Rex and his team explore Japan, Land of the Rising Sun and computerised reel! 

We see not only incredible diverse fish on offer but also gain an insight into the various fishing methods that the japanese have made their own. See the local fishing markets in Osaka as they auction off their internationally-renowned fresh tuna. Visit the magically tranquil Osaka Castle and see the only whale shark in captivity at the Osaka aquarium. Immerse yourself in the Nagara river, where the locals gather to catch ayu, and experience night-time cormorant fishing where handlers get their birds to regurgitate their fish to land their catch.

We also explore one of the South Pacific's best kept secrets, the Republic of Vanuatu with its 83 individual islands, friendly people, active volcanoes and crystal clear water. It is in this paradise that Rex lands giant and blue trevally as well as luna trout. He also releases a 12-month turtle back into the ocean and we see Rex's sidekick, Steve Starling, swim with a playful sea cow.
