Weird but Useful Japanese Products That Don’t Exist Anywhere Else

These Watermelon Cubes Are Real

These famously unique fruits at Japanese markets look like they belong in a video game. If you’re someone who loves symmetry, you’ll want to check out Japan’s cube-shaped watermelons, known as "shikaku suika." Farmers grow these melons inside tempered glass molds to achieve their perfect geometric shape. But here’s the catch—these watermelons aren’t edible. To keep the cube shape intact, they must be harvested before ripening, leaving them too unripe to eat

So why bother? Japan decided the traditional round watermelon could use a creative twist, and these square versions have become a quirky novelty. They’re often sold as decorative items or gifts rather than food. Have you ever seen a fruit so perfectly shaped? While they might not satisfy your sweet tooth, they’re a fascinating example of how innovation can turn even the simplest things into art. Next time you’re in Japan, don’t miss the chance to see these eye-catching melons for yourself!
