The Japanese are known to be a fruit-obsessed nation. It is where you can find heart-shaped watermelons and white strawberries, and also where a single melon can fetch thousands of dollars. The growers behind these melons tend to their crops with attention, detail and care - and this even means massaging their melons to make them sweeter.
They call this ‘ball wiping’ and it's a widespread practice when growing the prized Yubari melons which command the greatest price. These muskmelons are sold at around $100-$10,000 each (there was one in 2013 that sold at over $15,000) - the video below sums up the craze.
