▼ Exhibition Overview

We will be exhibiting at “Sewerage Expo ’26 Tokyo,” Japan’s largest trade show in the sewerage sector, to be held at Tokyo Big Sight from Tuesday, August 4, 2026, through Friday, August 7, 2026.

This exhibition brings together the latest technologies, equipment, and services designed to address the challenges faced by local governments and sewerage-related companies across the country.

Faced with numerous challenges—including aging sewer infrastructure, the need to respond to frequent heavy rains, and a severe shortage of on-site workers— nat proposes a solution to improve operational efficiency using 3D scanning technology, under the initiative “Infrastructure and On-Site Digital Transformation Starting with Just One iPhone.”

nat (Live Demos)

At nat, we will be showcasing Scanat,” an app that allows you to perform high-precision 3D measurement and modeling using only your everyday iPhone or iPad, without the need for expensive specialized equipment.

On the day of the event, we will be offering a “live demo” where you can experience scanning that simulates the process of surveying the current condition of infrastructure and structures.

・Streamlining Infrastructure Maintenance and Condition Surveys ( Scanat ): Instantly captures 3D data of the current condition of manholes, manhole pumps, complex structures within treatment plants, and more. This completely prevents “rework” caused by missed measurements on-site.

・Streamlining drawing creation and digital twin development: You can extract DXF files from scanned 3D data. This dramatically speeds up the process of creating drawings and building digital twins for older sewer facilities or job sites where existing drawings are no longer available.

・Passing on technical expertise to younger staff and sharing on-site conditions remotely: By utilizing 3D models and 360-degree panoramas, on-site conditions can be instantly shared visually with the office. This allows the expertise of veteran technicians to be visually passed on to younger staff and facilitates the smooth sharing of information with office staff and relevant parties.

◼︎Recommended for people like this

This is especially recommended for those in the sewerage industry and infrastructure maintenance who are facing the following challenges.

⚪︎Representatives of local governments and public organizations (responsible for infrastructure longevity plans, disaster recovery, and the promotion of digital transformation in sewer system management for local governments)

⚪︎Design and consulting professionals (reducing the time spent on as-built surveys and investigations; exploring ways to utilize 3D point cloud data)

⚪︎Maintenance and construction companies, and site supervisors (to address labor shortages, streamline site surveys, and implement safe, contactless measurement methods)

■Introduction to Exhibited Products

" Scanat," a 3D scanning app

Defying the conventional wisdom that “laser scanners are too expensive to set up” and “too difficult to operate,” this solution will dramatically transform infrastructure surveys using just a single iPhone.

With just a few minutes of scanning by a single person, you can take measurements within 3D models, calculate areas, and export CAD files such as DXF.
From complex processing facilities and piping systems to disaster recovery sites, this solution eliminates the need for return visits due to missed areas during scanning and significantly reduces lead times for survey, design, and maintenance operations.

"I want to get started with 3D and digital infrastructure in a simple way"
"I want to improve both on-site safety and work-style reform right away"

Our entire staff sincerely looks forward to welcoming you all.
