Booost Inc. (Shinagawa-ku, Tokyo; Representative Director: Hironori Aoi; hereinafter, "the Company"), which supports corporate SX (Sustainability Transformation)*3 through the provision of "Sustainability ERP*1" with the No. 1* share among major companies and the advocacy of the "Sustainability 2026 Problem*2," announces that the number of members of the "Sustainability Leadership Community (hereinafter, SLC)" organized by the Company has exceeded 1,000 as of the end of March 2026.
In conjunction with this, a survey of practitioners was conducted regarding compliance with SSBJ standards, which will become fully operational from the fiscal year ending March 2027, revealing key challenges in disclosure compliance for Japanese companies. We will also begin recruiting for the second term of the "SSBJ Subcommittee," a program for practitioners that supports the resolution of these challenges.
Furthermore, to commemorate surpassing 1,000 members, we have launched the "Have Your Say Expert Series," a dialogue and contribution project by experts, on the online media "Sustainability Leadership Magazine (hereinafter, SLM)." Today, as the first installment, an interview article and video featuring Mr. Masaaki Anma, Secretary-General of the Impact-Oriented Finance Declaration, and our COO Taiga, have been released. We will continue to disseminate practical insights that lead to enhanced corporate value, not just compliance with regulations.
■ What is the Sustainability Leadership Community (SLC)?
SLC is a free, registration-based community for practitioners and experts from companies working on sustainability promotion, based on the concept of "Sustainability Together." Since its launch in 2023, practitioners from diverse departments such as sustainability, corporate planning, IR, and finance have participated, sharing knowledge on SX promotion and information disclosure.
SLC provides a platform for companies to bring their challenges together and implement them in practice through large-scale conferences and small-group "SSBJ Subcommittees." In the subcommittees, cases have emerged that lead not only to understanding the system but also to building internal systems and launching projects.
In September 2025, we also launched the online media "Sustainability Leadership Magazine (SLM)," which disseminates explanations of regulatory trends and knowledge directly applicable to practice. As a result, SLC, as a community equipped with both a "place for dialogue and practice" and a "foundation for information and knowledge," connects companies' sustainability efforts from "knowing" to "acting" through both offline and online channels.
As of the end of March 2026, the number of members has exceeded 1,000, and it continues to expand as a practitioner network supporting the promotion of SX in Japanese companies.
Number of members: 1006 people / Number of member companies/organizations: 701 companies (as of April 1, 2026)
Among the participating companies, 34 companies have a market capitalization exceeding 3 trillion yen. This indicates that approximately half of the "3 trillion yen companies," of which there are only about 70* in the Japanese market, are participating in SLC, making it a community where practical leaders of companies driving the Japanese economy gather.
*Based on market data as of March 2026
■ Current Status of Corporate Disclosure Compliance (Original Survey)
With the full-scale implementation of sustainability information disclosure based on SSBJ standards scheduled from the fiscal year ending March 2027, our independent survey* revealed that Japanese companies' responses are still in the initial stages. Approximately 70% of companies remain in the "not yet started to information gathering stage" for SSBJ compliance.
*Integrated analysis of 7 seminar questionnaires (n=544) conducted from July 2025 to February 2026.
The main challenges faced by companies are as follows:
・ Development of promotion system and inter-departmental collaboration
・ Data preparation
・ Determination of policy and scope
In particular, bottlenecks are evident in both organizational structure and data infrastructure.
・ More than 40% have not yet started building a system
・ Approximately half have not yet prepared data
Furthermore, only about 20% of companies position sustainability initiatives as a management agenda linked to enhancing corporate value. This result highlights the reality that sustainability initiatives are still not driven by management and are being pursued within a limited scope by many companies.
■ Future Plans
SLC will strengthen its efforts to enable practitioners to "actually take action" on the issues identified in the survey. By combining online and offline approaches, we will not only share regulatory trends but also promote the accumulation of knowledge and the formation of practical networks related to sustainability promotion through sharing corporate case studies and discussing practical challenges. Recent key initiatives are as follows:
➀ Offline: SSBJ Subcommittee Second Term
This is a practical program aimed at connecting SSBJ compliance not just to "disclosure compliance" but also to financial impact and management decisions. Ahead of the full application from the fiscal year ending March 2027, companies' responses are polarizing into either "minimum disclosure" or "advancement to include financial impact." Investors are strongly demanding explanations that consider financial impact and connections to management. This subcommittee aims to achieve the latter, supporting practical responses that lead to enhanced corporate value through a total of six sessions. We encourage your participation.
Period: June 2026 - November 2026
Date & Time: Once a month (total 6 sessions) 16:00 - 18:00 each session
Format: In-person (meeting room in Tokyo)
Capacity: Up to 16 companies (small group)
Target: Practical leaders responsible for SSBJ compliance at listed companies with a market capitalization of 500 billion yen or more
- Practical discussions in a closed environment limited to listed companies and small groups
- Issue design based on practical challenges, not just system explanations
- Cross-cutting discussions on materiality, financial impact, and governance
- Organization of issues in a way that leads to management decisions
- "I gained insights that apply to sustainability as a whole, not just system compliance."
- "I understood the importance of financial impact and promoted cross-departmental collaboration."
- "Through discussions with other companies, my understanding and organization of issues related to SSBJ compliance deepened."
- "The network for sharing progress and concerns with other companies was of great value."
- "I reconfirmed that materiality identification is the starting point for everything in financial impact assessment, indicator setting, and disclosure story building."
② Online: Enhancement of Rich Content for Members
To commemorate surpassing 1,000 members, Sustainability Leadership Magazine (SLM) has launched the special project "Have Your Say Expert Series" by experts. In this series, we will multi-dimensionally explain issues surrounding sustainability management and information disclosure from the perspective of experts involved in international rule-making and the forefront of practice, through dialogues and contributions, and disseminate practical insights that lead to enhanced corporate value, not just compliance with regulations.
Today, as the first installment, an interview article and video featuring Mr. Masaaki Anma, Secretary-General of the Impact-Oriented Finance Declaration, and our COO Taiga, have been released.

We look forward to the participation of those aiming to advance sustainability management.

■ Project "Making Japan an SX Advanced Nation" Aiming to Solve the Sustainability 2026 Problem
Currently, many companies are facing the "Sustainability 2026 Problem," a situation where delays in starting and a lack of urgency regarding the mandatory disclosure of sustainability-related financial information raise concerns about a potential decline in corporate value. To overcome this problem and enhance Japan's global presence through SX promotion and corporate value improvement, the Company launched the "Making Japan an SX Advanced Nation" project in November 2024.
This project simultaneously deploys events and support measures for both on-site practitioners and management (executives).
