In 2001, for practical reasons, Japanese farmers from Zentsuji found a way to grow square watermelons by inserting the them into square, tempered glass cases while still growing on the vine.

“The square boxes are the exact dimensions of Japanese refrigerators, allowing full-grown watermelons to fit conveniently and precisely onto refrigerator shelves.”

Each square watermelon sells for 10,000 yen, which is equivalent of about 82 USD. Thus, we learn that saving space in your refrigerator is apparently more important than saving money. Grow your own, learn how at Instructables.

If you thought it couldn’t get any better (or more expensive), in 2009, Hiroichi Kimura, a farmer from Kumamoto, and his wife created heart-shaped watermelons to symbolize their love for each other and for their profession– they sell for 15,750 yen, which is about 160 USD. Now that’s what you call maximizing. Sweet.
