Ginza Sembikiya, Setoka no Mousse

I had an excellent first cake, so I finally followed up and got this cake. On the minus side, once you take the plastic away, it's not that good at supporting itself, but so it goes. The official photo is a little better, but they went for texture over strength, which I appreciate. This from Ginza Sembikiya, maybe the least widespread of the Sembikiya. They have a main shop in Ginza, but also a counter at Ginza 6, where I went, since I was coming from Mitsukoshi and it's connected underground, though I guess the main shop almost is. They also had a +1000 yen sponge strawberry cake (which is huge for a piece of cake in Japan), but I passed. This is Setoka no Mousse, where Setoka is a kind of mikan, as one can see. It's really nice and I can say excellent, especially since I don't get so many mikan cakes. The mousse is mascarpone cheese, of course, so it's just a medium. I guess I'm going to need to get back there and try the strawberry cake. Hopefully I can get it when I can split it with someone.
