We encountered fruit bats in 1988 for the first time. Instantly, we were fascinated by these cute animals. Since then we have enthusiastically promoted fruit bats to the public. We are aspiring bat ambassadors or commentators.

We quit our previous jobs in March, 2006. Since then Yushi has been a freelance photographer and a nature writer. Keiko has been a freelance nature writer.

We drove across Australia from June 2006 to June 2007 with a travel trailer, watched Australian wildlife and took pictures of them. After returning to Japan, we have continued to travel to see fruit bats around the world.
