under quality assurance units that operate independently from production units. This has resulted in a more effective and organized approach to quality assurance.

Establishment of Quality Assurance Units

The parent company and business companies in the Nisshin Seifun Group have established quality assurance units that operate independently from production units. The parent company’s quality assurance units implement group-wide quality assurance activities under the direction of the Quality Assurance Director. The Quality Assurance Director also oversees the activities of Quality assurance units in business companies, which formulate quality assurance activity policies and provide guidance and supervision in factories.

By operating independently from production units, the quality assurance units can consistently prioritize quality assurance from the viewpoint of consumers.

Quality Assurance Controller system

The Nisshin Seifun Group’s core philosophy on quality assurance is that in order to create safe products that consumers can enjoy with confidence, we need to ensure quality from the viewpoint of consumers. We have put this philosophy into practice by appointing Quality Assurance Controllers in the head offices of business companies and at manufacturing facilities to implement quality assurance activities independently from production units.

Quality Assurance Controllers (QAs)

Quality Assurance Controllers are responsible for decision-making, reporting, and educational activities.

  • The decision-making role of Quality Assurance Controllers involves determining whether products shipped from each factory meet the required quality standards from the viewpoint of consumers, as people who consider themselves accountable to consumers. They also check the appropriateness of all actions at every stage from production through to storage and distribution.
  • Quality Assurance Controllers report their decisions directly to factory general managers and the General Manager of the Quality Assurance Division.
  • In their educational role, Quality Assurance Controllers run educational programs designed to maintain and improve the level of quality assurance systems.

Tsuneo HironakaNisshin Flour Milling Inc. Fukuoka Plant

The educational activities I carry out at the plant include monthly workplace meetings in which we hold “hazard prediction training (Quality Kiken Yochi).” This involves looking at recent cases experienced at both our sites and other companies and then considering the causes and countermeasures. This enhances the awareness of employees regarding food safety by having each of them think about cases and then share their opinion. I plan to further develop and enhance our activities going forward by holding this training online. This has the advantage of being more accessible to employees by enabling them to participate at whatever time is convenient and by implementing this in tandem with conventional sessions at workplace meetings, I hope to generate synergistic effects.


Kazue NamikiOriental Yeast Co., Ltd. Tokyo Plant

As a Quality Assurance Controller, my role is to inspect all the processes at the plant from the standpoint of whether I can explain things accurately to the consumer. Also, as part of our educational activities, I offer my realizations through work-site observation to workers on site, about things that I think are good or that make me uneasy. Through this communication, I’m encouraging the building of a consumer-orientated quality assurance culture among employees on the site and receiving frank feedback from workers, such as whether current work rules are reasonable for them. My goal is to maintain a quality assurance structure based on two-way communication, rather than top-down rules.


Makoto OnodaNisshin Seifun Premix Inc. Nagoya Plant

When approaching my work as a Quality Assurance Controller, I always try to get an accurate understanding of each situation by gathering information based on the “Three Reals Philosophy (Sangen Shugi),” which involves going to the actual place and seeing the actual part and the actual situation. I then make assessments based on this situational understanding, starting by considering whether I can truly explain to the consumers that our products are safe and whether they will accept my explanation. In this way, I strive to ensure that consumers receive better and more reliable products. I report the results of my assessments to the plant manager and the general manager of Quality Assurance Department at headquarters in an accurate and timely manner to facilitate the sharing of correct information throughout the company, checking my decision for any mistakes.


Asako ShinboriTokatsu Foods Co., Ltd. Yokohama Tsurumi Factory

The Yokohama Tsurumi Factory produces salads and other prepared foods for convenience stores in two shipments a day. As deliveries are made on a daily basis, there is not much time for me to make product release decisions and to report the results to Quality Assurance Controller of headquarter. It’s like a race against time. When carrying out inspections and approving shipments, our top priority is that we can explain to consumers that our products are safe. As many of our employees are from countries other than Japan, we prepare notices and videos of production processes and rules in multiple languages to improve food safety. We try to create these tools in a way that conveys the information visually in an easy-to-understand manner, and we strive to improve food safety through education.


