Company Overview
DFree Inc., formerly known as Triple W Japan Inc., is a Japanese health-tech company that develops and sells 'DFree,' a wearable device for urinary incontinence. Founded in 2015 by Atsushi Nakanishi, the company aims to improve the quality of life for individuals, particularly seniors and people with disabilities, by providing a non-invasive solution to manage bladder control. The DFree device uses ultrasound technology to monitor bladder fullness and sends notifications to a smartphone or tablet, predicting the right time to go to the bathroom. This helps users gain independence and reduces the burden on caregivers. The company has offices in Tokyo, Japan, and San Diego, USA, and its products are used in numerous senior care facilities.
