Kickoff Tree Planting Event in Yokosuka Promotes Diversity and Sustainability

On April 6, 2025, a remarkable tree-planting event took place at the Shonan International Village in Yokosuka, Kanagawa Prefecture, organized by the certified NPO, Environmental Relations Institute (ERI). Under the leadership of Atsuko Suzuki, the organization kicked off its 'Present Tree' project, a significant initiative aimed at forest regeneration and the promotion of biodiversity.

Despite the unfortunate rainy weather on the day of the event, the spirit of community and collaboration filled the air. A diverse group of 52 supporters of the Present Tree project, local partners from the Silva Association, members of the 'Donguri Brothers,' a welfare facility team dedicated to forest creation, and local government representatives participated in the tree-planting venture. Attendees of all ages came together to plant 1,000 deciduous trees comprising 35 different species using the innovative 'mixed plantation and dense planting method,' a technique developed by renowned ecologist Akira Miyawaki. This method promotes the restoration of forest ecosystems that resemble native forests by planting multiple species closely together, fostering competition among plants to accelerate forest growth.

Typically, it takes 200 to 300 years for a natural forest to develop, but with this method, it is possible to achieve a similar outcome in just 20 to 30 years. Participants received guidance from tree-planting leaders before getting their hands dirty and starting the planting process. Looking at the forest planted 14 years earlier was a poignant reminder of progress, offering all involved a chance to witness the impact of their efforts.

Community Voices

After the event, participants shared their reflections. Many expressed their amazement at witnessing the growth of trees previously planted. Some commented on the enlightening experience of understanding how tree planting works in practice, while others noted the unique approach taken this time compared to previous experiences.

One participant joyfully stated, “Children actively engaged in the activities, and we were pleasantly surprised by how immersive the planting experience was.” Another remarked on the emotional resonance of hearing from those supporting the tree-planting initiative, deepening everyone’s understanding of its importance and purpose.

A sense of appreciation for the long-term commitment to ecosystem-friendly planting methods resonated among participants. “I hope this initiative gets communicated to even more people,” expressed another participant, highlighting the desire for greater awareness.
