How to read the Scientific research, professional services sector data
Overview
The weighted-average annual income for Scientific research, professional services sector is ¥6,494,000 (sample: 1,193,810 workers). That is +27.9% above the national average. The figure is computed across age bands from the official wage census, capturing real working conditions across gender, industry, and company size.
Age-band peak
Scientific research, professional services sector earnings peak in the 55-59 age band at ¥8,321,000. The steepest jump occurs in the 25-29 band — typically a milestone where compensation accelerates. A peak that arrives early signals performance-driven pay; a later peak suggests stronger seniority weighting.
Gender gap (30s)
In the 30-34 age band for Scientific research, professional services sector, the female-to-male income ratio is 81.2% — a gap of 18.8 pp. Japan's overall norm in this band is 75–80%; values below indicate a wider gap, values above indicate parity. Occupational mix (field vs. office), employment-type imbalance, and post-maternity career paths all contribute.
Earnings curve
Scientific research, professional services sector age-band curve is classified as inverted-U (mid-career peak). The inverted-U is the Japanese baseline (peak just before retirement, then re-employment dip). A rising curve means specialization compounds with experience; a flat curve means experience has limited compensation impact.
