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.
