Minimalist lifestyle brand Muji’s U.S. subsidiary has filed for Chapter 11 bankruptcy protection, its Japanese owner Ryohin Keikaku Co said on Friday, joining the list of casualties from the coronavirus pandemic.

Ryohin Keikaku said Muji aims to close unprofitable stores and renegotiate rents in the United States, where its 18 stores have been closed since mid-March due to the pandemic.

The outbreak has inflicted widespread financial pain on global retailers, leading many such as J. Crew Group and Brooks Brothers to file for bankruptcy protection.

Ryohin Keikaku said the U.S. filing will not affect its operations in other markets.

But the business has also been hit by store closures and weak consumer spending in its main market, Japan.

Separately on Friday, Ryohin Keikaku reported an operating loss of 2.9 billion yen ($27.2 million) for the quarter through May.
