As of 2023, the share of Japan's psychiatric mental health publications in the world's top 10% cited scientific articles is a key indicator of research impact. From 2024 onwards, a gradual decline is forecasted from 4.41% in 2024 to 4.36% in 2028. This represents a slight decrease with an average annual decline rate, or CAGR, over the forecasted period.

Key future trends to watch include:

Potential shifts in research focus areas that could influence Japan's citation impact.
Collaborations and international partnerships that may bolster the visibility and citation rates of Japanese research.
Emerging technologies and methodologies that could reshape psychiatric mental health research and its impact metrics.
