Jinenjo in Saitama: Rokurinsha's Tsukemen Cousin With Noodles the Size of Udon

Jinenjo Tsukemen — A Detour Worth Taking

Jinenjo tsukemen (dipping ramen) isn't going to reinvent anything for you, and that's kind of the point. This is a shop out in Konosu, deep in Saitama (north of Tokyo), that most people without a car are never going to find themselves near.

But it's home to some of the thickest noodles I've come across, closer to udon than ramen, and that alone makes it worth the detour. Sometimes going deep for a bowl means going somewhere nobody's going to stumble into by accident.

The Rokurinsha Connection

The shop opened in 2006 as an offshoot of Rokurinsha. Yes, it's that Rokurinsha, the one with the permanent line on Tokyo Ramen Street at Tokyo Station.

The founder trained there before setting up on his own out in Konosu, and the lineage shows: the same idea of a thick, rich pork-and-seafood dipping sauce, and the same commitment to noodles that don't play around.

The Noodles Are the Whole Reason to Go

The noodles are really the reason to go. They're cut absurdly thick — closer to udon than anything you'd normally call a ramen noodle. They're made fresh daily with a mix of domestic wheat and whole wheat flour.

They're chewy in a way that makes you slow down, which is sort of the whole appeal of tsukemen to begin with — you're paying real attention to the noodles as you work your way through them. At this size, "work" is the operative word.

The Dipping Sauce

The dipping sauce is the story you'd expect if you've had Rokurinsha or anything else in that circle. It's thick, fish-forward and with a pork bone base. It's a style that's common enough that it won't shock you if you've eaten around Tokyo.

I went in expecting exactly what I got, which is fine. I'd say the noodles are the differentiator here, not the broth.

Worth Ordering: The Spicy Ball Add-On

One thing worth calling out: there's an add-on — a spicy ball you drop into the dipping sauce, served on a shiso leaf. It's a good way to shift the flavor partway through the bowl if the richness starts to feel one-note.

Getting There

Jinenjo (次念序) also has a spot on Tabelog's Top 100 (Hyakumeiten) ramen list for East Japan. So it's not exactly a secret among people who take this seriously. It's more that the location keeps it off most people's radar.

If you're driving through Saitama and want a legitimate reason to detour, this is one.
