Omi chanpon is Shiga’s homegrown noodle dish, born at a Hikone noodle shop in the 1960s and now the prefecture’s definitive everyday comfort food. Unlike its rich, pork-boned Nagasaki namesake, the Omi version rests on a delicate golden broth of kombu and bonito — closer to refined udon dashi — over which a mountain of stir-steamed cabbage, bean sprouts, onions and pork is piled onto springy medium noodles, and the local ritual is to douse the last third with a swirl of vinegar, which brightens the whole bowl.

Tips
Do as locals do: eat the first half as served to taste the dashi’s delicacy, then add vinegar — the transformation is the dish’s signature move, and tables always carry a bottle. It’s also one of the cheapest good meals in the castle towns, making it the ideal quick lunch between Hikone’s keep and Genkyuen garden.
