Under the slogan of "Caring for the Future," the Yokohama Rubber Group is engaged in various activities that contribute to CSV with society by addressing social needs and issues around the world.

• CSV: Creating shared value

The "Yokohama Magokoro Fund", which was established by a group of employees in 2016, collects reserve funds from employees who support and voluntarily join the fund (they can start contribution from 100 yen per month). The collected money will be donated to assist social working organizations or to help with disaster relief efforts. The Magokoro Fund system is unique in that the fund collects the same amount of money from the company for each amount contributed by the fund members. This system is called a "matching gift" scheme.
As of the end of December, 2025, around 39.3% of all the Yokohama Rubber employees are registered members of the fund.

Local car-sharing initiatives and disaster relief efforts

Yokohama Rubber has been donating tires to the Japan Car Sharing Association as part of its support for local car sharing initiatives and disaster recovery efforts since 2015.
The association began providing car-sharing support to temporary housing residents and evacuees immediately after the Great East Japan Earthquake as part of its disaster recovery assistance.
Today, it has expanded its services to include vehicle loans for individuals facing financial hardship and for regional revitalization, as well as free vehicle loans to support the rebuilding of lives for those who lost their cars in natural disasters. These programs utilize tires donated by Yokohama Rubber.
The replacement of tires donated in spring and fall is carried out as part of the “Student Maintenance Project” within the Automotive Course of the Department of Mechanical Engineering, Faculty of Science and Engineering at Ishinomaki Senshu University.
This initiative also contributes to nurturing the next generation who will support the future of the automotive industry.

Support for Natural Rubber Procurement in the Philippines (Yokohama Tire Philippines, Inc.)

YTPI provides ongoing support to the Philippine rubber industry and local suppliers.
Production reached 10 million units in fiscal year 2024, significantly increasing local natural rubber procurement to 13,200 tons.
This means 52% of the natural rubber was procured from local suppliers in the southern Philippines. ( Picture 1)
Furthermore, with the implementation of the European Union's (EU) Deforestation Regulation (EUDR) approaching, local processors have been implementing measures to ensure they can meet the EUDR's stringent requirements.

• Free access to the RubberWay Platform... Self-registration of geographic location information
• Support for local suppliers and smallholder farmers... Premium pricing for EUDR compliance, sharing best practices from other regions
• Collaborative roadmap for EUDR compliance... Yokohama Rubber Singapore (YRS) and YTPI are developing a roadmap to achieve EUDR compliance in collaboration with local suppliers

YTPI participated in the “International Rubber Conference” held in Davao in September 2024.
Hosted by the Philippine Rubber Industry Association (PRIA), the participants shared the needs and challenges facing the local rubber industry under the theme “Rubber: New Frontiers, New Markets.” ( Picture 2)

YTPI also actively promotes localization in various areas other than the procurement of raw materials, such as the local procurement of equipment maintenance and mold repair services. In selecting suppliers, YTPI conducts checks on their compliance and service quality.

Promoting agroforestry (Y.T.Rubber Co., Ltd.(YTRC) in Thailand)

YTRC, a natural rubber processing company in Thailand, is promoting agroforestry practice among small-scale farmers (smallholders) who grow natural rubber (para rubber trees) in the farms in areas around the factory in the Surat Thani Province in southern Thailand.
Agroforestry farming is a form of mixed cultivation that enables smallholders to harvest agricultural products other than rubber tree sap and secure a more stable source income by growing other crops beside para rubber trees. By promoting agroforestry farming, YTRC is working to maintain a good balance between financial and living stability of the smallholders versus biodiversity and forest preservation.
Furthermore, we are cooperating with agroforestry farming experts at universities to supply saplings to an experimental farm run by YTRC. YTRC also provides more than 10,000 saplings that they have grown from seeds to local schools, institutions, and individuals that want to grow them every year. This activity has earned good appreciation in the local communities.

In order to provide continuous support to the smallholder rubber farmers, YTRC has been holding regular seminar events to improve the quality of natural rubber in collaboration with the Rubber Authority of Thailand (RAOT), which is under the jurisdiction of the Ministry of Agriculture and Cooperatives of Thailand.
In January 2020, Yokohama Rubber signed a Memorandum of Understanding (MOU) to cooperate with RAOT to support the management of natural rubber farmer and ensure supply chain transparency and soundness. The above-mentioned seminar events are organized as part of our farmer support under this MOU.
We successfully hosted two seminars in 2025, reaching 50 local farmers per session in the Suratthani region.
The sessions provided in-depth knowledge on the selection and planting of natural rubber saplings, the objectives and benefits of fertilization, and the critical importance of preventing foreign matter contamination.
Additionally, fertilizer developed using Thai Natural Rubber Authority's (RATO’s) expertise was provided free of charge.
This seminar event has received high praise from RAOT as a sustained initiative.

