Well this was a first. Found in Okayama. Strawberry flavoured Dorayaki gong cakes filled with strawberry milk filling.
Usually the outside pancake-ish layer is plain with a traditional filling of sweet red beans. These days they sometimes contain matcha (green tea) in the pancakes and also folded through whipped cream which can accompany the red beans. Also it is becoming popular to fill the gongs with various flavours of custard. But I've never seen one quite like this. Shoulda grabbed one.
