Besides sakura flavoured ice-cream and swiss rolls, I also chanced upon sakura flavoured chocolates at Narita airport. Sakura tastes like floral-infused strawberries and can be used in an assortment of food as well as beauty products (e.g. sakura blotters). These chocs are absolutely delish!
I've been suffering from bouts of headaches recently, so I figured little treats like these chocolates and my favourite orangina drink would do me some good. ;)
