South Africa lock Andries Bekker has agreed a deal to join Japanese side Kobelco Steelers at the end of the 2013 Super Rugby campaign.
Bekker, who has been capped 29 times, has spent his entire professional career at the Stormers, becoming the first player to reach 100 for the franchise.
However the 29-year-old will now team up with fellow Springbok Jacques Fourie at the Steelers.
"It was a tough decision for me to make," said Bekker.
"I've spent my entire professional rugby career in Cape Town but, at this stage of my life, I felt it would be best to further my career abroad and to embark on a new adventure."
