In 2023, Japan's nervous system medicine sales were expected to account for 10.6% of total sales. The forecasts from 2024 onwards show a gradual increase to 10.7% by 2025, maintaining this percentage through to 2028. This indicates a relatively stable market share for nervous system medicines over the five-year forecast period.

Future trends to watch for include:

The potential impact of technological advancements and new drug developments on market share.
Healthcare policy changes in Japan that might affect nervous system medicine demand.
Demographic shifts, particularly an aging population, which could drive increased consumption of nervous system medicines.
