Message from the General Manager

Baba Ken

The Nagano Plant began operations in the town of Takamori in 1961.
In 2013, we began implementation of a plan to integrate the metal fittings processing and hose assembly operations of the Hoses and Couplings Division. The first stage in this project was the relocation of the functions of the Hiratsuka-Higashi plant (in Kanagawa Prefecture) to a new factory built in Toyooka Village; this relocation was completed in February 2014.
In 2015, work began on the construction of a new factory on an adjacent site; and this was completed in November 2016. We then proceeded to move the functions of the Takamori Plant to the new factory, the relocation of major production facilities was completed in June 2017, and this marked a major new step forward for us with the development of integrated production, including everything from metal fittings processing through to hose assembly.

Through machining and cutting processes that make use of equipment such as multi-axis CNC machines and NC lathes, etc., we produce oil pressure hose clasps and hose clasps for automobiles; we also complete the production of hoses produced at the Ibaraki Plant by caulking and assembling them. These products are then supplied to various hosepipe markets such as the construction machinery, machine tools and automobile manufacturing industries.
Besides being used for assembly in our own factory, the clasps that we manufacture are also supplied to affiliated plants in Japan and overseas and to other domestic customers nationwide. Furthermore, we don’t just engage in the cutting of clasps, we also undertake the assembly of self-seal couplings.

The Nagano factory is located on the east bank of the Tenryu River, in the Ina Valley with its beautiful natural scenery, bordered by the Southern Alps (Akaishi Range) and the Central Alps (Kiso Range).
Precisely because of our location in such a marvelous natural environment, we are determined to keep the burden that we place on the environment as small as possible, and we are implementing various measures aimed at combatting global warming and at contributing to the development of a recycling-based, low-carbon society through energy conservation, resource-saving and recycling.

As regards energy-saving, in addition to promoting familiar energy-saving activities both at the plant and in the homes of all employees by acting as one, by introducing and renewing power saving-type equipment within the plant and seeking to control the wasteful use of energy, we are actively striving to help prevent global warming.

A plant tour by high school students

With regard to community and CSR activities, since fiscal 2013 we have been undertaking biodiversity conservation work involving surveys of the flora, aquatic fauna and birds along the Oshima and Tenryu Rivers. Such activities will help in conservation.
On September 7, 2015, thanks to assistance provided by Nagano Prefectural Government, we signed a “Forest Stewardship Agreement” with Toyooka Village and began to undertake satoyama (traditional community-managed forest) conservation work with respect to the area around the Toyooka Village Gymnasium and Sports Ground. In 2016, our efforts in these activities received recognition in the awarding of the Shimoina Forest Association Chairman’s Prize in the Minami Shinshu Healthy Forests Awards.
Concerning the “Yokohama Forever Forest Project” that has continued since 2007, we concluded the plan for stage VI tree planting activities in 2013, and in 2016 we donated a total of 1,040 seedlings grown at the plant to local towns and villages.
For the Tenryu River which flows through the region, each year we proactively participate as a party in charge of allocations during the river cleanup (the environment picnic).
We also make effective use of opportunities for communication and exchange with the residents of Takamori and Toyooka, for example by arranging plant tours for local elementary and high school students and members of local organizations, etc. In addition to listening to what people have to say, we are working to improve understanding of the Company’s business activities and its environmental conservation efforts.

Furthermore, by visiting the suppliers who collaborate with us on the provision of materials and parts for our business, and by proactively encouraging our customers to visit us, we foster smooth, two-way communication, in line with our aim of being a factory that is able to respond effectively to every nuance of market needs within the supply chain.

Organizational Governance

Concerning decision-making, a system is in place so that monthly meetings are held for each different area. Safety and health issues are decided by the Safety and Health Committee, environment issues by the Environment Committee, energy issues by the Energy Savings Committee, and quality issues by the Quality Committee. Furthermore, Section Chief Meetings and Follow-up Meetings are held as required to make decisions on plant-wide issues. Employees are notified of the decisions made by this committee system through daily communications and by the General Manager’s Morning Meeting held at the start of each month.
As regards compliance awareness-raising activities, at the end of each monthly Safety and Health Committee meeting, the Safety and Health Section Chief (who also serves as head of the Corporate Compliance Department) uses the Department’s “Workplace Learning Session Materials” to implement education for the meeting participants. In each workplace, the members of the Safety and Health Committee implement the activities decided on at the workplace safety and health committee meetings on a plant-wide basis.

