From late August to early November 2025, at the "Mitsubishi Electric Living and Equipment Solutions Exhibition" held in Tokyo, Nagoya, and Osaka, the Instant Drain Business Promotion Office showcased the Instant Drain-kun 2 and soft starter devices. At the Osaka venue, a demonstration was presented using the actual Instant Drain-kun 2, introducing a method of alternating operation between two units, which particularly attracted 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, when explained that they start and stop slowly through voltage control, many visitors learned about them for the first time, and they received 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 about 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, with heartfelt congratulations from all participants. A group photo was also taken, and the milestone anniversary was celebrated in a warm and grateful atmosphere.

The company brochure has been renewed.
