From August 1 (Friday) to August 3 (Sunday), 2025, at the "2025 FIM World Endurance Championship 'Coca-Cola' Suzuka 8-Hour Endurance Road Race 46th Edition," Suzuki Motor Corporation's Motorcycle Business Division has introduced our online shop's exclusive product, the "AQplus Hybrid Blower AQR-18HB Series," in collaboration within the SUZUKI team. It has been utilized in the pit during test runs and the actual race. We have also received feedback from the operators. "This time was a test session, so we used it for air conditioning in the pit. It was placed in a larger size where we listen to rider comments after the run. For the actual 8-hour race, we plan to place it in front of the riders sitting in the starting area. Regarding its use, since it is battery-operated, it can be placed anywhere in the pit without restriction, and the operating noise is quiet, so it does not hinder the voices of other staff, while still providing sufficient airflow, making it very convenient. I believe it will be used as air conditioning in the pit during the main event as well." The product is available for purchase at our online shop, so please check it out.

Recently, our company issued an SDGs private placement bond through Shiga Bank and donated "one wooden bookshelf, eleven books, and seven educational toys" to the Hikone Welfare Association's "Takeshi Nursery." The SDGs private placement bond aims to contribute to solving local community issues through collaboration between banks and companies. A portion of the fees received by the bank from the companies that issue the private placement bonds is used to purchase goods, which are then donated to organizations engaged in SDGs initiatives, with the donating company able to choose the recipient. (Details are available on Shiga Bank's website.) The staff at Takeshi Nursery were very pleased, and all of our employees are also very happy! As a company that contributes to the community for regional development, we are committed to social contribution activities related to the SDGs and promote CSR activities.

We have entered the "Health Action Declaration" conducted by the Shiga Branch of the National Health Insurance Association. To better serve our clients and contribute to the community, we will actively engage in initiatives that consider the workplace environment and employee health, aiming to improve productivity.
