Japan as a whole may be attracting record numbers of foreign tourists, but a report by McKinsey & Co. indicates that the four major historical regions of Nara, Kamakura, Nikko and Ise Shrine are almost unknown among Western tourists.

The consultancy's Japan office surveyed over 3,000 visitors from Western countries on how aware they were of 36 tourist attractions, most of which are listed in major travel guides that cater to both wealthy older Western tourists and their younger counterparts who travel more cheaply.

Only 9 percent of those surveyed said they were aware of Kamakura's attractions in Kanagawa Prefecture, such as the Great Buddha, while 7 percent said they knew of Nara Prefecture's attractions like Todaiji Temple.
