Tokyo, Japan-March 25, 2026
Thank you very much for purchasing Yokogawa's products.
We wish to inform you that counterfeit Yokogawa products such as transmitters, controllers, and batteries are being sold by unauthorized suppliers who are not part of Yokogawa's official sales channel. These products, which have been designed and manufactured by unknown parties, have been labeled as Yokogawa products.
Many counterfeit and improperly modified products are significantly different in quality and performance from Yokogawa products and may not function correctly, causing equipment malfunctions, putting a plant's operations, maintenance, security, and safety at risk.
We therefore strongly recommend that you purchase Yokogawa products only from a legitimate Yokogawa supplier. If there is any doubt as to the legitimacy of a supplier, please contact the nearest Yokogawa sales office to confirm this.
Here is a list of Yokogawa sales offices along with the necessary contact information:

Please bear in mind that we are not responsible for any losses or damages from the purchase or use of counterfeit or improperly modified products.
We are taking every measure to address this problem, and thank you for your understanding.
