Market overview

Parkinson disease is a degenerative disorder of the nervous system that impacts a person ability to move. It develops when nerve cells in the substantia nigra are impaired or lost, leading to a drop in dopamine levels an essential neurotransmitter for regulating smooth and coordinated muscle activity. Typical symptoms include shaking, muscle rigidity, slowed movements (bradykinesia), and issues with balance and coordination. As the condition progresses, it may also influence speech, facial expression, and various non-motor functions such as sleep patterns, mood, and cognitive abilities. Japan’s Parkinson’s disease market is shaped by an aging population, sustained reliance on levodopa therapies, growing demand for add-on treatments to address motor fluctuations, rising adoption of DBS, advancing leadership in iPSC-based regenerative medicine, and high healthcare accessibility that supports steady treatment uptake. The Parkinson’s disease landscape in Japan is characterized by personalized treatment strategies, enhanced attention to non-motor symptoms, integration of wearable and remote monitoring technologies, active participation in clinical studies, and initiatives to improve early detection.

Parkinsons patients in Japan receive substantial financial support through the national health and long-term care insurance systems, and the government actively fosters R&D for novel therapies, such as stem cell treatments, to enable their inclusion in insurance coverage.
