Things I love about spring in Japan: seasonal treats

Spring has to be one of the best seasons (in my opinion, anyway) for tasty treats. There are so many places at the moment that have their own takes on sakura flavored goodies, from drinks at places like Starbucks and Tully's, to donuts at Mister Donut. 

It's decidedly not spring-like yet where I live, so I appreciate all the fun items popping up at various stores to remind me that eventually all the snow out here will melt.

Have you seen any sakura-themed goodies popping up at stores near you? Do you have a favorite season for seasonal flavors?
