AM Best, the credit rating agency, is maintaining its stable outlook for Japan’s non-life insurance industry, reflecting improved underwriting fundamentals, especially in the fire insurance segment, and the positive impact of stronger regulatory oversight.
The Financial Services Agency (FSA) has taken a more assertive stance over the past 18 months, focusing on industry conduct and governance standards.
Recent measures have targeted agency networks and incentive structures, with the intent to improve market fairness and internal controls.
Although these changes bring near-term cost pressures, they are expected to enhance operational transparency and strengthen long-term cost efficiency.
Market reforms have also prompted leading non-life insurance groups—Tokio Marine, MS&AD, and Sompo Holdings—to accelerate the sale of their strategic equity holdings.
This shift, driven in part by regulatory encouragement to reduce market exposure, is improving capital efficiency and lowering balance sheet risk. The realised gains from these disposals have supported recent profitability, while the move toward more diversified and less volatile investment portfolios is expected to enhance capital resilience over time.
AM Best views this strategic reallocation of assets as a positive step toward more stable and sustainable financial positions among major insurers.
In the fire insurance line, structural adjustments have helped mitigate the financial strain caused by an uptick in natural catastrophes.
Japan has faced a noticeable rise in severe weather events, including typhoons and heavy rainfall, which have contributed to heightened claims volatility. Insurers, guided by recommendations from the General Insurance Rating Organisation of Japan, have responded by raising premiums and tightening underwriting standards.
Measures such as shortening renewal terms for homeowner policies and adopting more precise pricing models based on location and property characteristics have led to better alignment between premiums and risk exposure. These changes are contributing to improved rate adequacy and setting the stage for more consistent earnings in this historically volatile segment.
The investment environment has also become more favourable for Japanese insurers following a significant shift in monetary policy.
In early 2025, the Bank of Japan raised interest rates for the first time in years, ending a prolonged period of negative rates.
With the benchmark rate now at 0.5%, insurers are benefiting from higher yields on reinvested fixed income assets, particularly government bonds. AM Best anticipates that this environment will continue to support investment income over the coming year, providing a tailwind for overall earnings.
Japan’s non-life insurers are also preparing for the upcoming implementation of the Insurance Capital Standard (ICS) in fiscal year 2025, which will introduce market value-based assessments of assets and liabilities.
While the life insurance sector is likely to experience a more pronounced impact, many non-life companies have already aligned their internal capital frameworks with ICS principles, adopting economic solvency metrics in capital planning.
This shift is expected to enhance transparency and facilitate better comparability with international peers operating under similar standards, ultimately improving insurers’ ability to navigate evolving market conditions.
Despite these positive developments, the automobile insurance segment remains under pressure. Claims frequency has stabilised, but rising repair costs—driven by inflation in parts and labour—continue to weigh on profitability.
While insurers have begun to implement modest premium increases and are improving underwriting practices through segmentation and the use of advanced technology, cost inflation is outpacing pricing adjustments. AM Best expects this line of business to remain challenged in the medium term as insurers work to restore balance between claims trends and premium adequacy.
The stable outlook reflects a combination of improved underwriting conditions in certain business lines, stronger regulatory frameworks, and a more supportive investment climate, tempered by ongoing pressures in the motor segment. AM Best believes that these factors collectively position Japan’s non-life insurers for greater operational resilience and more consistent performance in the years ahead.
“AM Best expects that the regulatory shift will lead to increased transparency and comparability for Japanese non-life insurers with global counterparts under similarly advanced regulatory frameworks, equipping them to navigate economic uncertainties more effectively and enrich global competitiveness over the long term,” commented Chanyoung Lee, Director, Analytics, AM Best.
