✦ Japan Life After the Block ReinsuranceThin moat

Tokio Marine Holdings (8766) — the future bets

Tokio Marine's Japanese life business reinsured part of its book and carries ¥1.15 trillion of future profit.

Tokio Marine's Japanese life business, Tokio Marine & Nichido Life, reinsured a block of its business around March 2026, and its life premiums under Japanese GAAP fell from ¥586.8 billion to ¥377.2 billion1. Under IFRS the segment recorded a loss of ¥204.9 billion in the latest year, driven by investment losses of ¥237.6 billion2.

A plan to grow after the reinsurance.

The business's future profit is measured under IFRS by its contractual service margin, the unearned profit on existing policies: ¥1,149.7 billion at March 2026 and ¥1,147.0 billion at June34. The plan for the current year is adjusted net income of ¥82.0 billion, against ¥69.3 billion5, and the first quarter earned ¥21.6 billion6.

On the business-unit measure, the life company earned ¥57.1 billion in the latest year against ¥41.9 billion7.

The life company has also faced regulatory attention: in August 2025 it received a report submission order from the Financial Services Agency concerning its relationships with multi-agency brokers8. Its sensitivity to interest rates is published: a 10 basis point rise in yen rates reduces its net assets by about ¥5.0 billion9.

The measure is the contractual service margin. Growth would show new business adding profit; a decline would show the book running off.

Moat trajectory: Holding steady
