About our food

Hakata-style ramen, our way.

Inspired by the bowls we grew up on in Fukuoka, Japan. Rich pork Tonkotsu, a creamy chicken broth, and a silky plant-based broth of our own. Handmade gyoza dumpling in original, vegan, spicy, and curry flavors.

Cooked with care and served with pride. Come in for a bowl!

Our story

From Fukuoka to SoCal

We learned ramen in the shops and street stalls of Fukuoka, where Hakata-style bowls are part of everyday life. KOTSU® brings that here: quick service, careful cooking, and a broth we're proud to put our name on.

We're hiring.

At KOTSU®, we live by kazoku, which means family. It starts with our crew, in the kitchen and at the counter, and extends to every guest we serve. We take real pride in every bowl. If that sounds like your kind of place, we'd love to meet you.
