    I have been in this industry for about 20 years now but still excited seeing new technologies coming out to evolve the way companies communicate to their users. At Rakuten AdRoll, we also have huge amount of user data including purchase data which we are able to use on top of our technology so we can develop new and differentiated solution for our customers. Outside of work, I have 2 pugs and love to travel with them to Lake Yamanaka. I also like to play golf and baseball.

    At Rakuten AdRoll, we openly share our own experiences and knowledge from different career, culture, and language background to create new business opportunities and build a unique work culture in Japan market. Upon nearly 20 years of my experience in the industry, I continue to enjoy meeting and working together with talented people to “curate” our global ad technology into something unique for clients in Japan. I enjoy Ikebana (flower arrangement) and playing golf outside of work.

    Partner Manager

    After several years of working as an IT salesperson, I decided to join Rakuten AdRoll with the expectation of adding diversity, development and challenge to my career. I was very nervous at first due to lack of experience in the advertising industry as well as programmatic products. However, I have been able to learn so much through online training programs, hands-on sessions and 1:1 meetings with colleagues around the world. The unanticipated, yet superb company culture is surely my favorite thing about working here. At Rakuten AdRoll, everyone is encouraged to participate and express our ideas to grow the organization from different perspectives. I really appreciate the roll-up-your-sleeves and do-more-with-less mentality because it gives great ownership and inspires me to work more efficiently. I also find myself among a great group of talented people with diverse backgrounds who share their knowledge and face challenges with me. If you also love having fun while working and helping others to succeed, chances are you’ll like rolling with us.
