Tokio Marine Holdings (8766) — moat facet

Tokio Marine's customers range from Japanese drivers to American niche businesses, and none is large enough to name.

Tokio Marine discloses no customer accounting for a material share of its revenue. Its customers are millions of Japanese car owners and households, Japanese companies, and specialist customers of its American businesses.

Japan P&C premiums by line, year to March 2026 (¥ bn)1,232.1Auto1,364.2Other linesTotal ¥2,596.3bn; Tokio Marine results presentation, May 2026
Auto is almost half.

In Japan, the largest line is auto insurance, with premiums of ¥1,232.1 billion in the latest year1. The company sells through agents, business companies and car dealers2.

Its corporate customers are changing their relationship with it. Many of them had shareholdings exchanged with Tokio Marine, and the company is selling all of its strategic equities by 20303. By September 2024, 90.3% of policy owners had agreed to dissolve excessive-cooperation arrangements4.

Abroad, the customers are specialist: small commercial businesses for Philadelphia, employers for Delphi, wealthy households for Pure56.

The first quarter of the current year showed the customers paying more without leaving. Auto claim frequency was unchanged and unit prices up 7.5%7; international premiums grew 16.6% in yen8.

The measure is premium retention through the changes. Stable Japanese corporate premiums after the shareholdings are sold would show the customers staying for the product.

Moat trajectory: Holding steady

No concentration; corporate relationships changing.
