Message from the General Manager

Takehisa Morimoto

Yokohama Rubber has established “Deal fairly with society and value harmony with the environment” as its basic environmental policy, and it aims to be “a company having world-class strengths in technologies for protecting the environment.” Our Mie Plant is located in Ise City: the divine capital located along the Miya River, Japan’s purest river. In doing business in this region, we have a strong desire to protect the abundance of nature that surrounds us.

Since our plant’s acquisition of ISO 14001 certification in 1998, we have addressed environmental preservation through the full participation of our employees, such activities being centered upon our environmental management systems. Concerning preservation of the environment, we have conducted ongoing improvements due to the establishment each year of objectives for reducing environmental burdens. Special activities that we can be particularly proud of include the operational improvements and reductions with respect to resource usage amounts achieved by the “Waste Elimination Force,” a group mainly comprised of female employees, and the efforts of the “Frontline Support Team,” who have helped to transform support so that we can view manufacturing sites through the eyes of the customer. Furthermore, through the activities of the “Forever Forest Project” and “Kigyo no Mori (the forests created by companies)” initiatives, we have been creating forests and ensuring the conservation of water sources, such factors being valuable in the reduction of CO2, disaster-prevention and the protection of living creatures. The total number of trees planted thus far reached 30,179 with the 11th planting of seedlings in fiscal 2018.

With respect to the biodiversity protection activities commenced in 2012, we have successfully edited the illustrated books of natural life and plants that were created by each team; and we continue to implement our activities in an atmosphere that is both positive and enjoyable.

In January 2016, an agreement for environmental education collaboration was signed between Yokohama Rubber’s Mie Plant and Ise City Government. In addition to the existing visits to elementary schools to give courses on biodiversity, we have also implemented Mie Plant tours, tree-planting experience activities and biodiversity protection activities for four elementary schools in Ise City and engaged with three-party cooperation in the Electric Bus Riding Experience and Low Carbon Society Creation Course by Mie Kotsu. With the aim of working together to help safeguard the Ise region’s rich natural environment, we at the Mie Plant will cooperate to further promote environmental education within Ise City.

Immediately after the Great East Japan Earthquake of 2011, volunteers from the Mie Plant delivered emergency supplies to the township of Onagawa in the Oshika district of Miyagi Prefecture. Since then, Mie Plant employees have continued to provide support for the recovery of the Onagawa area. In April 2018, at the invitation of Onagawa municipal government, Mie Plant staff worked together with local people to install play equipment made from tires at two municipal day-care centers in Onagawa.

Furthermore, as a volunteer activity we conduct within our own region, we clean around our plant and support people who suffered damage from typhoon in conjunction with the municipal government and the local residents’ association.

This is an activity in which all Mie Plant staff members take part.

With the aim of maintaining our status as a plant that is loved and trusted by people in the region, in the future we will continue to undertake a range of activities.

Organizational Governance

Thorough compliance policies

All Mie Plant employees are issued with “compliance cards” and are familiarized with the Yokohama Rubber Group compliance guidelines, and with the availability of contact points for discussing compliance-related issues.
A Compliance Committee is held, and hierarchical education is conducted.

Organizational self-corrective functions

We established a suggestions box in the plant’s cafeteria, enabling us to receive feedback from employees. In addition, the Mie branch of the labor union has established its own online consultation window for employees. Paying great attention to the views and wishes expressed through these channels, and working together with the Mie branch of the labor union, we are continuing to implement measures aimed at strengthening the sound operation of the organization.

Human Rights

Education on respect for human rights

We distribute “compliance cards” to employees to provide education on the importance of respect of human rights.

Labor Practices

The basics of safety and health

The Mie Plant obtained Occupational Safety and Health Management System (OSHMS) certification in accordance with Japan Industrial Safety & Health Association (JISHA) standards in 2006. In addition to improvement activities that reduce risk via a pursuit of genuine equipment safety, focusing on the issue of communication, this system has as its pillar the creation of people who possess the “safety” mindset.
With respect to plant safety and health policies, the basis of our operations is as follows: “The basis of corporate activity is assuring the safety and health of workers. We will prioritize the safety and health of each individual employee so as to realize workplaces in which employees can enjoy physical and mental health and comfort, through the appropriate, effective operation of labour safety and health management systems in collaboration with employees.”

Creating safe equipment

Using risk assessment methods, we are promoting the identification, evaluation and improvement of potential danger sources; we are also implementing measures that include the isolation of sources for danger from work areas and promoting the creation of people-friendly facilities.

Safety awareness

We pursue safety as a top priority under all circumstances. Specifically, we have shifted from collective guidance to individual guidance, and we conduct one-on-one safety education, dedicated safety time activities, and reviews of work procedures in open work observation.
In addition, we view successor development as a priority issue, and we are working to improve skills through various types of training.
We conduct activities suitable for the mind of each and every individual through thorough decluttering and organizing and the revitalization of communication.

