Toyota's sponsorship with Ireland's most successful rugby province will be worth 5.75 million euro over the next three seasons and includes the title sponsorship of the Munster senior rugby squads competing in the Magners League, Heineken Cup and the British & Irish Cup.
This will bring Toyota's investment in Munster Rugby well beyond the 13 million euro mark, having come on board as the principle sponsor of Munster Rugby in July 2004.
In addition to a basic sponsorship fee, Toyota's commitment to Munster is further highlighted in a continuation of its incentive-based package related to progression through to the final stages of the Heineken Cup and Magners League.
It also provides for continued investment in general marketing, communications and advertising that will help boost the Munster Rugby and Toyota brand images.
"Since 2004 we have been on a magical journey together. One that has seen Munster teams deliver, to their wonderfully devoted fans, two Heineken Cups, a Celtic Cup and a Magners League.
"In tandem with this has been Munster's magnificent achievement in developing a truly iconic and worthy home for the team here at Thomond Park."
Commenting on the sponsorship renewal, Munster Rugby Chief Executive Garrett Fitzgerald said: "Munster have been in partnership with Toyota as our title sponsor since July 2004.
"Toyota's professionalism, understanding and support during this period has played a significant part in the development of our brand and our success on the field.
"The renewal of this sponsorship further confirms Toyota's commitment to Munster Rugby and we are privileged and delighted to have the opportunity to work with Toyota for a further three years, until 2013."
