TOKYO -- Japan's minister in charge of cybersecurity is in the spotlight for acknowledging he has never used a computer and making comments showing he has no idea what a USB port might be.

Ruling party lawmaker Yoshitaka Sakurada, also in charge of the 2020 Tokyo Olympics, was replying Wednesday to questions from independent and opposition legislators.

"I give instructions to my aide and so I don't punch into a computer myself," he said. "But I am confident our work is flawless."

When asked about the power grid and malware, Sakurada said USB was "basically never used" in the utility systems, appearing to not know what it might be.

Lawmakers laughed incredulously at his replies, which were highlighted in Japanese media. Questioning and answers in Parliament are also carried live on national TV.

Ministers in Japan almost always get parliamentary questions in advance. Often their answers are based on briefings from ministry bureaucrats. In Sakurada's exchange, bureaucrats were seen rushing over to give him sheets of paper with information.

Ministers are tapped by Prime Minister Shinzo Abe, and Sakurada was named to his position in the latest Cabinet reshuffle last month.

Although the minister is not expected to have much hands-on responsibility in the handling of either cybersecurity or the Olympics, Sakurada's high-profile bungling is an embarrassment for Abe.

Sakurada, 68, a graduate of Meiji University, was first elected to parliament in 1996, representing Chiba prefecture, near Tokyo.

His favourite issues are pushing for Japan's economic prosperity and supporting its culture. "There is no genius that surpasses effort," is his favourite motto.
