The retailer of Muji products is considering moving its European headquarters out of the U.K. because of Brexit, in what would be at least the second such shift by a Japanese company.

Ryohin Keikaku Co., which sells everything from furniture to kitchenware under the Muji brand, is weighing Germany as the most likely site for a new European base, according to a person with knowledge of the situation who didn't want to be identified because the plans aren't public. It isn't clear how many of the roughly 50 employees based at its London offices would move if the company goes ahead with the relocation, the person said.

"As a company we're reviewing the risks from Brexit and always considering all available options," a spokeswoman for Muji, which has 12 U.K. stores, said by email. "We have not made a decision on moving our office since no new location has been decided on."
