Our restaurant, located on Mayfair’s prominent Grosvenor Street, is inspired by the nature-spirited roots and duality of Mount Fuji, honouring Japanese traditions and culinary craftsmanship.
Executive Chef Rhys Cattermoul showcases a broad spectrum of Japanese cuisine through delicate umami flavours and responsibly sourced ingredients.
