Our Story


Inspired by the nature-spirited roots and duality of Mount Fuji, KOYN, our contemporary izakaya, brings a unique balance of modernity with tradition through a two-folded dining experience.

The kitchen led by Executive Chef Rhys Cattermoul presents a menu inspired by this natural duality and showcases a broad spectrum of Japanese cuisine through delicate umami flavours and responsibly sourced ingredients.

KOYN’s philosophy places value on subtlety and detail through an amalgamative lens where Japanese art, design, and textile traditions meet culinary craftsmanship.
