Notice of participation in the "Hokkaido Civil Engineering and Architecture Future Technology Exhibition 2025" from July 2 (Wednesday) to July 3 (Thursday), 2025.

For tunnel construction and night work! Displaying highly visible virtual signs to contribute to safety management.

The Virtual Sign is a system that projects pre-set signs from a high-brightness light source mounted on the main device, by setting the signs in advance on the cloud at the site office or similar locations. By brightly and clearly projecting signs at tunnel construction sites or nighttime construction sites, it effectively informs site workers of restrictions and raises awareness. Various sign contents for use at construction sites are prepared, and the display content can be changed remotely via the cloud, reducing the hassle of installing or replacing signs and leading to labor savings. The main device is equipped with a communication terminal, and the connection to the cloud can be selected from LTE, wired LAN, or Wi-Fi. It is also possible to project sensor information and surveillance camera footage installed at the communication site via the cloud. Additionally, it has dustproof performance that allows it to be used without impact in tunnel construction, as well as waterproof performance for use in rainy weather. By projecting images from a high-brightness light source, it is possible to create large and clear sign displays, similar to projection mapping, by installing the device in locations that do not obstruct vehicle traffic.

Eliminate the troubles of dead zones where radio waves do not reach!

【NETIS Registration Number】KT-240171-A Enables the establishment of wireless LAN in outdoor environments without communication infrastructure. You can choose satellite, optical, or LTE lines as the starting internet connection, and by combining wireless Wi-Fi access points, it allows for the construction of wireless networks in areas where communication is unavailable, such as in tunnels under construction or during sediment control dam work in mountainous regions, within the areas required by customers. We provide optimal solutions tailored to the site environment and usage scenarios. We will strongly support the improvement of productivity in the construction industry through the promotion of the introduction of construction DX technology in communication-deprived areas. 【Features and Characteristics】 ■ Ideal for remote presence in communication-deprived areas! ■ Communication methods include three types: satellite, optical, and LTE lines ■ Combinations can be tailored to applications and purposes ■ Wi-Fi areas can be easily set up at any desired point ■ Highly flexible solutions can be constructed *Please feel free to contact us via the "Contact Form."

Reduce working hours by approximately 50-70%! Significant improvements in productivity and work efficiency with AR rebar inspection that can be conducted by one person.

【NETIS Registration Number】CB-230022-VE 'BAIAS' is an AR system for rebar inspection of reinforced concrete structures that allows a single person to easily conduct inspections using a tablet. By automatically measuring the number, diameter (thickness), and spacing of rebar from images taken with a tablet, it significantly reduces the time and effort required for inspections. This system enables what was traditionally a multi-person task of inspecting rebar in reinforced concrete structures to be performed easily by one person, contributing to labor-saving and efficiency on site. 【Features】 ■ Measurement of rebar spacing is possible even with double rebar ■ Supports measurement of cover thickness ■ Contributes to labor-saving in the inspection process with the electronic blackboard function ■ Reduces preparation and work effort with the two-point measurement function *For more details, please refer to the PDF document or feel free to contact us. *This product is for the domestic market.

You can check measurement data from a remote location! Automatically calculates the temperature difference between the surface and the center of the concrete.

【NETIS Registration Number】KT-230101-A The "Ondroid Temperature and Humidity Measurement System" allows for the setting of alert values for each measurement location. When the measurement data exceeds the alert values, the responsible person can be notified via email. It automatically calculates the temperature difference between the surface and the center of the concrete, which can be a factor in temperature cracking, and when the temperature or humidity at specific locations exceeds the alert values, it can automatically activate the irrigation pump or jet heater, leading to increased productivity through labor-saving measures. Please feel free to contact us if you have any requests. 【Features】 ■ Data differential monitoring function ■ Temperature difference monitoring function ■ Linkage with irrigation pumps and jet heaters *For more details, please refer to the PDF document or feel free to contact us.

~ A high-efficiency customer attraction strategy where homebuyers come in saying "I saw it on ○○!" and a product/design strategy that is specifically requested with "I want to build with Harbor!" ~ In an era where simply creating a "good house" is not enough to survive, the environment surrounding local construction companies is becoming more challenging than ever due to rising material costs, labor shortages, and intensified competition with major companies. In this context, Harbor House, which has been established for 19 years in the fiercely competitive Niigata Prefecture, has achieved an annual completion of 450 houses and is now ranked number one in the number of construction starts in Niigata Prefecture. Its strength lies not in a single charismatic leader, but in a thoroughly refined "system." Customers who say, "I came after seeing your website" are reliably guided to contracts through a highly efficient sales flow based on "batting average management." In this online seminar, we will generously share the know-how of customer attraction, product, and management practices that Harbor House implements with business owners. We will present the shortest route to becoming a "construction company that continues to be chosen" in your business area. ◇ Detailed information and application https://x.gd/pUe2b ◇ Phone inquiries TEL: 025-383-8881

The demonstration showcases a variety of AI solutions, including AI-equipped PCs, workstations, the Japanese facial AI avatar "Aine," digital assistants, the compact desktop "Dell Pro Max with GB10" (equipped with NVIDIA GB10), rack-mounted solutions, and conference audio equipment. Digital assistants are already being implemented across a wide range of fields, including finance, healthcare, government agencies, and local municipalities, with expanding applications in marketing, customer service, and operational efficiency. This exhibition provides a valuable opportunity to directly see how "Aine" can contribute to solving business challenges.

"Connecting technology and field knowledge to accelerate implementation" We provide a space to co-create "solutions that can be used from tomorrow" by merging real challenges from the field with cutting-edge digital technologies (spatial, ground, DX), going beyond mere technology demonstrations. 【Event Overview】 Date: June 5, 2026 (Friday) Main session 13:30–17:30 Networking event: 17:45–19:45 Format: Akihabara Hall (3 Kanda Neribeicho, Chiyoda-ku, Tokyo) or Zoom webinar Expected attendees: 200 people Speakers: International Kogyo Co., Ltd. / Texar Co., Ltd. / Just Co., Ltd. / Toshiba Lighting & Technology Corporation / Ground Network Holdings Co., Ltd. / Nihon University College of Science and Technology, Department of Architecture Special website for the conference:
