Tokio Millennium Re Ltd. (abbreviated as TMR) is a reinsurance company headquartered in Hamilton, Bermuda[1] with branches in Stamford, Connecticut, USA,[3] Zurich, Switzerland[4] and Sydney, Australia.

TMR was expected to start its operation beginning of April 2000 with Shin-ichiro Okada named as CEO.

[18] In September 2004, Standard & Poor's affirmed TMR's AA− rating and upgraded the outlook from negative to stable.

The rating was assumed to reflect TMR's excellent financial strength, favorable operating performance over the last several years and its prudent risk management practices.

The decision of A. M. Best was based on TMR's expansion into standard lines of reinsurance, conservative investment portfolio, and strong capitalization, thanks to it being a wholly owned subsidiary of Tokio Marine & Nichido Fire Insurance Co., Ltd.[11] In 2011 TMR was elected one of the "Top 10 Employers That Stand Out in Bermuda" by the Bottom Line magazine.

[26] During the award ceremony, the Bermudian Minister of Economy, Trade & Industry Kim Wilson addressed the winners: "You have persevered despite the tough economic climate to not only ensure your businesses have thrived, but you have worked very hard to make your employees feel valued, by offering superior benefits and training, by encouraging a positive workplace environment, by contributing to the community and by employing people who are committed to their roles and to fulfilling your mission and mandate".

[30] In October 2011 a team of TMR employees participated and won first place in the Give Back Games, leading to a donation of US$11,000 for the Bermudian charity WindReach.

[32] In June and July 2012 TMR will support Bermuda Glee, a ten-day intensive in the performing arts for Bermudian students aged 14 to 19.

The 2012 program aims to get 75 young people from different schools around the Island to develop their talents in the performing arts.

Tyler Butterfield won the men's title in sprint distance triathlon, Kristyn Robinson the women's.
