Some Kind of Yellow Oranges from Japan

I picked this up in the Japanese fruit section of the supermarket. They looked like lemons from a distance, but upon closer inspection, they were shaped like oranges...and were also labeled as such. I bought a pack just to see what yellow oranges would taste like.

Well, there's probably not much to say aside from the fact that they tasted like sweet oranges (very mild ones, anyway). And to my surprise, they were the thick-skinned peelable kind...with seeds. Interestingly, they also had some little mikan-like yellow ones on sale too. But there wasn't really anything so exciting about these that I'd run right back for them.
