Universal Studios Japan has attracted a record number of visitors in fiscal 2015, topping the previous 12.7 million mark set the year before, the Osaka theme park operator said Monday.

Given the continued popularity of an attraction area based on the "Harry Potter" film series that opened last year and limited-time events like Halloween, USJ Co. believes the figure could eventually top 13 million by the March 31 end of the fiscal year.

"We want to achieve 14 million or more visitors by continuing active investments into constructing new attractions," Tokuhei Murata, the company's executive officer, said at a ceremony celebrating the new record.

The theme park is scheduled to start operating a roller coaster based on the "Jurassic Park" film series on March 18, while increasing promotions for anime- and game-inspired events, it said.

The theme park, located in a waterfront area of Osaka, has been a major tourist draw since opening in 2001.
