URGENT UPDATE: A groundbreaking study has just unveiled how train fare subsidies can dramatically increase daily walking steps for prime-aged adults. Conducted by Dr. Haruka Kato from Osaka Metropolitan University and the Sakai City Government, the research highlights a unique approach to combat rising health care costs through increased physical activity.
In a randomized controlled trial involving 900 participants, researchers utilized the HealthSmart-Senboku smartphone application over a period of seven weeks. This innovative program aimed to incentivize walking by offering digital train tickets worth either 2,000 JPY or 1,000 JPY to participants.
The findings reveal that those receiving the 1,000 points subsidy significantly boosted their daily walking by an impressive 711.43 steps per day among prime-aged adults aged 20-49. However, middle-aged (50-64) and older adults (≥65) did not show a significant increase in their walking compared to the control group.
Dr. Kato emphasized the implications of these results, stating, “
These findings suggest that fare subsidy programs that encourage active travel require appropriate pricing. Further, this provides important insights into the effectiveness of train fare subsidy programs for prime-aged adults.
”
As developed countries grapple with escalating health care costs, this research published in Research in Transportation Economics on July 15, 2025, underscores the potential of targeted subsidies to promote a healthier lifestyle.
What happens next? Authorities and policymakers may look to implement similar programs to encourage walking and reduce health care expenditures, especially for younger adults. This study serves as a timely reminder of the need for innovative solutions in public health initiatives.
Stay tuned for more updates as this developing story unfolds.
