I joined Google at 2007 and was playing a wide-ranging role in key products supporting the revenue of online businesses, including online advertising, search, and policies for AdSense and AdMob. Particularly in the search domain, I've been active as an evangelist for over a decade, answering Google search-related queries on YouTube and giving speeches in regional areas. Furthermore, through collaborations with blog hosting companies and managing industry associations in the Trust & Safety field, I've dedicated my efforts to combating internet fraud in Japan and raising the industry-wide standards for new countermeasures. I've also been personally involved in information literacy education, conducting search lectures at local governments and universities. In May 2023, I left Google LLC and founded Digital Evangelist Inc.
