Collagen. The word may feature at the less appetizing end of the British lexicon, but for any self-respecting Tokyoite, eating collagen at a beauty restaurant is all the rage. Among the chicest beauty establishments is One Garden.

It may be a stylish minimalist space with wooden floors and subtle lighting but the décor is eclipsed by the food: a complete beauty menu has been created by the chef, enabling guests to eat themselves beautiful. While most people would opt to rub collagen onto their skin in the form of expensive creams, in Japan, a vast swathe of the demographic believe that eating it in food creates peach-soft ‘puru puru’ skin. And collagen steals the show across the menu at One Garden.

Highlights include a Japanese-style bouillabaisse – a fish stew supplemented with melted fish collagen balls. There is also tomato salad with a collagen dressing, collagen-enhanced tofu and green tea pudding boosted with – you guessed it – collagen. And if this doesn’t make your skin ‘puru puru’, nothing will.
