1. When you came to Japan in 1998, what was the biggest culture shock you faced? The language. Even figuring out restaurant menus was a challenge, it was great that they had the plastic food displays.

2. What was the biggest surprise? The first day of my orientation at Sophia University, I got lost. I asked someone the way, and the person walked me to my destination. Experiencing such kindness was so impressive.
