In 2023, Japan had an impressive number of scientific publications in the world's top 10% cited in chemical engineering. Forecasts suggest a year-on-year decline from 2024 to 2028, with a notable decrease in output. Between 2024 and 2025, the number drops by approximately 6%, followed by further declines of around 6% each year thereafter.

Over the five-year period ending in 2028, the Compound Annual Growth Rate (CAGR) indicates an average annual reduction, reflective of a challenging trend for Japan in maintaining its influential research position in this field.

Future trends to monitor include:

Japan's investment in research and development to counter decreasing global influence.
Collaborations and partnerships with international institutions to enhance citation impact.
Aligning research focus with emerging global chemical engineering challenges and technologies.
