Hello, this is Arihiro Kodaka, and I am in charge of Engineering Design II for 2nd year students. At ICT, we place great importance on practical learning in collaboration with the local community. In Engineering Design II, students tackle agricultural challenges faced by the region and explore solutions from both technological and business perspectives. The Tech Team provides technical support for wildlife damage prevention to protect sweet potatoes, while the Business Team works to revitalize the community by marketing the protected sweet potatoes as a local brand product.

 In this class, students are expected to accurately understand the current situation, identify new approaches to revitalizing the local community, and establish clear design objectives to realize those ideas. To achieve this, it is essential for them to gain a multifaceted understanding of the significance and impact of cultivating crops in this region, as well as the resources and effort required. As a first step, the entire class participated in creating ridges in the field, planting sweet potatoes, and installing electric fences to prevent wildlife damage.

Please also refer to the Hakusanroku Journal written by President Maasaki Shikada, “2nd Year Engineering Design: Beniharuka Sweet Potato Planting (May 26th, 2025)"

 Although it was already mid-April this year, more than 50cm of snow remained in the field, and the temperatures were still low, making it difficult to plant the seedlings. However, thanks to a miraculous period of continuous rain, the snow melted just in time for the scheduled delivery of the seedlings, allowing us to proceed with planting. However, the temperatures this spring were in the low 10℃, which was quite cold and not ideal for root development or growth. The seedlings didn’t look very healthy, and I was worried. Fortunately, in May, the temperatures finally started to rise, and I was relieved to see the seedlings beginning to grow.
 Even after the seedlings had taken root, we continued to monitor their condition. This year, I noticed that some seedlings had been pulled out. Upon researching online, we found reports indicating that newly planted seedlings can be an easy target for crows, which may be what happened in our field as well. Additionally, we observed that the electric fence had become loose due to the wire mesh getting caught on the binding wire used to secure it to the poles. Next year, we plan to install a camera to closely monitor what happens in the field after planting. We will be selling sweet potatoes again this year, so please enjoy our exceptionally sweet Kosen Beniharuka!
