The oil used at Tonbo is carefully selected and healthy. We are confident in serving this product, even in today's health-conscious society. Although we cannot disclose the details, the base oil is high in linoleic acid and oleic acid. The oil used has a mild aroma and is healthy even when drunk as is. Compared to the currently popular soy sauce-based ramen, Tonbo's abura soba has only about two-thirds the calories because it does not contain soup, making it a great choice for women and those concerned about calories.

The "Kaeshi (sauce)" prepared at "Tonbo" is a blend of several types of soy sauce. We also take care not to impair the original flavor of the soy sauce during the preparation process. When customers mix the noodles, they can enjoy the mellow aroma of the original soy sauce. In addition to the soy sauce, we also add various other flavors as secret ingredients, so that you can enjoy the umami of these ingredients directly without using soup.

Tonbo's noodles are specially made after careful consideration of thickness, curl, and flour, and thorough research into their compatibility with the sauce. The noodles are "medium-thick" and are thick enough to stand up to the sauce, but not overpower it. The curl is just right to blend with the sauce and oil, and also to lift them up. The wheat is blended from several varieties to maintain a good balance with the sauce, without being too overpowering. The more you chew, the more the wheat aroma wafts, and the noodles are custom-made with careful calculations to ensure that the synergistic effect with the sauce brings out the deliciousness of abura soba.
