Who would have known? Sweet, sweet, Tokyo

So I went to Japan and all I was thinking about was fish. Fresh, raw, dried, oh and heaps of rice and all sorts of odd things that I wouldn't be able to identify but would try anyway. 
I was not expecting (and neither were my hips) the amount of pastries and cakes, the abundance of cafes, and food halls selling everything from frozen marshmallow treats to green tea cakes filled with sweet bean paste. 
After a long day out I ran into the shops for a few cakes to take back to the hotel for the most decadent sugar hit.
