U.S. Ambassador Howard Baker and other foreign diplomats in Japan are set to present photographs showing unique features of the country at an exhibition that begins Thursday in Tokyo and then moves to Osaka.

The exhibition, believed to be the biggest of its kind in the world, will showcase about 80 pictures by 51 diplomats from 23 countries.

Organizers and participants said this year they will dedicate the event to the memory of Prince Takamado, who died last November of heart failure while playing squash in Tokyo.
