What fundraising efforts has Uniqlo partaken in?

Uniqlo has engaged in fundraising efforts primarily through collaborations with non-profits and foundations, which aim to provide support for disaster relief and various community initiatives. This approach underscores the brand's commitment to corporate social responsibility and its recognition of the importance of contributing to society during times of need. By partnering with established organizations, Uniqlo leverages its resources and reach to make a larger impact in communities affected by crises or challenges. These collaborations can include donations, awareness campaigns, and other forms of support that align with the company’s values, showcasing their dedication to social causes.

In contrast, the other answer choices do not accurately reflect Uniqlo's approach to fundraising and community involvement. Investments in stock market ventures or focusing solely on internal fundraising for employee benefits does not encompass the company’s broader social commitments. Supporting only large corporations would contradict their mission of contributing positively to society and helping those who are in need.
