Japan Post Insurance outlook steady as profitability shows gradual lift

Moody's said Japan Post Insurance is stable thanks to conservatism.

Moody’s Ratings expects Japan Post Insurance Co., Ltd. to maintain a stable financial position supported by its strong market share, solid capitalisation, and prudent asset management, despite ongoing pressure from weak profitability and limited distribution channels.

The insurer’s liquidity and capital levels are expected to remain strong, with a 12.5% adjusted capital-to-assets ratio and an economic solvency ratio of 204% as of March 2025. 

Moody’s said Japan Post Insurance’s conservative investment and acquisition approach supports its stability.

Profitability remains a weak spot, with a five-year average return on capital of 1.8%. 

However, earnings have improved due to better investment performance, higher interest margins, and lower hedging costs. 

The agency expects rising domestic interest rates to further lift returns on Japanese government bonds.

Japan Post Insurance’s dependence on post offices and captive retail channels continues to limit its sales diversity. 

Still, its strong government links provide additional support, with Japan Post Holdings owning 49.8% of the insurer and the government holding 38.8% of JPH.

Moody’s said the insurer’s outlook is stable and could improve if profitability strengthens and distribution channels expand whilst maintaining financial discipline.
