Some 17 million Japanese a year fly overseas, according to government statistics. Among them are what the tourism and aviation industries might call "connoisseur tourists."

These travelers have developed interests in less-common spots, including St. Petersburg's Hermitage Museum or the Alaskan glaciers, and the industry must cater to those needs, travel agency officials said.