Creating energetic workplaces

We give a variety of different awards even for small achievements. We do this irrespective of what job titles recipients hold. Numerous improvement suggestions from the factory floors have been successfully developed into safety enhancement measures by encouraging people to challenge themselves, rather than fear failure.
Regarding mental health, discussion meetings have been held with 15 people per month, and stress checks have been continued and analysis conducted to lead to improvements in the workplace environment.
One of the health promotion measures that we have implemented is the Quit Smoking Challenge. Starting in 2016 with a baseline level of 49.7% of employees being smokers, we have taken a series of steps since then. One day a month is designated as “Quit Smoking Challenge Day,” and we also distribute nicotine patches to employees who want them, and provide lung age checks. As a result, by 2018 we had brought the smoking rate down to 45.5%. For 2019, we are formulating quit smoking plans, with implementation periods of up to six months, for every team, regardless of which section or process it belongs to.

Employment of people with disabilities

Concerning the employment of people with disabilities, as part of our efforts to strengthen links with special needs schools in the area, we have accepted one internship, with the aim that this will lead to eventual hiring.

Reporting on chemical substance management status

The Mie Plant verifies whether all materials handled at the plant (raw materials, secondary materials, and auxiliary materials) contain chemical substances subject to Safety Data Sheet (SDS) requirements, and in the case of substances where the amounts handled exceed the thresholds specified by the PRTR Law, annual reports are submitted to the national (or prefectural) authorities and safety impact assessment is performed. Regarding the handling of substances pursuant to the PRTR Law, please refer to the Safety Evaluation Table of Domestic Production Bases.
In addition, to enhance the overall level of chemical substance management, we conduct compliance verification by implementing chemical substance assessment that covers risk of adverse impact on employee health, risk of explosion or fire in relation to equipment and machinery, and environmental risk.

Efforts for Biodiversity Conservation Activities

Tree-planting activities were continued in fiscal 2018 with respect to the following locations: (1) Forever Forest Project planting activities (Mie Plant), (2) Company Forest planting activities (Taiki-cho, Mie), (3) Cleanup of Seta River (Ise City), (4) Hinokijiri River (Ise City), (5) Ominato Coast (Ominato-cho, Ise City) and (6) Biotope (Mie Plant).
At the three locations denoted (4), (5) and (6), our teams carry out team activities and workshops that are conducted by employees above the level of supervisory manager. The team activities take place on the monthly biodiversity conservation activities day, while the workshop takes place once every four months. At these workshops, with respect to activity reports and illustrated books, each of the teams shares their information. As activities that involve the entire plant, we also conduct clean-up activities twice a year with neighborhood associations and representatives of the local government. In addition, a biodiversity protection activities report meeting is held with neighborhood associations and representatives of the local government once a year, at which opinions are exchanged.
Furthermore, with respect to protection activities conducted at (5) Ominato Coast, a preparatory class was held for the benefit of fourth grade students at Ominato Elementary School. During these classes we discussed the creatures of the Ominato Coast. We also held a “pulling competition” to remove an introduced species called Oenothera laciniate (commonly known as the cut-leaf evening primrose).
At (6), visits were made to four elementary schools to give courses on biodiversity conservation activities at the new biotope (Mie Plant).

Responses to comments and complaints received in FY2018

Suggestion

The road by the side of the logistics warehouse has been affected by subsidence, so that whenever large vehicles go down it there is a loud noise. This road should be repaired as soon as possible.

Response

Regarding the truck noise, we have examined the environmental monitoring sheet and confirmed the locations where subsidence has occurred. We will follow your suggestion and implement repair as soon as possible.

Suggestion

During the Northern Osaka Earthquake of 2018, a child was killed by a collapsing wall. Although the walls at the Mie Plant are low, there is one section where the wall is damaged. As the wall juts out into the road at that point, it should be repaired.

Response

Social gathering with local residents

Regarding the wall, it was inspected on the day of the Northern Osaka Earthquake, and on the day after. When the faulty section was discovered, the facilities manager immediately arranged for repairs to be made. The work will be completed by the end of fiscal 2018.

Fair Operating Practices

Certification of new business partners

Guidelines are established on compliance with human rights, legal compliance, and safety and environmental activities, etc. when business is to be commenced with a new business partner. Based on such points, the approval processes for the appointment of a new procurement partner are undertaken, and interviews are conducted while various materials are referred to. It is through this process that business partners are selected.

Communication with business partners

CSR study meetings

There is an organization at the Mie Plant comprised of cooperating companies called the “Isuzukai.” It holds gatherings for officers from these companies, etc., at which requests and opinions are mutually exchanged. Furthermore, CSR study meetings and safety training sessions are also held annually, with the aim of realizing mutual improvement in relation to CSR-aware management.

Consumer Issues

Safety and quality of our products and services

Using as a pillar the principle of “creating quality through the eyes of the customer,” at the Mie Plant we promote the continuous improvement of products and services by leveraging the quality management system ISO/TS 16949 (moved to ISO 9001 and IATF 16949 from June 2018) as our operational basis. We regularly confirm the effectiveness of this system through internal systems audits and external reviews that are conducted every six months.
In addition, by using “Quality Maintenance Activities” to ensure effective self-directed quality management throughout the entire production process, etc., we position quality as customer safety while working to ensure that all employees are conscious of the “eyes of the customer” being on them.
With respect to products, we are proactively shifting our efforts towards environmentally-friendly products, for example through the enhancement of tires with reduced rolling resistance, improved wear functionality, and excellent durability and ultra-wide tires.
