This product is sold on Amazon for 1098 yen per bottle. It's Tsubame Sauce, a local sauce from Kyoto. It's used in okonomiyaki restaurants, kushikatsu restaurants, and also in ordinary households. The size is 500ml per bottle. The label is also cute. The Ori sauce is unusual, I think. It has a thick, spicy flavor, made from the remnants at the bottom of the tank when the sauce is manufactured, and it seems that professionals use it as a key to the flavor. It is made to suit each dish.
