京急開發集團的餐飲事業公司京急Royal Foods股份有限公司（所在地：東京都大田區，董事社長：小島賢二）將以新型態加盟模式，於2026年3月31日（二）在神奈川縣川崎市Cittadella大道（川崎市川崎區小川町1-7-4）開設飯糰專賣店「飯糰こんが」。
本次展店是本公司挑戰加盟事業，以開發新業態、擴展事業領域為目的。
【傳承傳說級美味的「不壓製」飯糰】
「飯糰こんが」最大的特色是「不壓製」飯糰，由職人接單後現場製作。
透過不壓碎米飯，如同注入空氣般地包裹，實現了入口即化的鬆軟口感。
【川崎地區的外帶專門店】
新店位於京急川崎站徒步6分鐘、JR川崎站徒步4分鐘的便利地點，為外帶專門店。
可對應通勤、通學時的早餐需求，以及辦公室午餐、晚餐配菜等廣泛的生活場景。將為車站利用者及周邊來訪者提供方便又道地的「微笑食物」。
此外，凡購買任選兩款飯糰，即可享優惠組合價購買「味噌湯」或「漬物」，提供高滿足度的商品組合。
【飯糰こんが的三大堅持】
【米飯】新潟縣岩船產越光米
特點是濃郁的香氣與適度的甜味。炊煮後適度散去水氣，實現米粒飽滿的口感。
【海苔】嚴選有明產海苔
使用香氣濃郁、口感爽脆的海苔，溫柔地包裹著鬆軟的米飯與內餡。
【內餡】20種以上的手作內餡
人氣的「醬油漬蛋黃」是花費3天精心製作的自信之作。從經典到創意口味一應俱全，也可選擇兩種內餡組合的加料方式。
