Yatsuhashi is a Japanese desert sweet. It is particularly well known as a product of Kyoto and can be bought at many of the tourist stores around the Temples.
Yatsuhashi is made from rice flour and sugar and has a soft, mochi-like texture. You can find many different flavors of Yatsuhashi, which are created by adding a filling inside the mochi.
The guy above was handing out samples of the orange, mikan, flavored yatsuhashi. Really tasty.
There are always some great signs in Japan. You can figure out easily enough what they mean, usually, but it always give you a bit if a laugh when you first see them. This one at the Yatsuhashi and Ice-cream counter was really nice. No leftovers in the street please!
