Mapping the Missing Green: An AI Framework Boosts Urban Greening in Tokyo
2025.10.30
Research
As cities grow denser and hotter, creating space for greenery becomes increasingly difficult. To address this challenge, researchers from Chiba University developed a data-driven framework that integrates artificial intelligence and spatial analysis to map vertical greenery across Tokyo’s 23 wards. By analyzing over 80,000 street-view images, the team identified uneven distribution patterns and proposed a vertical greening demand index to guide future urban greening initiatives and climate-resilient urban planning.

Researchers from Chiba University analyzed over 80,000 street-view images to map vertical greenery in Tokyo, revealing that green façades are much more prevalent than living walls. The study also identified areas where additional greenery could improve urban comfort, mitigate heat, and enhance overall city life.
