Dear Sir/Madam, I would like to express my congratulations on the continued prosperity of your esteemed company. I sincerely appreciate your exceptional support for our products. Our company has been striving for operational efficiency and rationalization; however, due to the soaring prices of crude oil, naphtha, non-ferrous materials, and foreign exchange fluctuations, it has become difficult to compensate for these challenges through corporate efforts alone. Regrettably, we will be revising the prices of our products as detailed below. We are committed to further cost reduction in the future. In light of these circumstances, we sincerely apologize for the inconvenience, and we kindly ask for your understanding and cooperation, taking into consideration the various factors at play. Sincerely, [Target Products] All HS valves [Revision Rate] Approximately 10% for resin valves, 20% for brass valves [Effective Date] From shipments on October 1, 2025 For further details, please contact our sales representative. Thank you for your understanding.

From late August to early November 2025, at the "Mitsubishi Electric Living and Equipment Solutions Exhibition" held in Tokyo, Nagoya, and Osaka, the Immediate Drain Business Promotion Office showcased the Immediate Drain-kun 2 and soft starter devices. At the Osaka venue, a method of alternating operation using the actual Immediate Drain-kun 2 was introduced, particularly attracting visitors' interest with the automatic switching of the starting pump via a timer. Additionally, regarding the soft starter devices, although they are often misunderstood as inverters due to their name, the explanation of their characteristics—starting slowly and stopping slowly through voltage control—was new to many visitors, receiving positive feedback.

In 2025, Hashimoto Environmental Equipment Trading (Shanghai) Co., Ltd. celebrated its 30th anniversary with a commemorative event held at its office in Pudong, Shanghai. The company has approximately 10 employees who are primarily engaged in quality control of ODM products and trade operations. On that day, we received numerous floral tributes from our business partners, and stories were shared about the early days of the company, challenges faced, and fond memories, accompanied by heartfelt congratulatory messages from all attendees. A group photo was also taken, and the milestone anniversary was celebrated in a warm and grateful atmosphere.
