Get ready to explore! 1. Square watermelons  They were invented back in the 70s by a graphic designer to fit compactly in the fridge and be cut more easily. Japanese farmers grow them in special containers to get the shape. Since they are pretty expensive, people don't buy them as food, but rather as a decorative item. 2. Bizzare flavors of kit-kat  Chili pepper, wasabi, sweet potato, grilled corn, soybean, salt watermelon, mango, green tea - yes that's only a shortlist of the KitKat flavors you can try in Japan.
