Hakata-Nakasu Kawabata ramen favorite Ittenmon opens first Tokyo location in Kanda

FOUR SEEDS FOODS EXPRESS, a company operating casual dining businesses, will open Ittenmon, a popular ramen shop originating in Hakata’s Nakasu Kawabata area, in Tokyo’s Kanda district. Ittenmon serves a new style of Japanese-style tonkotsu ramen, blending a flavorful Japanese dashi made generously with Rishiri kombu from Hokkaido with a savory pork-bone soup. The noodles are straight noodles delivered directly from Hakata, while the chashu uses the domestic branded pork Waton Mochibuta for a tender texture and rich flavor. Each bowl features a special spicy green sauce made with yuzu kosho and green chili peppers, adding depth as the meal progresses. The Kanda location will also offer homemade handmade gyoza wrapped in-store daily. Made with carefully balanced domestic pork and vegetables, the dumplings are crisp and fragrant on the outside, moist and juicy inside, with rich meat juices spreading through each bite. The menu also includes yaki ramen, a dish born from Hakata’s yatai street-stall culture, finished with Ittenmon’s special green sauce. It is characterized by the aroma created through quick high-heat cooking and chewy noodles coated in umami. Other beer-friendly dishes, including the long-popular seared scallion chashu, will also be available. Ittenmon Kanda is located at 2-14-3 Kajicho, Chiyoda-ku, Tokyo.
