(Headquarters: Shinjuku-ku, Tokyo; Representative Director: Yuichi Kamino; Securities Code: 4293), in collaboration with Plan International Japan (Location: Setagaya-ku, Tokyo; Chairperson: Kiyoko Ikegami; hereinafter "Plan"), a public interest incorporated foundation, will hold a free webinar for corporate public relations, sustainability, CSR/ESG/DEI personnel titled "How to Connect Social Contribution to Brand Value, Recruitment, and Employee Engagement?" on Friday, June 19, 2026.

■ The Growing Importance of Sustainability in Corporate Management and the Evolving Approach to Social Issues

Currently, corporate SDGs and sustainability activities are expected to go beyond mere donations and financial support, connecting to corporate value through brand building, employee engagement, DE&I, human capital management, and building relationships with the next generation.

In particular, "support for women's empowerment and gender equality" is gaining attention as a key theme for companies in Japan, which has the largest gender gap among G7 countries and globally (Note 1).

Therefore, Plan, which conducts various activities annually around the International Day of the Girl (October 11) (Note 2) and will launch the "Plan Girls Movement 2026 Jibun Rashisa Kenkyujo" (Self-Identity Research Institute) in 2026 to create a space where young women can discover their individuality and express themselves safely, together with companies, and gooddo, which supports many companies in planning and co-creating CSR and sustainability activities, have partnered to hold this webinar.

On the day, gooddo will introduce recent changes surrounding sustainability activities. Additionally, Mirei Koizumi, a former CMO at a foreign-affiliated company and currently CMO and Head of the Marketing & Communications Department at Plan, will take the stage. Starting from the International Day of the Girl, she will explain the significance of companies working on gender equality, how to transform social contribution into an impact on brand value, recruitment, and internal penetration, and provide specific practical tips.

Furthermore, as an action companies can take towards the International Day of the Girl, information on how to participate as a partner in the "Plan Girls Movement 2026" will be provided.

Note 1: Quoted from the Nippon Foundation's "18-Year-Old Awareness Survey '62nd – Awareness of Country and Society (6-Country Survey)' Report" p.4

Note 2: A day designated by the United Nations to call on the international community to promote the "rights of girls" and "empowerment of girls."
