Ever seen a perfectly square watermelon? In Japan, these geometric gourds aren’t a genetic marvel but a deliberate agricultural innovation. Growers place young, developing watermelons into tempered glass boxes, forcing them to conform to the cubic shape as they grow.

This isn’t just for show. Initially conceived in the 1980s by a graphic designer, the square shape serves a practical purpose: easier stacking and more efficient storage in compact Japanese refrigerators. No more rolling fruit hogging precious shelf space!

However, these aren’t your everyday summer snack. Often harvested before full ripeness to maintain their crisp edges, square watermelons are typically ornamental. They’re prized luxury items, frequently given as expensive gifts, with some fetching prices over $100 a piece.

So, while they might not be the sweetest treat, Japan’s cuboid watermelons are a fascinating blend of practicality, artistry, and cultural gifting, proving that even nature’s shapes can be redesigned for convenience.
