Battle Against the Invasive Bark Beetle at Sakaitama Kofun Park

On July 7, 2026, a significant event took place at Sakaitama Kofun Park in Gyoda City, Saitama Prefecture. In collaboration with park administrators, Asante Co., Ltd. organized a capture effort targeting the invasive species known as the Kurbiakatuyakamikiri, or invasive bark beetles. This initiative not only aims to reduce the impact of these pests but also emphasizes the importance of community involvement in environmental conservation.

The Invasive Threat

The Kurbiakatuyakamikiri has emerged as a noteworthy threat to local flora, particularly trees in the Rosaceae family such as cherry, plum, and peach. Initially discovered in Aichi Prefecture in 2012, this pest has proliferated across 17 prefectures, including Tokyo and Osaka, damaging numerous trees in Sakaitama Kofun Park. The outbreak has been troubling, especially with a noticeable impact on many cherry and plum trees within the park.

Previously, Asante had conducted inspections and extermination efforts, with activities reported in December 2024 and February 2025. The latest effort in June 2025 included testing the efficacy of the extermination methods used for these invasive pests. During the event, approximately 140 adult beetles were captured after a focused search lasting about four to five hours. The information gathered is crucial as it helps gauge the effectiveness of ongoing pest control measures.

Observations and Community Involvement

During the activity, the team noticed multiple visitors showing interest and inquiring about the ongoing beetle capture. Some locals reported that their neighborhoods were also experiencing pest damage to trees. These conversations suggest a growing awareness of the issue within the community which is vital for mobilizing local support for ongoing conservation initiatives.

The results from this pest control operation revealed both positive and concerning findings. On cherry trees that had previously undergone treatment, no new signs of damage were detected, indicating effective management. However, untreated trees displayed fresh signs of infestation, underscoring the continuous need for vigilant monitoring and intervention in managing these pests. Additionally, damage was noted not only to cherry trees but also to plum trees, emphasizing the expanding threat of the Kurbiakatuyakamikiri.

Collaboration for Effective Solutions

Asante remains committed to collaborating with local authorities and park managers to limit the damage caused by the Kurbiakatuyakamikiri and preserve the unique natural environment of Sakaitama Kofun Park. The significance of these collaborative efforts, as shared by museum staff, highlights the ongoing struggle against these pests and the dedication required to protect local flora.

"The teamwork with Asante was invaluable as it enabled us to capture a large number of beetles in a short time, which was very encouraging," said Mr. Kaneko, a senior official at the Sakaitama Historical Museum. His statement emphasizes the importance of effective partnerships and community engagement to combat invasive species.

Asante's Commitment to Environmental Stewardship

Asante has been at the forefront of building sustainable practices in house maintenance and pest control for over 50 years. Their programs, such as the “Cultural Heritage of Wood” project, underline the importance of preserving Japan's historical wooden structures and natural resources. This initiative shares vital knowledge on pest control while fostering awareness of risks to wooden architecture and local ecosystems.

Through their expertise, as demonstrated during recent beetle capture activities, Asante aims to safeguard the beautiful landscapes cherished by communities while also extending their services to help keep homes safe from various pests. Such activities not only protect individual properties but also contribute to broader environmental health.

In conclusion, the battle against invasive species like the Kurbiakatuyakamikiri requires a collective effort from various stakeholders. By continuing to engage with the community and leveraging expert knowledge, Asante and local authorities are determined to preserve the integrity of Sakaitama Kofun Park and its unique natural environment for future generations.
