The forecasted share of scientific publications in psychiatric mental health involving international collaboration in Japan shows a gradual decline from 2024 to 2028, beginning at 11.56% in 2024 and reducing to 10.91% by 2028. As of 2023, this share stood at 11.76%. The year-on-year decreases may appear small, yet they indicate a consistent downtrend with a compound annual growth rate that is negative over this period.

Future trends to watch for might include:

Potential shifts in research priorities within Japan that might affect international collaboration rates.
Global developments in psychiatric research encouraging or discouraging cross-border partnerships.
Policy changes or funding increases targeting international collaboration aimed at reversing the declining trend.
