TOKYO (Reuters) - Japanese trading house Mitsubishi Corp 8058.T plans to set up a joint venture with U.S. data center operator Digital Realty Trust DLR.N and build around 10 data centers in Japan by 2022 for 200 billion yen ($1.8 billion), the Nikkei said on Saturday.

Tokyo-based Mitsubishi expects the centers to help meet growing demand for information storage from customers of California-based Digital Realty and generate sales of around 20 billion yen to 30 billion yen in 2022, the business daily reported, without citing sources.

The two companies could invest an additional 300 billion yen in the medium term, the Nikkei reported.

Mitsubishi could not be reached for comment.
