Message from the President

Masaki Nakamura

The Company was established in July of 1970 as a result of it being spun-off from the Information Systems Division of Yokohama Rubber.

With our advanced information technology skills, our reliability as people, and the numerous wonderful human resources that we’ve developed, the Company has transformed itself to become a trusted business partner which possesses the ability to respond to the diversified needs of customers.

Commencing with our acquisition of ISO 9001 (quality) certification in December 2002, the Company has endeavored to develop socially responsive systems. This strategy has included the acquisition of Privacy Mark certification (October 2006), and ISO 14001 (environment) and ISO 27001 (information-security) certification (both February 2007), etc. Moreover, while recognizing marketing communications and product liability as the most serious issues, in that it represents the Yokohama Rubber Group CSR Management Vision, the Company aims “to build a trusted identity as a contributing member of the global community.”

Organizational Governance

Corporate governance systems

In accordance with regulations, decisions involving the entire company are decided upon both at meetings held by the Board of Directors (as needed) and at management meetings (held monthly).
Each year, in addition to formulating medium-range plans and announcing them to all employees, at the unit policy announcement meetings, the various managers announce the unit policies for each financial year.

Compliance measures

ISO/IEC 27001 Certificate

A program of e-learning is implemented to provide all employees with compliance training. The person responsible for promoting compliance confirms the status of legal compliance and reports their findings each month.
Security measures are strictly conducted in accordance with the information security management system (ISMS) certification that the Company has already acquired.
Issues are taken very seriously when they are identified through internal or external audits, etc., and we work quickly to implement responses.

Business continuity

In the event of a serious disaster, accident, or other unforeseen event, we will place the highest priority on human life, ensure the safety of our employees and their families, and take measures to minimize its impact. We will then do our utmost to continue our business, thereby earning the trust of our customers and fulfilling our corporate social responsibility.

Human Rights

Antidiscrimination measures

Concerning discriminatory behavior such as sexual harassment and workplace bullying, etc., in addition to calling attention to such issues through our compliance training, the Company is responding by the establishment of a point of contact that shall be able to offer consultations.

Health and productivity measures

We are actively working to reform the way we work under the banner of health management. We have introduced a wide range of teleworking programs, including a telecommuting system, to create a system that allows employees to work regardless of their environment.
In February 2022, we continued to receive the highest level "AAA" of the "Yokohama Health Management Certification" sponsored by the City of Yokohama, and in March of the same year, we were recognized by the Ministry of Economy, Trade and Industry as an "Excellent Health Management Corporation 2022" for the fourth consecutive year.

At the Shimbashi Office, we participate in emergency drills that are held once a year by Yokohama Rubber. At the Mishima Office, emergency drills are conducted once a year. The drills assume the occurrence of disasters such as earthquake, tsunami, or fire, and they are participated in by most employees and partner company employees regardless of whether they are engaged in meetings, training, or meetings with customers, excluding times when it is decided they will be absent in advance.
We have supplies of emergency food enough for 3 days, and the expiration dates are managed.

Occupational safety and health

In fiscal 2021, there was one commuting accident (no work-related accident), but fortunately it was not serious.
The Company is working to strengthen consciousness as to the need to create safe and healthy workplace environments. In aiming to improve the operations of various workplaces, we have implemented a “visible approach” whereby it is possible to understand the extent to which plans have been achieved. We are taking steps to improve the quality and efficiency of operations, while also working to reduce “near misses,” etc.
Furthermore, concerning the issue of employee overwork, in accordance with the “36 Agreements” regarding overtime and holiday work (which relate to Article 36 of the Labor Standards Act), in addition to reports being made to monthly corporate business meetings, etc., measures have been put in place whereby overwork cases undergo interviews with industrial physicians.
