Before coming to Japan, I was not a fan of fresh oranges, though I did like orange-flavored foods. Most of them didn't seem to have much taste, and I didn't like the texture. Since coming to Japan, I've found that there are some much more flavorful options on the orange front. One of those options is dekopon (marketed as "sumo citrus" in the U.S.), a variety of orange with a protruding navel that is aged to develop the sugars. It's more intensely flavorful and sweeter than common Western varieties such as navel oranges.
I'll miss easy access to dekopon.
