4D Inc. (Headquarters: Minato-ku, Tokyo, Representative Director: Ryo Taguchi, hereinafter "4D") has signed a Memorandum of Understanding (MOU) for collaboration with the National Institute of Technology, Tokuyama College (hereinafter "Tokuyama NIT") under the National Institute of Technology Organization. In addition, an educational program for service design was conducted at Tokuyama NIT for three days from June 5 (Fri) to June 7 (Sun), 2026. ■ Background of the Workshop Implementation 4D has been developing service design educational programs, mainly in Southeast Asia, and has accumulated collaboration achievements with multiple universities in Thailand. In February 2026, 4D provided a workshop for joint Japanese-Thai training at "KOSEN-KMITL," a national college of technology in Thailand, with four students from Tokuyama NIT participating (Reference: https://www.4digit.com/topics/260415). Teachers from Tokuyama NIT, who observed the students' engagement in this workshop, requested "to implement a similar workshop at our college as an opportunity to learn design thinking in English." This request became the catalyst for the implementation of the workshop at Tokuyama NIT and the signing of the MOU. Students who completed the training in Thailand participated as facilitators, playing a role in passing on the baton of learning. Tokuyama NIT is focusing on STEAM subjects such as "Problem Discovery Project" for first and second-year students, and international exchange, aiming to foster engineers who can play an active role globally in the coming era. ■ Workshop Overview In addition to 4D members, three participants from the joint Japanese-Thai training at KOSEN-KMITL joined as facilitators for this workshop. A total of 25 people participated, including 12 students (2nd to 5th year) and 7 faculty members. Using "Elderly Care" as the challenge theme, a series of service design workshops were practiced over three days, including persona setting, customer journey map cre
