Square Watermelons

Shikaku suika (square watermelons)
It’s interesting how doing things differently can grow into popularity. A farm in Shikoku, Japan started growing watermelons in specially-made glass boxes, which forced the melons into a cubic shape. This innovation became a symbol of Japan's novelty. However, the market for these melons is very small partly because they are prohibitively expensive, costing at least 10,000 yen (around $100).
Besides their curiosity value, square watermelons have some genuine practical benefits. They are easier to stack and package than the round fruit and they are less likely to be damage in transit.
