Innovative Research on Indoor Plants Published in Building and Environment Journal

Pasona Japan, a prominent human resources company based in Osaka, has recently made strides in enhancing indoor environments through research published in the esteemed journal, Building and Environment. This research was conducted in partnership with the Toyota Central R&D Laboratories and the Toyota Motor Corporation Future Creation Center.

The published paper, titled "Subjective Mapping of Indoor Plants Based on Leaf Shape Measurements to Select Suitable Plants for Indoor Landscapes", focuses on the implications of biophilic design to foster well-being. The collaborative project began in May 2019, aiming to create spaces that promote mental and physical health. This innovative research seeks to scientifically explore how indoor plant designs and selection can positively affect the human experience.

The findings from their research demonstrate significant insights into how various leaf shapes of indoor plants impact emotions and ambiance. The study assessed 40 different indoor plants, correlating their physical leaf characteristics with subjective perceptions of relaxation and well-being among participants. Results gleaned from surveys—including both general public and expert opinions—indicate that plants with smaller leaves tend to foster a more relaxing environment. This highlights the importance of thoughtful plant selection in interior design, especially in spaces aimed at enhancing employee well-being.

In 2024, a collective patent concerning a plant classification system based on leaf shape and its potential benefits for indoor spaces was secured. This system enables designers and environmental architects to choose plants that not only beautify spaces but also contribute to mental health.

The journal Building and Environment is recognized worldwide for its rigorous standards in publishing original research in architecture, urban physics, and the interaction between humans and both indoor and outdoor artificial environments. Its focus on innovative technologies and knowledge validated through meticulous measurement and analysis ensures that only the most scientifically robust contributions are shared with the global research community.

Pasona Japan continues to strengthen its collaboration with Toyota's research centers, committing to evidence-based studies that aim to realize a well-being society. As part of their initiative, they have introduced the concept of "COMORE BIZ"—a framework that aims to bring workplace environments closer to natural settings, thus benefiting both employees and companies alike. This sustainable approach integrates the theory of biophilia, encouraging enhanced health management through naturally inspired design elements in workplaces.

In conclusion, the publication of this research is a testament to the interdisciplinary collaboration between Pasona Japan and Toyota, contributing valuable insights into how we might design healthier, more sustainable indoor conditions for individuals. The ongoing commitment to merging scientific exploration with practical application serves as a beacon for future efforts in creating environments that prioritize human well-being.
