In 2023, the share of corresponding/leading authors in Japanese scientific publications on pollution was at an estimated base value. The forecasted data from 2024 to 2028 indicates a subtle but consistent decline in this share, with values gradually decreasing from 89.59% in 2024 to 88.39% by 2028. This represents an approximate year-on-year variation of around 0.3%, suggesting a slight decrease in the dominance of corresponding authorship roles over this period.

Future trends to watch for include:

Shifts in collaboration dynamics, possibly due to increased interdisciplinary research.
Influence of international partnerships on authorship patterns.
Changes in publication practices as Japan adapts to new scientific challenges and technologies.
Potential impact of open science and data sharing initiatives on authorship roles.
