Exploring the Impact of Urban Green Spaces on Well-being

Tokyo's Otemachi Tower has recently become the centerpiece of an innovative study aimed at scientifically verifying the effects of urban green spaces on well-being. A collaborative effort between Tokyo Building Co., Ltd. and the Forestry and Forest Products Research Institute marks this groundbreaking venture, focusing on the lush landscape known as "Otemachi Forest." This urban oasis not only beautifies the city but also serves as a vital environment for enhancing the health of its workers and visitors.

What is Otemachi Forest?

Spread over approximately 3,600 square meters, Otemachi Forest constitutes one-third of the Otemachi Tower premises, a mixed-use development that includes office spaces, hotels, and commercial facilities, completed in 2014. Since its establishment, this majestic urban forest has been managed to closely resemble a natural forest, providing local workers and visitors a serene refuge from the bustling city life.

The Research Initiative

The research initiative targets 30 workers from the Otemachi area, utilizing vital measurements such as stress hormone levels and sympathetic nervous system activity, coupled with psychological assessments through surveys. The team aims to analyze how spending time in Otemachi Forest positively impacts both physical and mental health. Additionally, the study will quantify and visualize the multifaceted benefits of urban green spaces, particularly its potential to mitigate the urban heat island effect, a pressing concern in modern city landscapes.

Research Implementation Details

• - Duration: The study is set to run from August 2025 to the end of March 2026.
• - Focus Areas: 1) Evaluating the impact of Otemachi Forest on well-being through various physiological and psychological metrics. 2) Measuring the thermal conditions within the forest using relevant environmental indicators.
• - Location: The study takes place within Otemachi Tower's grounds, situated in Chiyoda, Tokyo, at 1-5-5 Otemachi.
• - Collaborators: In addition to Tokyo Building and the Forestry Research Institute, organizations such as the Green Infrastructure Research Association and Toho Leo Co. are supporting the initiative.

Benefits of Urban Green Spaces

Research like this is vital as evidence accumulates around the benefits of urban green spaces for mental health and overall well-being. Otemachi Forest offers more than aesthetic appeal; studies suggest proximity to natural environments can reduce stress, improve mood, and enhance productivity.

In terms of environmental benefits, Otemachi Forest has successfully decreased the temperature around high-rise buildings in the area by an average of 1.7 degrees Celsius, providing an essential respite from heat and contributing to the broader ecological network surrounding the Imperial Palace and its gardens. Furthermore, this urban forest has proactively managed water resources by employing methods to temporarily store rainwater, protecting the area from flooding during heavy rains.

Ecological Notables at Otemachi Forest

Since its establishment, Otemachi Forest has seen a significant increase in plant biodiversity. From 107 species at launch to around 208 species, including rare flora listed on national and Tokyo’s red lists, the forest has become a haven for various wildlife. Notably, the landscape supports numerous insect species, such as the Ulana Apache butterfly, and bird species like hawks and falcons, indicating a thriving ecosystem.

Reimagining Urban Spaces

Otemachi Forest stands as an example of thoughtful urban planning that harmonizes nature with city life. With ongoing events aimed at educating visitors about biodiversity and urban ecology, Tokyo Building emphasizes the importance of green spaces in urban settings.

As researchers continue to gather data, findings from Otemachi Forest could pave the way for similar initiatives across urban landscapes, enriching lives and environments alike. This project exemplifies how melding nature into urban design can promote a healthier lifestyle while conserving biodiversity in city settings.
