Charles Lent points out landmarks from the 31st floor of Tokyo Sankei Building in Otemachi with confidence and pride. After 13 years in Japan he knows more than a few.

For the last seven he has worked in human resources at SAP Japan, a major provider of business software. It's what he calls his "day job."

When first approached for this interview, he's unsure: "I'm just the average 'gaijin' in Japan." Assured there's no such thing as an average foreigner in Japan, that everyone has a story worth telling, he agrees to meet for dinner.
