There were certain things in Japan that I wouldn't touch with a 10-foot pole when I first got there. This is one of those types of things. Now, if I had a 5,133-foot pole, I'd use it to get my hands on one of these babies. For a mere 150 yen and weighing in at only 191 calories, you can enjoy this "Uchi Cafe" treat at limited Lawson convenience stores. It was available from May 7, 2013, so it should be around for a wee bit, but don't count on seeing it for terribly long. These things tend to have a short lifespan as they are marketed at the fickle affections of young women who value novelty.
The outside is soft mochi and is filled with sweet bean paste that has a whipped cream center. The package comes with "black honey" sauce, or "kuromitsu" and it's sprinkled with kinako (toasted soybean flour). I'm sure that it doesn't come with an elegant little dish or wooden stick, but I'm sure you can transfer it from it's plastic package to a more fitting serving situation. This is part of the "premium sweets" line, which focuses on incorporating cream into the treats.
This is one of those treats that would hit every mark with me - mochi, whipped cream, kinako, and anko, though I would probably skip the kuromitsu.
