The Japanese are pretty strange about a lot of things, none more so than melons, which are commonly given as gifts. The usual gift melon is a cantelope, though honeydew and watermelons are also given. Japanese farmers have developed a square watermelon, which they have designed so it exactly fits Japanese refrigerators. (Which is another bit of Japanese weirdness: there are two sizes of refrigerators. Period. One that’s maybe three-quarters of a cubic foot, and one that’s a couple of cubic feet. Ten- or twenty- cubic foot refrigerators like Americans and Europeans use do not exist.)
