Ikkonka, a Yokohama-style Iekei ramen chain operated by Ishihara Sangyo Co., Ltd., is set to open a new location in Omihachiman, Shiga Prefecture, on September 8, 2026. This marks the company’s third location in the prefecture, following its existing branches in Hikone and Minakuchi.

To celebrate the opening, the restaurant will offer a special promotional item to the first 2,000 customers. These individuals will receive a unique sticker (senjafuda) that grants them permanent free toppings for all future visits to the establishment.
