Tanemaru, official mascot of EXPO Y150.

Tanemaru as described at the official Web site: "Tanemaru embodies the spirit of the camphor tree that stands in the courtyard of the Yokohama Archives of History, watching over Japan since the opening of the country 150 years ago. In the year 2009, Tanemaru “sets sail” into the next 150 years, bearing new seeds of vitality for Asia and the rest of the world."
