OSAKA -- Osaka city officials on Tuesday declared the drinking fountains at the Universal Studios Japan theme park safe.

The announcement came a day after park officials admitted that business had dropped by 24 percent in late July and August from last year because of a series of management blunders and coverups.

In early July, it was revealed that a water fountain at USJ had dispensed unfiltered water, which led the city to shut down all 32 drinking fountains in the park at the end of July. In August, the fountains were checked and the contaminated one was repaired.
