TOASU to Change Company Name to Gakken Business Brains on July 1, 2026

Gakken Co., Ltd. (Tokyo, Shinagawa / President and Representative Director: Hiroaki Miyahara) group company, TOASU Co., Ltd. (Tokyo, Shinagawa / President and Representative Director: Akira Miyata), will change its company name to "Gakken Business Brains" (English notation: Gakken Business Brains Co., Ltd. / common name: Gakken BB) on July 1, 2026.

This change is in conjunction with the launch of the new service brand "Gakken Business" announced on May 27. This brand will initially be rolled out with our company's solutions at its core. Under the new company name, we will further strengthen our role as a "partner that runs alongside" clients, embodying problem-solving directly in their operational environments.

■ Background of the Company Name Change

As the management challenges faced by companies become increasingly complex, it is difficult to envision sustainable growth by merely addressing immediate issues based on the current situation. To support the transformation of companies and individuals by working backward from their desired future state, rather than starting from the past or present, we announced the launch of "Gakken Business," a new service brand for the corporate and business professional domain, on May 27.

This company name change is the first step in more clearly demonstrating to society our stance and raison d'être as a "problem-solving partner" that embodies the promise of this new brand to accompany clients' "will to move forward" and to support them until their goals are achieved.

■ Our Unchanging Core: Problem-Solving Partner

While the company name and the value proposition of the brand will expand, our central focus on "solving clients' human resource and organizational challenges" remains unchanged.

As before, we will continue to be a partner that accompanies clients towards their desired goals, rather than merely a vendor providing standardized programs.

We will comprehensively handle everything from the planning and development of solutions offered by "Gakken Business" to their actual service delivery, becoming the wisdom that supports your strategies and the driving force that moves operations, directly supporting the transformation of human resources and organizations.

■ Meaning Behind the New Company Name

The word "Brains" following "Business" in our business domain carries a meaning beyond mere intelligence or intellect.

We aim to be a partner that earns even greater trust and is consulted more frequently by clients, driven by their "will to do" and "what they should do," by pooling our wisdom together to contribute to problem-solving. We will strive to become a trusted "partner that accompanies clients until their goals are achieved."
