Japan Our World Cup coverage continues with an unexpected cross-cultural treat from Japan. Okinawa, Japan may not be first place you think of when you think of ice cream, but it turns out the island is crazy about it! Ice cream came to Okinawa with American troops in WWII, but became a trend that lasted much longer. The main purveyor is Blue Seal, originally founded to provide troops with a taste of ice cream from home, but eventually the ice cream became available island-wide, where it has gained quite a following. There are flavors that Americans would be familiar with, as well as Okinawan flavors like sugarcane, bitter melon and purple sweet potato. Blue Seal-branded cafes are found all over Okinawa, and now even in Tokyo, too. Softserve is more popular in Japan, but Blue Seal definitely holds the top spot for American-style ice cream.
