Marugame Seimen Launches Seasonal 'Onioroshi Series' Nationwide on June 2, 2026

Marugame Seimen, the Sanuki udon specialty chain known for its focus on handmade, freshly-made noodles, is launching its most popular summer menu, the 'Onioroshi Meat Bukkake Udon,' nationwide starting June 2, 2026, primarily at roadside locations. This dish features crisp, coarse-grated daikon radish and freshly grilled beef. On the same day, the chain will also roll out the 'Onioroshi Pork Shabu-shabu Bukkake Udon' and 'Onioroshi Fried Chicken Bukkake Udon' at all locations, including those in shopping centers and tenant buildings.

With severe summer heat predicted nationwide, the 'Onioroshi Series' offers a 'hearty yet refreshing' dining option for days when appetites may wane. Customers can choose from three varieties: the classic beef version, the pork shabu-shabu version featuring soft, chilled pork marinated in special dashi, or the fried chicken version, which is carefully fried in-house to be crispy on the outside and juicy on the inside.

As every Marugame Seimen location functions as a noodle workshop, they use 100% Hokkaido wheat to prepare noodles from scratch and serve them immediately after boiling. The chilled udon is rinsed to ensure the signature smooth texture and firm chewiness.
