POSH, a raw food patisserie in Tokyo, launched 2 types of vegan and gluten free birthday cake.
One is Mature Mango, which is made of mango fruit from Miyazaki prefecture. JPY 17,000.
The other is Honey Glow Pineapple; the pineapples are selected by Daiwa Supermarket, which is famous for its fruit sandwich (which is not vegan, unfortunately).
The shop is in Koto, Tokyo and its website is below.
