On July 2, 2026, researchers from Osaka Metropolitan University revealed that the opening of the Ibaraki City Cultural and Childcare Complex, known as ONIKURU, significantly increased the number of residents lingering in nearby urban areas. This multifaceted facility combines a library, civic hall, childcare support center, planetarium, and community activity spaces, designed by acclaimed architect Toyo Ito.
Impact of ONIKURU on Urban Stay Behavior
The findings, published in the journal Cities, indicate that residents who visited ONIKURU stayed approximately 0.471 more times per week in the suburban city center compared to a matched control group over a six-week period following the facility's opening. This suggests that the multifunctional facility has successfully attracted more visitors to the area.
Using high-resolution GPS trajectory data from smartphone users, the research team analyzed changes in stay locations across the city. The results revealed an increase in stay density near ONIKURU and adjacent commercial areas while simultaneously showing a decrease in stay density around JR Ibaraki Station, indicating a spatial redistribution of urban activity.
Spatial Redistribution of Urban Activity
The study highlights a selective catalytic effect of urban design, where the opening of ONIKURU did not uniformly increase activity across the district. Instead, it redirected urban engagement, confirming the potential of strategically placed facilities to rejuvenate declining suburban centers.
Dr. Haruka Kato, an associate professor involved in the study, stated, "Walkable urban design initiatives are being implemented worldwide, but methods for rigorously evaluating their effects have not yet been established. By leveraging smartphone-based GPS big data, this study demonstrates that it is now possible to measure the impact of walkable urban design at the building scale, something that was previously considered extremely difficult."
Future of Urban Planning in Japan
The implications of this research extend beyond the findings related to ONIKURU. Urban planners in Japan and globally may consider the results as evidence supporting the integration of multifunctional facilities into community designs. As suburban centers face decline in favor of car-oriented shopping malls, such initiatives could play a crucial role in revitalizing urban spaces.
