The boys kick off their trip in Japan's capital of Tokyo as they try the national sport of sumo and Brad's fear of heights is put to the test on a hanging bridge.

Bradley and Barney’s time in Japan continues as the boys get a taste of drifting and Zen meditation, and Brad is pushed to the edge, literally, when he attempts a bungee jump.

The Walshes reach Osaka as they explore the city in go-karts, learn how to become ninjas, and have a go at the quirky yet growing Japanese sport of pillow fighting.

The boys land in the warmer climes of Thailand for the next leg of their trip as they appreciate the stunning scenery from 1000 feet in the air on a motor-paraglide.

The boys are in Thailand's capital city of Bangkok as they train with a Muay Thai legend and Barney arranges a massage that ends up being anything but relaxing.

The Walshes reach northern Thailand for the final leg of their trip as Barney arranges a great way to see the jungle - a roller coaster that is anything but average.
