Japan's Rakuten Mobile restores service after system failure

Japan's Rakuten Mobile Inc said on Sunday that its service for users on Rakuten UN-LIMIT VII plans had been restored, after a system failure caused difficulties making calls and sending data for over two hours.

The mobile carrier, a wholly owned subsidiary of Rakuten Group Inc (4755.T), did not say how many users were affected by the issue, which lasted about 2-1/2 hours after starting shortly before 11:00 a.m. local tim, Reuters reports.

It said in a statement that service was restored at around 1:26 p.m. on Septeber 4.

Japan's internal affairs ministry in August issued rare administrative guidance to rival wireless carrier KDDI Corp after tens of millions of users were affected by network troubles in early July.
