Hiroshima for Global Peace

Landes Co., Ltd.


   Using our original pre-cast concrete products to coexist with nature and build strong infrastructure


9.1 Develop quality, reliable, sustainable and resilient infrastructure, including regional and transborder infrastructure, to support economic development and human well-being, with a focus on affordable and equitable access for all

9.4 By 2030, upgrade infrastructure and retrofit industries to make them sustainable, with increased resource-use efficiency and greater adoption of clean and environmentally sound technologies and industrial processes, with all countries taking action in accordance with their respective capabilities

11.1 By 2030, ensure access for all to adequate, safe and affordable housing and basic services and upgrade slums

11.6 By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management

13.1 Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries

14.2 By 2020, sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts, including by strengthening their resilience, and take action for their restoration in order to achieve healthy and productive oceans

15.4 By 2030, ensure the conservation of mountain ecosystems, including their biodiversity, in order to enhance their capacity to provide benefits that are essential for sustainable development

15.5 Take urgent and significant action to reduce the degradation of natural habitats, halt the loss of biodiversity and, by 2020, protect and prevent the extinction of threatened species


Initiative details

We plan, develop, design, manufacture, and sell concrete products that support social infrastructure such as rivers, roads, tunnels, and dams. By doing so, we help people live safe and secure lives and create a sustainable society.
As an interface between nature and culture, the wide variety of pre-cast concrete products that we provide help to create strong yet environmentally friendly structures that ensure the safety and security of people’s lives and help to build the infrastructure that supports a prosperous society.
In addition, through joint research with Okayama University, we have developed Haresult, a resource-recycling, low-carbon, ultra-durable concrete.

In comparison to traditional concrete, Haresult has the advantages below.
(1) Five times more resistant to salt: prevents degradation of port structures due to salt corrosion
(2) Five times more resistant to frost: prevents degradation in cold regions due to frost damage
(3) Three times more resistant to sulfuric acid: prevents degradation of sewer structures due to acid corrosion (*1)
(4) Highly resistant to combined degradation (salt and frost damage)
(5) Low carbon: contributes to protecting the global environment by reducing CO2 emissions by 35% or more
(6) Resource recycling: 50% recovery of blast furnace slag (*2), a by-product of steel mills


Haresult can provide a variety of benefits depending on how it is used. When used as a base for land conservation, such as mountain and flood control, it can be used to prevent and mitigate disasters such as sudden and localized heavy rains, tsunamis, and storm surges, which have been on the increase in recent years. In addition, when used for everyday infrastructure such as schools, parks, water systems, sewage systems, and housing, it helps to ensure the safety of pedestrians and bicyclists on their way to school and to improve living environments. Furthermore, when used for industrial infrastructure such as roads, railroads, ports, and airports, it can be expected to extend the service life of public facilities and shorten construction periods.

We have also developed a small animal protection gutter called Haidasel, which is equipped with a ramp so that turtles, frogs, and other animals that have fallen into gutters or waterways can easily crawl out on their own and escape. This product is widely used in Okinawa to save Okinawa rails (an endangered species), a bird famous for being flightless, and makes a substantial contribution to achieving the SDGs as a measure to “halt extinction and biodiversity loss,” one of the SDG targets.

In addition, through the proactive use of materials with low environmental impact, involvement in the maintenance of structures, and the widespread use of environmentally friendly products, we are contributing to building a resilient country, preserving the ecosystem, and creating a carbon-free society. Moreover, by extending the service life of our infrastructure, we are helping to ensure the safety and security of people’s lives, reduce lifecycle costs, and reduce the environmental impact of congestion due to construction during product manufacturing and installation.

Key Points

In addition to ensuring people’s safety and security, we aim to help build a sustainable global environment and society by researching, developing, and bringing to market environmentally friendly products based on the concept of “co-existence with nature,” as well as promoting our own development and the happiness of our employees.
As mentioned earlier, our joint research with Okayama University has resulted in the creation of Haresult, a resource-recycling, low-carbon, ultra-durable concrete. We are also leading the Haresult Industry Association, which aims to help develop and expand social infrastructure and to promote and popularize the product.


(*1) Sulphuric acid degradation: Concrete used in sewage facilities is prone to corrosion by sulfuric acid. Therefore, the use of concrete with high sulfuric acid resistance can prevent accidents such as road sinkholes caused by the degradation of sewer pipes.
(*2) Blast furnace slag: A mixture of non-iron components such as silica contained in iron ore and the ash produced by the coke used as a reducing agent, combined with limestone as a secondary material.