Atsushi OkadaNisshin Seifun Turkey Makarna Ve Gida Sanayi Ve Ticaret A.S.

Turkey is the world’s third biggest producer of durum wheat. Our plant uses this high-quality wheat to produce Ma•Ma Spaghetti, a long-time bestselling product for the Group, which is exported to Japan. We use the same production management and quality assurance structures as our plants in Japan to ensure the production of high-quality products. My top priority personally is communication with my Turkish colleagues. I share with them feedback from Japanese consumers to help them understand the level of quality that is expected in Japan. I believe this effort is very effective for enhancing continuous improvement activities at the plant little by little. A lot of Turkish people are Japanophiles, so this provides daily encouragement to create even safer and more reliable products.

Today’s customers and consumers expect food that doesn’t just meet government regulations, they expect food to be safe, reliable, and nutritious. Producing foods that meet these expectations is a foundation of the Nisshin Seifun Group. Our commitment to quality and food safety encompasses the entire product life cycle – from product design and development, through the production process and extending to the delivery of products and services to the customer. All processes and management systems are monitored, measured, and reviewed to continually improve product quality and ensure customer satisfaction and confidence. The basis of our business is built on trust. Food safety, quality and reliability are key components of building trust with our customers and consumers.


Safety Assessment and Screening of Raw Materials, Products, and Premiums, etc.

Highly qualified staff in business companies in the Nisshin Seifun Group conduct safety reviews of new and existing raw materials, products, premiums, and other items. Safety screening is also carried out at the parent company’s Quality Examination (QE) Center.

Safety review

Before selecting new raw materials, products, premiums, or other items, business companies in the Nisshin Seifun Group conduct safety reviews covering regulatory compliance, hazards, universal design compliance, environmental soundness, labeling, and various other criteria. These reviews are conducted by staff with advanced technical knowledge. Only items that pass will be accepted for use.

Products that are already on the market are also subject to ongoing safety reviews to ensure that there are no environmental issues or problems with the raw materials or production processes used, and to check compliance with the safety standards established at the design stage.

QE Center

The task of the QE Center is to conduct checks based on scientific criteria to confirm the safety of all new raw materials, products, premiums, and other items approved through safety reviews conducted by business companies. QE Center Staff use advanced equipment to conduct a wide range of analyses, including tests to detect residual pesticides, food additives, food poisoning bacteria, allergens, genetic material, radioactive substances, and contaminants. Final decisions on whether or not to use or sell each item are based on the results of these analyses. The QE Center was the first unit of a Japanese food manufacturer to obtain ISO17025 certification for pesticide analysis. Since then, it has also obtained certification for microbial testing and radioactivity measurement, enabling it to conduct high-precision analyses as one of the few organizations in the industry with expertise in this area.

Checking Raw Materials

Raw materials undergo safety checks before their selection for use in our products, and after procurement. Pre-selection checks involve the following three steps.

  1. Before the safety review, development and safety management staff visit the raw material supplier to check that the product complies with the standards.
  2. Samples of the product are extracted for safety analyses.
  3. A standard document or warranty is obtained from the supplier to certify that the raw material supplied meets the standards.

After we start to procure a new raw material, we continue to check its safety through sampling tests based on a yearly schedule. Depending on the attributes and risk factors of each raw material, we carry out the following tests.

  • Residual pesticide analyses
    We obtain samples for each item and production area at the start of the harvest period. We determine which pesticide tests to implement based on the pesticides used, test results from quarantine stations, and records of previous violations.
  • Allergen analyses
    To protect food allergy sufferers from adverse health consequences, we conduct analyses for specific raw materials for which there are labeling requirements.
  • Food additive analyses
    We decide which additives to test for according to records of previous violations and other data. We take particular care to test for additives that are permitted overseas but prohibited or restricted in Japan.

