As part of its expansion plan, Little Caesars has focused on Canada, Latin America, the Caribbean, Europe and the Middle East Africa region. The chain is just wading into the Asian Pacific region.
Take-and-bake pizza chain Papa Murphy's has also shied away so far. It currently has more than 1,435 stores in 38 states, Canada and the United Arab Emirates.

Ken Calwell, Papa Murphy's president and CEO, said it plans to grow the U.S. market first, to as many as 4,500 stores.
"We want to make sure we do a great job where we are today and then start to roll out to other countries after that," said Calwell in a phone interview.
Pizza competitor Sbarro hasn't ruled out opening an Italian homecoming.
In an email, Sbarro Chief Marketing Officer Anne Pritz wrote, "As a company whose founding family emigrated from Naples to New York in the '50s, a location in Italy would be a great addition to the Sbarro brand. We currently do not have a presence in Italy, but we are always open to expansion. Our International business is very robust, so it's never out of the question."
But don't expect the U.S.'s biggest pizza player to open there any time soon.
A spokesman for Yum Brand's Pizza Hut wrote in an email that taking Pizza Hut to "Italy does not fit with our global brand story."
Domino's Pizza also isn't active in the market. A spokesman declined to comment further saying "we don't typically comment on markets that we are not present in until we announce them."
