Japan insurers’ gains erode amidst rising costs

Firms are shifting product mix toward dementia and care coverage for older clients.

Japan’s life insurers will likely maintain a stable outlook despite economic uncertainty, supported by macroeconomic conditions and improving investment returns.

Charles Chiang, senior financial analyst at AM Best, said Japan’s economy is expected to grow modestly, with the International Monetary Fund forecasting real GDP growth of about 1.1% this year, slowing to 0.6% in 2026. 

The higher interest rate environment is supporting life insurers by improving investment yields and spreads, helping offset the impact of slow economic growth.

Japan’s life insurance market remains mature and highly penetrated, with premium income broadly stable. 

However, demographic pressures from an ageing and shrinking population continue to weigh on growth.

Insurers are adjusting their product mix in response. 

Demand for savings products, particularly yen-denominated policies, has risen as interest rates increase. 

At the same time, companies are developing protection products aimed at older customers, including cover for dementia, nursing care and health-related services.

Firms are also investing in digital tools and artificial intelligence to support sales as the workforce shrinks.

Investment income is becoming a more important driver of profitability. 

Rising yields on domestic fixed income assets and the gradual runoff of older policies with high guaranteed rates have improved investment spreads. 

Insurers are also rotating their portfolios, selling lower-yielding Japanese government bonds and reinvesting in new issuances offering higher returns, with 30-year bonds yielding around 2.5% to 3%.

In addition, companies are reducing exposure to domestic equities and increasing allocations to alternative assets and higher-yielding fixed income investments to improve risk-adjusted returns.

However, higher operating costs are partly offsetting these gains, as inflation pushes up wages and firms increase spending on technology and regulatory compliance.

Beyond the domestic market, Japanese life insurers are expanding overseas and into non-insurance businesses such as healthcare services and corporate benefits. 

Over the past year, several transactions have taken place in regions including North America, Australia and South Asia, as firms seek to diversify earnings.

On the regulatory front, Japan’s Financial Services Agency is introducing a new economic value-based solvency framework, the Japan Insurance Capital Standard, from the fiscal year ending March 2026.

Industry readiness is high, with most major insurers already reporting internal solvency ratios well above 200%, compared with the 100% minimum requirement.

AM Best said these factors, including stable premium income, stronger investment returns, ongoing diversification and a smooth regulatory transition, support its stable outlook for Japan’s life insurance sector over the next 12 months.