We also conduct additional safety checks, including microbial and contaminant testing and analyses to detect mold and heavy metals.

Labeling Checks

Our product labels clearly state safety and quality information, including ingredients and “best before” dates. We thoroughly check the content of our labels, both to ensure compliance with Japan’s Food Labeling Act and Act against Unjustifiable Premiums and Misleading Representations, and also to avoid wording that could be misunderstood by consumers.

In addition to checks during safety review meetings at individual business companies, the group parent company’s Customer Service Office, Legal Division, Intellectual Property Division, and Quality Assurance Division also verify the appropriateness of label content from their various perspectives and provide feedback to business companies.

Also, during Quality Month (November), we hold workshops on food labelling for the personnel responsible for labelling at each Group company to raise awareness and provide them with the knowledge needed to practice appropriate labelling.


Ensuring Traceability

We ensure traceability by maintaining records at each stage from the acceptance of raw materials through to manufacturing, storage, and logistics.


We record data relating to the raw materials used and manufacturing, storage, logistics, and other processes as the basis for traceability. This approach allows us to check data reliability quickly and effectively by tracing back from finished products to raw materials, and forward from raw materials to finished products. In the unlikely event of a problem, we can immediately identify the cause and initiate a product recall.


Food Defense

We have established the Nisshin Seifun Group Food Defense Guidelines as a precaution against deliberate attempts to contaminate our products. These guidelines are the basis for a consistent group-wide approach to product security.

Food Defense Guidelines

Under the basic policy outlined below, we have established security standards for employees, production areas, sites, buildings, and storage facilities.
(1) We will endeavor to create pleasant working environments for our employees while raising their security awareness through education and training.
(2) We will strengthen access controls to allow monitoring and tracing of personnel at sites, in buildings, and in production areas.
(3) We will install cameras where required to enhance our capacity to prevent deliberate attempts to contaminate our products, and to support tracing.
We will regularly conduct self-inspections to ensure that operations are being managed according to these guidelines.
We will update the guidelines as required in response to changes in the social environment.

Quality Assurance Training

We provide quality assurance training for all employees with the aim of raising employee awareness of product safety. Through this training, we help employees to develop and consolidate their understanding of quality assurance from the viewpoint of consumers.

Training for All Employees

Employee awareness of quality assurance is essential to food safety. We enhance that awareness by providing quality assurance training each year for all officers and employees working in R&D, production, and sales at our business companies in Japan and overseas. This training covers a wide range of food safety knowledge, including general hygiene management, the standards and rules of the Nisshin Seifun Group, changes in industry and government standards, and related regulations Yearly training for Quality Assurance Controllers also includes food safety lectures presented by outside instructors.

Nisshin Quality Assurance Audits, Manufacturing Environment Monitoring

All manufacturing and storage facilities undergo Nisshin Quality Assurance Audits (NQ Audits) as part of our commitment to maintaining and improving quality assurance. We also monitor the status of hygiene control processes in our manufacturing environments.

Nisshin Quality Assurance Audits (NQ Audits)

The auditors appointed by Quality Assurance Director conduct quality assurance audits of all head offices and manufacturing and storage facilities of Group companies using the NQ Audit checklist developed by the Nisshin Seifun Group. Aspects covered in the checklist include requirements under food safety management standards and related laws and regulations (Food Sanitation Act, Food Labeling Act, and Act against Unjustifiable Premiums and Misleading Representations), as well as case studies of problems at group facilities in Japan and overseas, and the viewpoint of consumers.
The purpose of the audits is to identify not only existing problems, but also potential causes of future problems, leading to the early discovery and rectification of risk factors.

Manufacturing Environment Monitoring

The QE Center uses scientific data to check the status of hygiene management systems in the factories where the Nisshin Seifun Group’s products are manufactured. Monitoring includes microbial testing through checks for falling bacteria, swab tests, and product sampling. ATP tests are used to check the standard of production line cleaning, while chemical tests are carried out to detect contaminants. Monitoring results are fed back to business companies for use in maintaining and enhancing their manufacturing environments.

