U.S. lobster fans won't have the same luck, as there are no plans to offer the sandwiches outside of Japan.
"No plans for a lobster-and-hamburger sandwich here," Wendy's spokesman Bob Bertini told The Columbus Dispatch.
The new sandwiches are part of Wendy's effort to get a foothold in the Japanese market. Wendy's relaunched its franchise-expansion efforts into Japan in December 2011. But the seafood sandwiches will not be as affordable as the regular menu items and will reportedly cost around $20.
"Each market is different and seafood is a big part of the diet in Japan," Bertini told CBS Cleveland.
Some other unusually posh items on the Wendy's Japan menu include a porcini grilled chicken sandwich and a foie gras Rossini.