Heisei no Mori" Project (in Otsuchi Town, Kamihei County, Iwate Prefecture)

In 2007, Yokohama Rubber launched the "YOKOHAMA Forever Forest" program to plant trees at all of its production sites in Japan and overseas in preparation for its 100th anniversary in 2017. The "Yokohama Forever Forest" program is an initiative planned and implemented under the guidance of the late Akira Miyawaki, a world-renowned plant ecologist and Professor Emeritus at Yokohama National University (official position at that time of the program), who has organized tree planting projects at more than 1,700 locations in Japan and overseas. At each location of our Forever Forest Program, we plant local native tree species that have been growing in the region for centuries and are best suited to be planted in the area. By doing so, we aim at creating groves of trees that will last and thrive for another 1,000 or 2,000 years in that place. We have originally set a goal of planting, without disturbing the existing vegetation of the place, 500,000 saplings at our production and sales sites in Japan and overseas by 2017, where the company celebrated its 100th anniversary. Under the Program, our group employees and local residents continuously worked side by side to plant trees at and around 14 of Yokohama Rubber sites in Japan and 21 sites in eight other countries. In September 2017, we reached the originally planned target of planting 500,000 saplings, but the program is still being continued toward a new goal of planting or giving away a cumulative total of 1.5 million saplings by 2030.
After the Great East Japan Earthquake in 2011, Mr. Miyawaki conducted a series of field surveys in the affected areas and proposed the creation of a "Forest Seawall to Protect Lives" stretching over a distance of 300 kilometers along the Pacific coast of the Tohoku region. Traditionally in Japanese seacoast areas, Japanese black or red pines have been used to create tide protection groves along the seashore as these tree species are resistant to salty wind from sea and grow quickly even in nutrient-poor soil. However, recent findings indicate that these pine trees can be easily uprooted when subjected to massive tsunami waves since their roots do not have a very strong soil gripping capability. Once uprooted from the ground and made adrift, the drifting pine trunks and branches can become a safety hazard that injures people and damage buildings. Mr. Miyawaki studied the trees and groves in the tsunami-stricken areas that stood near the seashore and survived the tsunami attacks to find that they had formed multi-layered plant communities consisting mainly of evergreen broad-leaved trees. Based on these findings, he proposed to local governments in the affected areas to build seawall structures with these types of trees to save lives should a similar disaster strike again. A number of local governments responded positively to his proposals.
Yokohama Rubber, having become an enthusiastic supporter of Mr. Miyawaki's vision for "Forest Seawall to Protect Lives" and wishing to make good use of its forestation knowledge and skills obtained through its Forever Forest Program to help drive the vision forward, built a tree-planting mound in Otsuchi Town, Kamihei District, Iwate Prefecture in 2012, using earthquake debris including woody debris, earth and sand, and soil-based noncombustible debris such as concrete fragments, There we organized a public tree planting event as a model case of building tree-covered tide protection structures. Such use of earthquake debris has a number of potential benefits: Firstly, it will help reduce debris disposal cost for the municipalities and will also curb CO2 emission by reducing the amount of debris incinerated. Secondly, having a mixture of various debris in the soil will accelerate the sapling growth and will also help them grip the soil more strongly. Lastly, using debris from the earthquake in the tide protection structure will help keep a keen disaster awareness among the residents. In the following year, this planting area was newly named "Heisei no Mori, and employees of Yokohama Rubber have helped the project in various ways including collecting tree seed nuts and growing them into saplings for more planting and holding a tree planting event jointly with local residents every spring.

From 2014 on, along with the annual tree-planting event in spring, Yokohama Rubber employees has been giving tree-planting training sessions to students of Otsuchi Gakuen School (run by Otsuchi Town) as part of their Hometown Study Class, which is an education program connected to post-earthquake reconstruction. In the training sessions and along with providing tree-planting experience, we communicate to the children the importance of having disaster awareness, knowing about and contributing to global warming slowdown and the significance of biodiversity preservation efforts. This is an example of the wide scope of involvement we have had in the Heisei no Mori project beyond just planting trees.
Although there have been interruptions during the COVID-19 pandemic, a total of nine tree-planting events have been held to date, and over the course of 10 years, approximately 25,000 saplings (6,000 as part of the Hometown Study Class activities) were planted on the mound, which is a raised structure 5 m high, 15 m wide and 300 m long. The Heisei no Mori project was completed in April 2022.
Yokohama Rubber continues to perform mound maintenance in Ōtsuchi Town every year (three times per year) with local volunteers, including weeding and repairing deer fences, even after the trees have been planted.

“Heisei no Mori" Project (in Otsuchi Town, Kamihei County, Iwate Prefecture)

1. To create a "Forest Seawall" to help protect residents from future Tsunami attacks. The tsunami caused by the Great East Japan Earthquake blasted past or destroyed many breakwater structures and seashore tree groves that should have protected the communities from tsunami damages but did not. A seawall of trees created by planting native tree species in a way that maximizes their natural vegetation characteristics, trees that will grow dense foliage and branches (they have wind/sand-preventing functions) as well as strong roots deep into the ground, are hoped to provide a better protection against tsunamis.
2. To help raise disaster awareness of the local residents by providing tree planting experience on the specially prepared mound created with earthquake debris
3. To revitalize communication across the local community by holding a public event where a large number of residents can get together
4. To help educate of schoolchildren and students in the local community by providing tree planting classes as part of their Hometown Study program
5. To contribute to global warming mitigation by planting more trees that absorb and fix CO2
6. To help preserve biodiversity by planting a variety of tree species in a way that maximizes their natural vegetation characteristics
