In the areas afflicted by anti-personnel landmines, Komatsu has engaged in activities to support community development throughout the process from demining to reconstruction. Utilizing Komatsu’s demining machines and construction equipment, developed by combining its technical expertise, knowledge and experience in manufacturing, Komatsu started its project in Cambodia in 2008 partnering with the authorized NPO "Japan Mine Action Service" (JMAS) and another project in Laos in 2016.
From a land contaminated with dangerous landmines to a land where people can live in safety and security, and further on to a land with added value through the construction of roads and elementary schools. Komatsu will continue to promote activities that contribute to the independent reconstruction of the entire community by providing support through construction equipment, which is our core business.
Clear landmines from the vast tracts of land. In the aftermath of war and civil war, landmines and unexploded ordinance remain in many areas in Cambodia. Still today citizens continue to suffer severe injuries and even death from landmines. Buried in the vast tracts of land near the Thai border in the northwestern part of the country are countless anti-personnel landmines, preventing restoration and development. In order for people to return to the abandoned farmlands and deserted villages, our clearing of the landmines and making the land safe to live and walk upon must be our first task.
By restoring farmland and roads, people regain their livelihoods. The Project does not end with the clearing of landmines. That step only restores the land’s ability to fulfill its role in the development of farmlands or construction of roads. The two main crops of Cambodia are rice and cassava. For efficient cultivation and harvesting, land intended for rice paddy-use needs to have the unevenness of the ground and other irregularities eliminated. The result of using bulldozers equipped with ICT to level the land and prepare it for rice paddy cultivation and harvesting is a nearly doubling of yield. In addition, irrigation canals and reservoirs have been created to alleviate water shortages. Previously farming in the dry season was not possible. Now more and more farmers are enjoying access to water from irrigation canals for their crops. Moreover, construction of a network of new and improved roads connects farmers not only with towns and the region but also with vital lifelines. The impact of all these improvements is large. People living in villages are choosing to stay. Those who left to find work in other countries are returning to build prosperous lives on the reborn land. Soon the newly constructed roads will be busy with people coming and going between home and villages alive with hope and vitality.
"Learning is creating your future". That is what the principal of a local elementary school said to his students. There was a child who gave up going to school because the school in the minefield was far away. There were also schools where the school buildings were so dilapidated that it was difficult to study. It has been more than ten years since we started building elementary schools. Some children have graduated from the first and second schools and are now college students. A small bud seemed to open into a large flower. People gather in places that used to be minefields, schools are built, and students learn. Each person will find their own dream. That's why children's smiles shine so brightly.
As of the end of March 2026, Komatsu had been involved in the construction of a total of 12 elementary schools in Cambodia. All of these schools were built on former minefields, and many of their students come from economically disadvantaged families. Some students have gone on to attend university after graduating from elementary school. In response, Komatsu launched a new scholarship program in FY2022 for graduates of the elementary schools built by Komatsu. In FY2025, 21 students received scholarships through the program, and in FY2026, 28 students are receiving scholarships through it.
In May 2024, a study tour was conducted to visit demining sites and reconstruction areas, targeting Komatsu Group employees and their families. The tour, which focused mainly on employee-participation CSR activities, welcomed a total of 45 employees and their families. In addition to observing Komatsu construction equipment at work in minefields, agricultural lands, and infrastructure development sites, the group visited an elementary school built with Komatsu's support. At the schools, participants engaged in activities such as painting, repairing desks, and interacting with students through science experiments and a tug-of-war game.
We started support of unexploded ordnance disposal activities in 2016 in Xiangkhouang province, northern Laos.
In Laos, more than 30% of the land is contaminated with unexploded ordnances, mostly cluster munitions, which harm children and farmers every year. Komatsu plays its part by offering the necessary machines free of charge for the mechanized operations jointly conducted by UXO-LAO (a Lao unexploded ordnance disposal squad) and the Japan Mine Action Service (JMAS), alongside engineering support for the machines it provides.
In July 2025, Komatsu provided two demining machines to the Government of Senegal through Japan’s Official Development Assistance (ODA) program. In Senegal’s Casamance region, although a ceasefire was declared in 2014 following a civil conflict that began in 1982, antipersonnel landmine-related accidents continue to occur. Several once-thriving villages in the region were abandoned as residents fled. The purpose of Komatsu’s support is to help restore these villages, enable the return of displaced residents, and contribute to the rebuilding of new communities.
In addition, as part of its human resource development initiatives, Komatsu has been providing scholarships since October 2025 to students enrolled in the Heavy Machinery and Construction Equipment Maintenance course at the Centre de Formation Professionnelle et Technique SENEGAL-JAPON.
As part of its “Visiting Lecture” initiative, Komatsu employees visit schools in Japan to introduce the activities of the demining project to a wide range of young people, from elementary school students to university students. As of the end of March 2026, Komatsu had conducted 156 lectures for around 14,000 students, including lectures held online.
Feedback from high school students included the following comments:
“I learned that Komatsu, a construction equipment company, is expanding its support to regions such as Cambodia by collaborating with governments and JMAS. This made me realize that any field may hold many possibilities. I would like to keep in mind that working together with various people can broaden possibilities in many different directions.”
“Even when we talk about ‘social contribution’ or ‘international contribution,’ I realized that there are countless challenges, as well as many organizations and people working to address them. I have a major aspiration to contribute internationally in the future, and I now understand that there are many possible paths in addition to the one I am currently considering.”
Komatsu will continue to provide visiting lectures so that children, who will lead the future, have opportunities to think about world peace, their own futures, and how they wish to live their lives.
