While leasing and selling cars is a long way from wanting to emulate Miles Davis, Colin Shea has no regrets.

As the sales manager of Lease Japan KK, an expat car sales and leasing company which opened an office in Tokyo's Azabudai earlier this month, he is 100 percent happy and at home.

"Cars and the car trade have taken me all around the world." Now Lease Japan is offering a new product — a personal portable navigation system — that is going to make life easier for not only expats in Japan, but also Japanese. It's not only foreigners who have a hard time finding their way around."