Third-party Inspections

We employ independent external inspection organizations to check the appropriateness of our quality assurance audits (NQ audits) by examining product safety measures in our factories.


Responding to Significant Quality Incidents

Employees report any significant quality incidents to top management without delay. Top management immediately establishes a task force to take appropriate and timely action.

Call Center Reporting System

In the event of an emergency situation that could impact on the business operations of the Nisshin Seifun Group, such as a fire, natural disaster, or accident, or an abnormal situation that could be reported publicly, employees must first contact the Call Center to make an initial report about the situation. Reporting is required not only through the Call Center but also via the corporate administration system. In the case of situations affecting product quality and safety, reports must also be submitted through a third route based on the quality assurance organization.

Significant Quality Incident Task Force

When a problem is reported, top management will consider the situation and decide whether or not to establish a task force. In the case of a serious issue relating to product safety and quality, a Significant Quality Incident Task Force will be established and will immediately begin to ascertain details, decide whether to recall products, investigate the causes, and implement recurrence prevention measures.


Using Customer Feedback

Product feedback or requests submitted to the Customer Service Office by consumers are reviewed by staff in related areas, such as quality assurance, development, and production, and used in product improvement and the development of new products.

Customer Service Office

As part of its commitment to customer satisfaction and trust, the Nisshin Seifun Group established the Customer Service Office as a contact point for consumer inquiries and feedback about home-use products.

Each year the Customer Service Office receives around 12,000 calls from consumers. This input is shared with related units in areas ranging from R&D to production and sales through the CHORUS response system. In addition to providing a timely response to customer needs, these units also use this feedback to develop products from a consumer’s perspective. FAQ dialogues are also provided on the Nisshin Seifun Welna website in categories based on products and the purposes for which they are used.

Linking Consumer Feedback to Product Improvements

When customer feedback is received, the units concerned check the actual products and continually monitor the situation, including reviews of completed cases.
The Quality Assurance Director convenes Customer Feedback Review Meetings with staff from the Corporate Communications Division, Customer Service Office, Quality Assurance Division, and production units to review the number and details of cases over the previous week and study at investigation reports. Any cases that resulted in customer dissatisfaction are checked and shared at the Customer Feedback Review Meeting.
Consumer feedback and opinions about products that are already on the market are also reviewed at monthly Quality Improvement Meetings attended by staff from quality management, quality assurance, production, and production development units. This valuable information is used to improve products and services.
By knowing our customers and sharing information, we are able to fulfill our commitment to providing timely and sincere responses to all customer feedback.

Establishment of Consumer Relations (CR) Office

On October 1, 2009, we established the Consumer Relations (CR) Office under the direct control of top management. Its role is to gather accurate information about consumer attitudes and social trends, and to provide timely advice about systems and actions that we need to implement as a group. The CR Office also monitors consumer policy, gathers information from the Consumer Affairs Agency and consumer organizations, and shares the information with our group companies.
As part of its consumer communication activities, the CR Office sends staff to present classes at elementary and junior high schools and stages exhibits at consumer events run by government agencies. It also organizes factory tours for consumer groups and other organizations.
Because of the wide range of products that we bring to market, the Nisshin Seifun Group interacts with many related government agencies and organizations. To ensure an integrated response as a group, our parent company and individual group companies have CR officers who report directly to top management.


Using International Management Systems

We are continually enhancing and strengthening our product safety systems by acquiring and maintaining certification under international management systems.

Using Food Safety Management Systems and Quality Management Systems

We are preparing for global business expansion by continually strengthening our quality assurance structures under international management systems. By achieving and maintaining certification under various systems, including the ISO9001 quality management system, the ISO22000, FSSC22000 and JFS-C food safety management systems, and the ISO13485 quality management system for medical devices, we are continually improving our product safety systems.
