Q1What I Studied
I majored in sociology in my master’s program, and did art-based research. In that field, research findings can be expressed through art as well as academic papers. I focused on passing on war experiences, so I put together a performance using T-shirts and a video installation using footage I'd found, and I presented these at academic conferences and museums.

Q2Why I Joined SEGA
Gaming is a hobby that I've been passionate about since my student days, and that passion stuck with me even as I worked on videos, novels, and installations. Games are composite works of art that put together visuals, sound, and scripted sequences with player input to create a moving experience, and are able to deliver that experience to a wide audience. I wanted to work in the video game industry to create a game that was both artistic and commercial. Another reason I chose to work at SEGA is because they welcomed a newbie like me with open arms, even after I bragged at the interview that I could make better games than them.
Q3My First Assignments at SEGA
When I first joined the company, they had me doing checks for mobile games. As a game designer, I was checking whether new implementations had any issues and making sure fixes had actually worked. Games in development have lots of issues, and thinking about the causes of those issues was a kind of on-the-job training. I learned how games take shape through the specifications, the implementations, the contributions of different team members. This experience gave me a strong foundation that I use even now as a game designer.

Q4Biggest Surprise After Joining SEGA
A nice surprise for me has been how many chances we have to travel abroad, even people in game development roles. I thought only those in certain positions would have that opportunity, but there are chances to attend playtests and game shows overseas while working on global console titles. Getting to travel make the scope of my work feel global. I've also conducted playtests and been a speaker in the U.S., as well as handled local ops and presentations for the titles I was working on.

Q5Current Duties
I'm currently the lead game designer for Crazy Taxi: World Tour. We started off with a small team that laid the foundations for the game—the controls, game mechanics, things like that. Now that we're nearing the end of development, I manage a team of dozens of game designers, so there's a lot on my plate. Budgeting and head counts; keeping the project on track; fine-tuning things with our overseas offices; marketing and PR; making announcement videos; and getting ready for presentations and events.
