Maybe it really reads アイスクリーム. :)
That's Japanese for ice cream. Because there's something really fun about how the Japanese interpret ice cream (and pizza, but that's a different story). To the point that someone can have a whole blog just on Japanese ice cream.
From where I got this fantastic illustrated guide to making ice cream stuffed mochi. Recipes for this are easily procured elsewhere, but there's nothing like pictures to seeing it in action.
