As Japan's best English social media aggregator, Katz funded JapanExp and YokosoNews to provide travel, culture and lifestyle information of Japan.

Katz was born and raised in Yokkaichi, Mie, Japan, then moved to Los Angeles to pursue his dream to become a filmmaker. After graduating from California State University, Long Beach, he has worked on dozens of independent film projects as well as national TV programs as a producer; in post-production, and sound designer.

In 2009, he joined an open source software project, concrete5, to start translating and marketing in Japanese.

In 2010, after years of preparation, he launched a social media web project, JapanExp, to explore, express and export Japan. As one of its projects, he launched YokosoNews to introduce travel, lifestyle and cultural information of Japan to, and welcome people to visit from overseas.
