Japan's Largest Non-Life InsurerNarrow moat

Tokio Marine Holdings (8766) — moat facet

Tokio Marine is Japan's largest non-life insurer and makes about two points more on each policy than the market, in a market that grows 2.5% a year.

Tokio Marine & Nichido Fire, the group's Japanese non-life company, is the largest single non-life insurer in Japan, with 27% of the market; Sompo Japan has 24%, Mitsui Sumitomo 19% and Aioi Nissay Dowa 14%1. The company's own description is that the top three dominate approximately 90% of the market2. In auto insurance, the largest line, its share is 26.3%3.

The largest single company in a market of four.

Size in insurance is valuable because it lowers expenses per policy and spreads risk, but the real test is underwriting. On that, Tokio Marine has an edge it can measure: its combined ratio, claims and expenses as a share of premiums, averaged 93.2% over ten years, against 95.3% for the Japanese market and 99.9% for North America by the company's own comparison4. A combined ratio below 100% means the insurer makes money before investment income; two points better than the market on a premium base of ¥2,596.3 billion5 is roughly ¥50 billion a year6.

The record is not uniform. The combined ratio was 102.2% in the year to March 2019, a loss on underwriting, and 98.7% the year after7, years of heavy natural catastrophes. It was 95.6% in the year to March 2026, and the plan for the current year is 91.9%8.

The Japanese market is also slow. Its premiums grew from ¥8,692.7 billion to ¥9,578.2 billion over the period the company measures, a compound rate of about 2.5%9. Tokio Marine's own Japanese non-life premiums rose from ¥2,116.1 billion in the year to March 2017 to ¥2,596.3 billion in 202610.

The company's history in the market is long: it launched Japan's first auto insurance in 191411. Its current position rests on its agency network, which sells about 72% of its Japanese premiums through professional agents, business companies and car dealers12.

In the first quarter of the current year its Japanese combined ratio was 88.7%, against 86.6% a year earlier13, still well below the full-year plan despite the large liability losses.

The moat is narrow: scale and underwriting skill in an oligopoly, in a market that barely grows and whose regulators have recently found the oligopoly fixing prices. The measure is the combined ratio against the market's. Holding two points better through the current auto rate cycle would show the underwriting edge intact.

Moat trajectory: Holding steady

The share and underwriting edge are steady; the market is flat and under regulatory scrutiny.
