On May 13, GIANTY Vietnam (Ho Chi Minh City; wholly-owned subsidiary of GIANTY Inc., Japan; hereinafter referred to as “GIANTY”) signed a Strategic Partnership Memorandum of Understanding (MOU) with KIDS STAR Vietnam (Ho Chi Minh City; wholly-owned subsidiary of Kids Star Inc., Japan; hereinafter referred to as “Kids Star”) to accelerate the business development of “Gokko World” in Vietnam.
Through this partnership, both parties will work together to expand the merchant base on “Gokko World” and co-produce localized digital content.

This partnership reinforces Kids Star Vietnam’s deep localization strategy, combining Japanese content expertise with local market knowledge to position “Gokko World” as a trusted digital learning platform across the region.
