Korean-style Chinese food in Japan. That sums up Jyajyan House in Okubo.
Okubo is Tokyo's Korea-town, for those out of the loop. But like the Yokohama China-town, it has taken on an uber-touristy feel. With the boom of K-pop fandom in Japan (I'm looking at you mid 30s to 50s Japanese housewives!) the place is a bit of a madhouse these days. I'm talking fleets of tour buses at noon on a weekday.
There are plenty of Korean staples. Yakiniku, bibimbap, and chijimi shops along the whole block. There are even a few places to get ramyeon, that Korean cousin of ramen.
Most Korean noodle spots here use instant noodles. Not interested.
Apart from the kimchi, this isn't very Korean***. True to the sign on the shop's door, this is Chinese with a Korean twist. The noodles are hand made on site, lamein style.
***I shouldn't make assumptions about Korea, since I know very little about noodle culture there. According to a reader's comment, this combo is quite common in Korea, and is maybe the quintessential Korean-Chinese noodle dish.
Probably the number one item on the menu is the double plate of jyajyamen and champon. The champon is chock full of strange seafood bits. Strange by a Western standard. But, remember, this is Korean-style Chinese food in Japan. That's a lot of east.
And, they deliver.
