■ Growing On-Site Burden Due to Strengthened Building Asbestos Regulations

Since 2020, asbestos (asbestos-containing materials) regulations targeting building demolition and renovation projects have been rapidly strengthened.

2020

Major revision of the Air Pollution Control Law and Asbestos Ordinance (covering all asbestos-containing building materials)

2021

Obligation for general contractors to conduct preliminary surveys and apply work standards (enforced April)

2022

Mandatory electronic reporting of preliminary survey results to authorities (enforced April)

2023

Qualification requirements for conducting preliminary surveys and for analysis technicians (enforced October)

2026

Full application of qualified personnel inspections to structures (enforced January)

According to the Ministry of the Environment, the number of notifications for asbestos-containing building demolition under the Air Pollution Control Law has exceeded 27,000 annually, significantly increasing administrative burdens on site personnel.

However, on-site, many companies report that despite understanding their legal obligations, 'practical responses cannot keep pace' due to the need to report to multiple authorities and the overwhelming number of small-scale construction projects. While AsbestosONE is a service designed to solve these issues through a cloud system, there has previously been no platform for practitioners actively implementing compliance measures to share know-how across companies.

This user meeting was planned as the first initiative to create such cross-company connections.

【Presentation ①】Kajima Building Management Co., Ltd.

"Challenges in Construction Environmental Management for Building Management Companies — Toward Company-Wide Deployment and Compliance Strengthening"

Mari Yasuda, Planning Department, Building Management Headquarters, concurrently Safety & Environment Department

As a 100% subsidiary of Kajima Corporation, the company manages over 2,890 buildings nationwide (2,890 employees). It introduced AsbestosONE in July 2025, and currently over 140 employees are using the system.

Mari Yasuda, Planning Department, Building Management Headquarters, concurrently Safety & Environment Department, Kajima Building Management Co., Ltd.

The presentation focused on three on-site challenges: the overwhelming number of small-scale construction projects, reporting to multiple authorities, and deploying the system to branches with low IT literacy. It detailed the company's 10-year journey toward company-wide standardization of waste management and asbestos law compliance.

The company shared insights valuable to similar-sized firms, including the strategy of 'scaling up successful model branch cases' to enable phased deployment, and the importance of repeated explanatory sessions and meticulous Q&A support.

Additionally, a user-requested feature — 'AI agent-based asbestos presence detection (AI determines presence based on material part number input)' — was shared, drawing significant attention as a field-driven need.

【Presentation ②】Taisei Oncho Co., Ltd.

"Initiatives to Reduce On-Site Workload"

Dan Yonetani, Safety & Environment Department, Technical Headquarters, Technical Strategy Division

Founded in 1941, Taisei Oncho is a comprehensive engineering firm specializing in HVAC and sanitary equipment (581 employees individually, 784 consolidated). It operates eight branches nationwide and has affiliated companies in Vietnam, China, Australia, and the United States.

The presentation focused on three structural challenges: concentration of work on site staff amid ongoing labor shortages, dual workload from managing nearly completed projects and upcoming ones simultaneously, and complex on-site tasks in renovation work and safety documentation management. It introduced four technical headquarters-led efficiency initiatives.

Insights shared included the phased adoption of BIM using the 3D CAD system 'Rebro', a front-loading support system where a Vietnam-based affiliate handles drawing creation and equipment calculations before site deployment, significant labor reduction in measurement tasks using 3D scanners, and a centralized system where dedicated headquarters staff handle safety document review and corrective actions, allowing site staff to focus solely on consistency checks.

【Commemorative Seminar】'Illustrated Guide to Asbestos Regulatory Compliance by Work Type — The Basics'

Shinichi Koyasu, Representative Director of the General Incorporated Association for Corporate Environmental Risk Solutions (CERSI) and Head of Environmental Consulting Division, Universe Co., Ltd.

Head of Environmental Consulting Division, Shinichi Koyasu, Universe Co., Ltd.

Environmental consultant Shinichi Koyasu, who conducts seminars for over 3,000 people annually, has published the book 'Illustrated Guide to Asbestos Regulatory Compliance by Work Type — The Basics'.

As a special event, a commemorative seminar was held during the user meeting, where he explained a practical framework to help waste generators correctly understand 'who should do what'. Common challenges in regulatory compliance and strategies for maintaining continuous compliance were shared.

■ Participant Survey Results

Results from the 1st 'AsbestosONE User Meeting' participant survey

Participants commented: 'Learning about the AsbestosONE implementation process and sharing on-site challenges was extremely informative,' 'Mr. Koyasu's book addressed real field concerns,' and 'Hearing about other companies' approaches to using AsbestosONE was highly beneficial.'

■ Organizer's Remarks

Miya Hoshi, President and CEO, EMS Inc.

'Today, our long-standing wish has finally come true, and we are truly delighted that everyone has gathered here. In the field of asbestos regulatory compliance, practitioners have long been literally 'fighting alone.' With no one to consult internally and no knowledge of how other companies are responding, we have strongly felt the need for a space where insights can be shared across company boundaries. The first user meeting marks a major milestone for EMS.

What impressed me most was seeing practitioners from different industries — building management, equipment, and construction — freely exchanging discussions as 'comrades' facing the same legal obligations. The practical knowledge accumulated by each company should rightfully be an industry-wide asset. With the ability to share this knowledge, future regulatory compliance will evolve from 'individual company efforts' to 'collective industry intelligence'.

Asbestos regulations are expected to become even stricter going forward. We at EMS believe that by fostering this kind of community, we can support the entire industry in meeting these growing challenges.
