# 太陽生命保険


## Wiki route

This entry sits under [[life-insurers/INDEX|life-insurers INDEX]]. Read it against [[life-insurers/daido-life|大同生命保険]] for peer / contrast context and [[insurance/INDEX|insurance index]] for the broader system / regulatory boundary.

## TL;DR

太陽生命保険株式会社は、[[life-insurers/td-hd]] group の major life-insurance operating company。[[life-insurers/daido-life]] が SME / owner market に強いのに対し、太陽生命は household / individual protection market の operating arm として見ると T&D group の split strategy が読みやすい。

## 2. Operating model

太陽生命は、individual life-insurance products, health / medical protection, household-oriented sales channels を中心に見る insurer。T&D group の中で [[life-insurers/daido-life]] と並べることで、同じ holding company 内でも customer segment, channel economics, product risk profile が違うことを表現できる。

FinWiki では [[life-insurers/td-hd]] group strategy, life-insurance channel mix, economic-value solvency regulation の議論から参照する operating-company anchor とする。
