Added a rockfall protection net "Neolock Net" with a pile foundation structure to minimize land acquisition on the mountain slope.
We have newly added a new (Neo) rockfall protection net, "Neo Lock Net," which solves the challenges of traditional rockfall countermeasures, to our product lineup and have begun sales. The Neo Lock Net is a post-type rockfall protection net that covers slopes with a risk of rockfall using wire mesh and wire ropes, safely guiding falling rocks to the bottom. It employs a self-supporting post structure based on pile foundations, eliminating the need for support materials such as mountain-side anchors or guy ropes. Additionally, it is possible to install a single-pipe scaffold for wire mesh installation work on the posts, enhancing safety and workability during high-altitude operations. The structure integrates the capture and guidance of falling rocks, absorbing rockfall energy with the wire mesh that covers the slope from the stopping surface. By adding this post-type rockfall protection net to our lineup, we will flexibly respond to various needs on site.

Added "Bam Guard," a bamboo prevention fence to prevent bamboo damage that poses a danger to the road.
We have newly added the bamboo prevention fence "BamGuard" to our product lineup, which prevents damage from fallen bamboo to roads and ensures road traffic safety, and we have started sales. BamGuard is primarily installed along roads to catch bamboo that may fall due to strong winds or heavy snowfall. It is an ideal construction method for preventing road closures caused by fallen bamboo, ensuring safety for road users. With a simple structure and fewer components, it improves workability and reduces costs. Additionally, there are two types of post foundations available—"anchor foundation type" and "pile foundation type"—which can be selected based on site conditions, allowing for flexible responses to various situations. By adding the bamboo prevention fence to our lineup, we will flexibly address various needs at the site.

Activities related to the dissemination of road slope disaster prevention technologies and methods in the Kingdom of Bhutan.
Our company implemented the "Dissemination, Demonstration, and Business Development Project for Road Slope Disaster Countermeasures Technology and Methods in Bhutan" under the Japan International Cooperation Agency (JICA) from August 2019 to June 2023. The Kingdom of Bhutan has about 70% of its land in mountainous areas, exposing it to risks of falling rocks and landslides, with slope disasters frequently occurring on its main infrastructure, the roads. This not only causes human casualties and creates isolated areas, but also significantly impacts local industries due to road disruptions. Furthermore, the lack of specialized engineers for rockfall and landslide countermeasures in the country, as well as the absence of companies capable of designing and constructing countermeasure facilities, poses a major challenge. In response, our company has worked on local demonstrations of products to stabilize road traffic and support steady economic development. Specifically, we installed two products, "Geo-Lock Wall" and "Macro Net," on-site. These efforts contribute to reducing human casualties from slope disasters, improving logistics efficiency, and fostering regional economic growth through industrial development. Moving forward, we will continue our activities to promote slope disaster countermeasure technologies and methods on roads in Bhutan and surrounding South Asian countries, contributing to economic development.
