"So which of the two countries do the islands really belong to?" entrepreneur Song Wenzhou was asked recently by his 10-year-old son amid the rising tensions between Japan and China over the Senkaku Islands.
In mid-September, his family watched as throngs of Chinese demonstrators marched past their home in Beijing toward the Japanese Embassy next door.
The China-born Song, 49, has spent many years doing business in Japan and is deeply troubled by the strained ties. His wife is Japanese and their two children also hold Japanese nationality.