Human Rights

Supply chain relations

Regarding our relationship with our parts and materials suppliers, we visit each supplier each year on a systematic basis to perform on-site verification of the production status and quality management situation, with the aim of putting our collaboration with partner companies on an even firmer footing.
We also aim to foster effective communication with suppliers through the holding of Purchasing Liaison Meetings, Supplier Quality Coordination Meetings, and CSR Study Meetings.
Regarding our customers, by attending certified plant management meetings and hosting plant inspections, we are able to assist customers with their business operations by maintaining a clear picture of the types of products and services that our customers, and the market as a whole, require.

The Nagano Plant verifies whether 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.

Participation in the Tenryu River Environment Picnic (Cleanup)

As we do every year, we participated in the Tenryu River Environment Picnic, which this year was held on May 26. We also fulfilled an organizing role in acting as the party responsible for a block of corporate participants. (participants: 27 adults, 2 children)

Yokohama Forever Forest Tree planting Activity

With the completion of the planting of 6,905 trees, exceeding the cumulative total number in the plan, the activities were concluded in stage VI of 2013.
Although the provision of seedlings outside the company was continued after that, the continued provision became difficult after the move to Toyooka, and the activities were concluded with the donation of 1,040 seedlings to local municipalities and residents in December 2016.

Biodiversity conservation activities

As part of biodiversity conservation activities that were started from fiscal 2013, we have conducted monitoring surveys in the spring and fall of every year downstream in the Oshima River where rainwater is discharged from Takamori and near its junction with the Tenryu River, as well as downstream in the Terasawa River where rainwater is discharged from Takamori and along the agricultural-water runoff ditch located at Kono Hydrophilic Park.
Although these activities had to be suspended with the transfer of the plant from Takamori to Toyooka in fiscal 2017, preparations are underway to resume activities in fiscal 2018.

Satoyama Conservation Activity

On September 7, 2015, thanks to assistance provided by Nagano Prefectural Government, we signed a “Forest Stewardship Agreement” with Toyooka Village and began to undertake satoyama (traditional community-managed forest) conservation work. From 2015 to 2016, three rounds of work were implemented; the work undertaken included undergrowth moving and improvement cutting.
Our efforts in these activities received recognition in the awarding of the Shimoina Forest Association Chairman’s Prize in the Minami Shinshu Healthy Forests Awards in 2017.
Although these activities had to be suspended with the transfer of the plant from Takamori to Toyooka in fiscal 2017, the fourth round of activities was resumed on June 23 in fiscal 2018.

MD Squad activities

Concerning the MD Squad’s activities within the plant, they have promoted paperless business practices, OA server 2S (sorting and setting), rag cloth recovery, stored documentation 2S, and a reduction in paper purchases by encouraging the use of the reverse side of previously used paper. Additionally, they have initiated heat reduction measures in the form of cultivating curtains of greenery, etc.
In particular, concerning the measures implemented to recover and reuse rag cloth, through activities such as weeks in which such measures have been strenuously promoted, the plant is now at the point of not needing to purchase additional stocks.

Fair Operating Practices

Thorough statutory compliance

After the transfer of the plant had been completed, there was a single case of trouble being caused in that there was an oil spillage on a public road that resulted from oil escaping from old hydraulic piping that was being carried on the truck of a subcontractor. By way of response, an oil-spill cleanup was immediately initiated, and in the presence of fire brigade and city office representatives, it was confirmed that there was no risk to the surrounding environment.
We received no information regarding complaints from external sources.

Consumer Issues

Visits to local elementary schools

Road safety and courtesy class at Takamori-Minami Elementary School

On November 27 and December 20, we visited Takamori-Minami Elementary School to give classes on road safety and courtesy.
The district where our plant is located has limited public transport services, so most people rely on cars to get around. This means that the risk of traffic accidents is significant.
Our factory manufactures items that are used on cars.
For this reason, we feel that it is important to participate in this activity every year, so that we can make at least some small contribution toward reducing the risk that small children will be hurt in traffic accidents.

Workplace recreation

Workplace recreation and family interaction events are conducted annually through the cooperation of labor and management, with the aim of fostering closer communication with employees. Events are held multiple times, or on days that are a rest day for all employees, to ensure against work-shift bias.
As a workplace recreation event to commemorate the 100th anniversary of foundation, a BBQ was held three times in October to November of last fall, in which 101 people participated. Through their participation they had the opportunity to develop friendships with colleagues employed at other workplaces.
A family bus tour in the spring, visiting Nagashima Spa Land, was conducted in May, with 42 people participating. The children in the party quickly made friends with one another while the various family groups interacted.
Additionally, as workplace recreation in the fall, a bowling event was organized during which a total of 77 people participated over three separate occasions.
The event offered participants the opportunity to deepen their interactions with persons other than those they normally worked with.
