Craif | Realization of a society where people achieve longevity
Using Craif's proprietary technology, we detect cancer-specific signals via AI from microRNAs—molecules that play an important role in the onset and progression of cancer. This technology powers our urine-based cancer risk test, miSignal Scan*, which enables early detection of cancer risk even before symptoms appear. We are also advancing the development of a medical device in both Japan and the United States, offering a new option to support the early detection and accurate diagnosis of pancreatic cancer. *Available only in Japan


Currently available only in Japan.
Through our proprietary biomarker analysis platform NANO IP® (NANO Intelligence Platform®)—which decodes a wide range of biological signals such as DNA and RNA found in body fluids like urine—and by combining it with advanced AI algorithms, Craif is pioneering a Bio-AI approach.
This integrated technology enables us to develop next-generation diagnostic tests and medical devices aimed at the early detection of diseases such as cancer, as well as the realization of personalized treatment tailored to each individual.
