CyberStep Holdings and Cocolo Tsunagu Establish New Joint Venture Specializing in Disaster Preparedness Product Subscription and Management Services

CyberStep Holdings Corporation (Head office: Suginami-ku, Tokyo; Representative Director and President: Shinji Yuasa; TSE Standard: 3810; hereinafter referred to as "the Company") will establish a joint venture company, "Cocolo Tsunagu Inc." (our investment ratio 67%), specializing in disaster preparedness product subscription and stockpiling management services, through a joint investment with Cocolo Tsunagu Inc. (Shibuya-ku, Tokyo; Representative Director: Yosuke Ikeuchi; hereinafter referred to as "current Cocolo Tsunagu Inc.", scheduled to change its trade name to CTG Inc. in May 2026), in May 2026.

■ Purpose of establishing the joint venture company
The Company Group has primarily developed and operated online games, expanding its entertainment-related businesses. Moving forward, in addition to developing existing businesses, we aim to explore new revenue streams and further enhance the value of the corporate group. Therefore, we will establish a joint venture company specializing in the provision of disaster preparedness product subscriptions and related management services.

■ Current state and challenges of the disaster preparedness market
In recent years, natural disasters such as earthquakes, typhoons, and heavy rains have frequently occurred in various parts of the country, leading to a rapid increase in the need for stockpiling disaster preparedness products among individuals, corporations, and local governments. However, managing the expiration dates of stockpiled disaster preparedness products, periodic inspections, and establishing a renewal system are challenges, and a state of "prepared but not managed" is widespread. This business aims to solve this social issue through subscription × digital management.

■ Expertise and achievements of current Cocolo Tsunagu Inc.
Although current Cocolo Tsunagu Inc. is a newly established company, all founding members are disaster preparedness specialists with qualifications as "Disaster Preparedness Specialists" and "Stockpile Management Specialists." In addition, some related members have over 10 years of experience in renewable energy-related businesses and have repeatedly discussed the role of renewable energy as an emergency power source with numerous local governments. Through this process, they have accumulated deep on-site knowledge regarding the challenges of disaster preparedness services in local governments.

Furthermore, its representative, Yosuke Ikeuchi, has been involved in system development for many years, making it a unique specialized company that combines on-site knowledge of disaster preparedness and system development capabilities. Leveraging this strength, the basic plan design for disaster preparedness product subscriptions has already been completed, and test provision has begun. Additional options are being organized based on feedback from test results, and the service is ready for immediate launch within the framework of the basic package and existing additional options.

■ Development of original products in collaboration with Tokyo University of Science
To further strengthen competitiveness, we are proceeding with the development of original disaster preparedness products supervised by Professor Takahashi's laboratory at Tokyo University of Science. Professor Takahashi, manufacturers, and current Cocolo Tsunagu Inc. are working together as a tripartite team to promote product development. The plan is to evolve from subscriptions combining existing products to higher-value services incorporating original products.
