The chief executive of sports streaming service DAZN insists the problems that plagued the much-trumpeted launch of its J. League coverage have been fixed, and remains confident that it can revolutionize the way that Japanese fans watch sports.

"We are disrupting, we are breaking new ground," James Rushton told The Japan Times in an exclusive interview before last weekend's J. League fixtures. "And we will not rest until everything is 100 perfect, 100 percent of the time."

The British-based Perform Group last year bought the domestic broadcasting rights for the J. League in a 10-year, ¥210 billion deal, making all matches in Japan's top three soccer divisions available to customers via DAZN on all computers and mobile devices.
