Ramen is alkaline wheat noodles in a slow-built broth, finished with toppings that vary by regional style. The defining technical feature is the noodle itself — wheat dough treated with kansui (alkaline mineral water), which gives ramen noodles their characteristic yellow color, springy chew, and distinct smell. Without kansui, you have lo mein. With kansui, you have ramen.
The broth is the second technical pillar. Real ramen broth is built over hours from bones, sometimes from a mix of pork, chicken, and seafood, often with vegetables and aromatics. The result is layered, deep, and structurally different from any clear soup.
Ramen organizes by tare (the seasoning base added to the bowl before broth):
A fifth modern category, gyokai (魚介) — fish/shellfish-forward — has emerged in Japan since the 2000s.
Beyond the four classics, ramen has split into dozens of regional styles:
Ramen is deeply savory, often rich, sometimes salty-bright (shoyu) or full-bodied creamy (tonkotsu). Spice is style-dependent — most ramen is mild; tantanmen and Buldak-style variants run hot.
The two share a name root but are fundamentally different dishes — see the full comparison. Quickly: ramen is fresh shop-made; ramyeon is instant. Ramen is slow-built broth; ramyeon is seasoning-packet broth. Ramen is mild by default; ramyeon is spicy by default.
The US ramen scene has matured dramatically since 2010. Top US ramen shops:
Look for shops that use Sun Noodle fresh noodles — the LA-based supplier most US ramen shops rely on.
For US home cooks, two paths:
Path 1: Premium instant. Buy Sun Noodle fresh ramen, build a quick broth from chicken stock + dashi + miso/soy/salt. 20 minutes. Good ramen, not great.
Path 2: Full scratch tonkotsu. Pork bones, 12+ hour boil at rolling temperature (different from gentle pho simmer — ramen broth WANTS the agitation). The result is restaurant-quality ramen at home — but it's a project.

In Japan, slurping noodles is good manners — it signals you're enjoying the food and cools the noodles as you eat. In the US, the cultural default is the opposite. Slurp anyway. Japanese ramen is designed to be eaten quickly while still hot, and slurping is part of the technical practice.
