Following the mad cow disease scare in Britain and a desire to eat better quality food, Japanese beef is increasing in popularity here, and some farmers are using Japanese techniques to improve the quality of their meat.

Since 2000, farmer David Wynne Finch has been breeding Japanese "wagyu" cattle at his farm in Wales and has seen his beef being snapped up by London's top shops and hotels.

He imported the embryos of mixed black wagyu (literally Japanese cattle) from the United States and implanted them in some standard cross-bred beef cows.
