Plans to create Japan’s largest non-life insurer out today

Japan’s Nikkei newspaper has said Mitsui Sumitomo, Aioi, and Nissay Dowa will detail their merger plan today to create Japan’s largest non-life insurer, Bloomberg reports.

Investors will receive about 0.19 of a share in the merged holding company for each they hold in Aioi or Nissay Dowa with Mitsui Sumitomo investors exchanging stock on a one-for-one basis.

Mitsui Sumitomo is Japan’s second-biggest non-life insurer, AIoi is fourth-ranked Aioi and Nissay Dowa six-ranked. Together they create a company with combined revenue from premiums of 2.59 trillion yen ($29bn) in the year ended March. That overtakes Tokio Marine Holdings’s 2.13 trillion yen in sales.

The 2025 Insurance Times Awards took place on the evening of Wednesday 3rd December in the iconic Great Room of London’s Grosvenor House.

Hosted by comedian and actor Tom Allen, 34 Gold, 23 Silver and 22 Bronze awards were handed out across an amazing 34 categories recognising brilliance and innovation right across the breadth of UK general insurance.
