The share of corresponding/leading authors in scientific publications on complementary and alternative medicine in Japan is expected to gradually decline over the next five years, starting at 93.26% in 2024 and decreasing to 92.85% by 2028. Compared to 2023, the forecast indicates a slow but steady reduction in this share, with an average annual decrease—CAGR—pointing to a minor yet consistent downtrend.

Future trends to watch for:

Potential shifts in collaboration practices that might further affect the authorship share.
Increasing influence of international contributors, possibly leading to diversified authorship in publications.
Changes in publishing norms or policies that might redirect the authorship dynamics in the field.
