Yamanashi Prefecture (Governor Kōtarō Nagasaki) held a "Joint Declaration Ceremony for Sustainable Economic Development and Improvement of Wage Levels" in Kōfu City on June 23. The backdrop to this initiative is the deepening outflow of young people from the prefecture and a shortage of workers, amidst ongoing soaring prices and labor shortages. A survey in Reiwa 7 (2025) revealed that the U-turn employment rate for students who advanced to universities outside the prefecture was 21.8%, the lowest in 13 years, and the number of people aged 20-24 moving out of the prefecture reached 1,480. In light of these circumstances, the prefecture has positioned wage level improvement not merely as an issue between labor and management, but as a critical challenge related to the sustainability of the regional economy, demonstrating a commitment to collaboration among businesses, workers, administration, and related organizations. A total of 39 organizations participated in the joint declaration, including the Yamanashi Employers' Association, the Yamanashi Chamber of Commerce and Industry Federation, the Yamanashi Federation of Small and Medium Business Associations, the Yamanashi Prefectural Central Association of Small and Medium Enterprise Organizations, local financial institutions, Rengo Yamanashi, all municipalities within the prefecture, the Yamanashi Labor Bureau, and Yamanashi Prefecture. At the ceremony, attended by approximately 100 people including representatives from labor-management organizations and administration, Governor Kōtarō Nagasaki pointed out that the stagnation of real wages is affecting people's sense of well-being and their anxieties about the future, amid an uncertain economic outlook due to soaring prices and international instability. He then appealed for the need for businesses, workers, and the administration to unite as "one team" and work towards a sustainable increase in wage levels to realize a "society where hard work is rewarded."
