Kazuki Kamada lives the life he loves — just like the over 4,000 fellow YouTube creators he works with.

"I love reading manga. I love playing video games. And I love watching online videos," the 34-year-old chief executive officer and representative director of Uuum Co. told The Japan Times.

"I believe having a background in all of these areas makes me the best-suited person to be president of this company," he said at Uuum's office in Roppongi Hills, the office and residential complex now home to top-tier companies and rapidly growing ventures.
