A truck driver opened a ramen shop in southern Yokohama in 1974 and combined two things nobody had combined: pork-bone broth from Kyushu and soy-sauce seasoning from Tokyo. Every one of the thousands of shops that copied him puts the character for "house" in its name.
In 1974 Yoshimura Minoru, who had been driving long-distance trucks, opened Yoshimuraya in Shin-Sugita, in the industrial south of Yokohama. He had eaten tonkotsu — cloudy pork-bone broth — in Kyushu, and shoyu ramen in Tokyo, and he could not see why the two should be separate.
What came out was tonkotsu-shoyu: pork bone boiled hard until it emulsifies, then hit with dark soy and a slick of chicken fat. Onto that go thick, short, straight noodles — the opposite of the thin curly noodles most shops used — with boiled spinach, sheets of nori, and a slab of chashu.
Yoshimura trained apprentices and let them open their own shops. Nearly all of them ended their names in -ya, written with the character 家, meaning house. Ramen writers started calling the whole lineage ie-kei — "the house line."
It is now one of the largest ramen genres in Japan, with shops in every major city and a permanent presence in student districts. And it is the only major ramen style that can be traced to one man, one address and one year.
Order by giving three settings: noodle firmness, oil level, seasoning strength. "Katame, abura ōme, futsū" is the default of the faithful.
A proper ie-kei shop will ask you three questions, or hand you a card. Men no katasa — noodle firmness: katame (firm) is what regulars say. Abura no ryo — fat: ōme (more) if you want the full thing. Aji no nosa — seasoning: futsū (normal) is correct until you know better.
Then: take a sheet of nori, dip it in the broth until it goes soft, wrap it around some rice, and eat that. Rice is not a side dish here — it is part of the design, and in many shops it is free at lunch.
The Shin-Yokohama Ramen Museum, opened in 1994, is a basement built as a Tokyo street in 1958 — the year instant noodles were invented — with a handful of famous regional ramen shops brought in from around the country. Every shop sells a half-size bowl so you can eat three or four in a sitting.

Order katame, abura ōme, futsū. Then dip the nori, wrap it round the rice, and eat that — it is the point.
A Yokohama ramen style created at Yoshimuraya in 1974: emulsified pork-bone broth seasoned with dark soy sauce, thick straight noodles, spinach, nori and chashu. It is named for the character 家 ("house") that nearly every shop in the lineage puts in its name, and it has spread to thousands of shops nationwide.
You are asked three things: noodle firmness (katame for firm), oil level (ōme for more), and seasoning strength (futsū for normal). Then dip a sheet of nori in the broth until it softens, wrap it around rice, and eat that — the rice is part of the design, not a side dish.
