Tonkotsu ramen Hakata-Fukuoka pork-bone ramen

Tonkotsu ramen is a Japanese noodle soup originating in the Hakata district of Fukuoka City on Kyushu Island, defined by its opaque, milky-white pork-bone broth. Unlike other ramen styles that use clear broths, tonkotsu broth is made by boiling pork femurs, spines, and other bones at a rolling boil for 12–24 hours, causing collagen and marrow to emulsify into a rich, viscous liquid with a distinctive pork-forward flavor and creamy mouthfeel.

The broth is seasoned with a tare base, typically shio (salt) or shoyu (soy sauce), and served with thin, straight, low-hydration Hakata-style noodles. These noodles are firmer and more alkaline than the wavy, thicker noodles of Sapporo ramen, designed to hold up to the dense broth without becoming soggy. Standard toppings include chashu (braised pork belly slices), ajitsuke tamago (marinated soft-boiled egg), kikurage (wood ear mushrooms), benishoga (pickled red ginger), sesame seeds, scallions, and sometimes garlic chips or mayu (black garlic oil).

A defining tradition of Hakata-style tonkotsu is kaedama: diners finish their initial portion of noodles, then order an extra serving (for a small fee) to add to the remaining broth. This practice reflects the regional preference for quick noodle consumption before they soften.

Tonkotsu is distinct from shoyu ramen (clear chicken- or dashi-based broth with soy sauce tare), miso ramen (fermented soybean paste base, associated with Sapporo), and pho (Vietnamese rice-noodle soup with beef or chicken broth). In Los Angeles, tonkotsu ramen has been a defining dish since the 2010s, with Tsujita Annex on Sawtelle Boulevard (opened 2011) widely regarded as the city’s most celebrated version, alongside Tatsu Ramen, Daikokuya, Killer Noodle, and Hakata Tonkotsu.

Dietary notes: Tonkotsu ramen is pork-based and not halal or kosher; it contains gluten (from wheat noodles and soy sauce) and is not vegan or vegetarian. Mayu (black garlic oil) is optional but common.
