About
Koku Ramen occupies a singular position in Brussels' ramen scene: it specialises exclusively in iekei-style ramen, the Yokohama-born style characterised by a rich tonkotsu-shoyu (pork bone and soy) broth, medium-thick straight noodles, and classic toppings of chashu, spinach and nori. A Japanese company opened it in March 2019, as confirmed by an Instagram post at launch. The noodles are handmade and pulled fresh daily; all broths are made entirely on-site. The result is a bowl that has prompted Japanese expats and visitors — the most demanding judges — to rate it among the best ramen they have eaten even by Japan's standards: 'Even if you are in Japan, you will want to go there many times.' The restaurant posts operational schedule updates on Instagram (@koku.ramen) as it adjusts hours to manage demand and quality.
