What will happen to working life expectancy in Japan if the retirement age is increased and mortality rates improve?

Increasing the mandatory retirement age to 70 years can significantly increase working life expectancy among older adults in Japan.

Working life expectancy at age 65 was 4.6 years for men and 3.5 years for women based on longitudinal data.
Improvements in mortality are projected to yield a working life expectancy of 4.9 years for men and 3.7 years for women by 2050.
Raising the retirement age to 70 years is estimated to increase working life expectancy by about 1.5 years for men and 1.6 years for women by 2050.

This study looks at how long older people in Japan might work if they live longer and if the retirement age is raised to 70.

The study used data from five waves of a longitudinal survey and multistate life table methods to estimate and project working life expectancy.

Older adults aged 65 years and older in Japan.
