Most Hong Kongers are enthusiastic about Japan — its fashion and pop culture have been popular for years, hundreds of thousands vacation in the country each year, and more of its food is imported there than anywhere else, with fresh sashimi flown in daily from Narita airport.

But after the March 11 disasters and ensuing nuclear crisis, people in Hong Kong understandably started to question whether Japan was safe and began urging relatives and friends visiting the country to return home.

On Sunday, the book "Japan, Restarting," written by 22 Hong Kongers living in Japan, went on sale in Hong Kong, recounting their fears, difficulties and perspectives on Japan in the aftermath of the catastrophe, as well as the reactions of their relatives back home.
