The Japanese are remarkably ingenious when it comes to harvesting tea. In the rest of the world, the leaves are hand-picked by legions of workers, but in Japan, labour is really expensive and so the growers have to do it themselves. This means using machines, each as well designed as the next. The quality of production is not affected by this mechanisation, as the Japanese are generally meticulous and take great care to do everything properly. Once the leaves have been gathered at the processing site, a sophisticated tool with an electronic eye is used to check that their shape, size, structure and colour are of the required quality.
