Agile HR Inc. and Intage Inc. jointly developed and conducted joint research with the University of Tokyo on the "A&I Engagement Standard Survey" national survey. Following the initial and second preliminary reports, this report presents the analysis results by industry. We will thoroughly analyze the structural factors of "Academia, Research, Professional & Technical Services," which has led for two consecutive years, and "Primary Industries," which has advanced to second place. We will also analyze "Medical, Health Care and Welfare," which dropped to ninth place due to the impact of the "2024 Physician Work Style Reform," "Construction and Transportation" struggling with the chronic "2024 Problem," and "Manufacturing," which has ranked last for three consecutive years! 1. Survey Overview and Overall Trends: Engagement Remains Stagnant The fourth (2026 edition) national survey of the "A&I Engagement Standard Survey," jointly developed by Agile HR Inc. and Intage Inc. and conducted in joint research with the University of Tokyo, has been completed. This survey is the largest-scale fixed-point survey of engagement trends in Japan, targeting 10,576 working men and women nationwide aged 15 to 79. The business environment in Japan from 2023 to 2026 was a period where "human capital management" emerged as a central issue determining corporate sustainability, against the backdrop of worsening labor shortages. Companies are being forced to transform their management practices beyond simply reducing working hours to drawing out employees' "vitality" and "enthusiasm" and linking them to results. However, looking at the four-year trend of the overall employee engagement index (average of work engagement and organizational commitment), it shows a plateau (stagnation of improvement) in the high 2.5 range since 2024, with scores of 2.52 in 2023, 2.59 in 2024, 2.55 in 2025, and 2.58 in 2026.
