Using Quail Eggs, a Specialty of Toyohashi! Local Retort Food Packed with the Charm of Local Ingredients

Sankyo Foods Co., Ltd. (Headquarters: Toyohashi City, Aichi Prefecture; President: Toshiyuki Nakamura), a manufacturer and seller of seasonings, dried foods, and processed foods with the catchphrase 'Eating "Wakuwaku" (Excitement) around the world,' is pleased to announce that its locally produced retort food 'Toyohashi Napolitan Sauce' was registered as a new Toyohashi City Hometown Tax donation gift on Wednesday, April 1, 2026.

'Toyohashi Napolitan Sauce' is a retort food manufactured at the company's own factory in Toyohashi City, using an abundance of ingredients from the city under the theme of 'local production for local consumption.' Through this registration, we aim to deliver the charm of Toyohashi to people nationwide through food.

### The Bounty of Toyohashi in One Dish: Commitment to Local Consumption Toyohashi City, Aichi Prefecture, is blessed with a mild climate and vast land, boasting one of the highest agricultural output values in Japan. 'Toyohashi Napolitan Sauce' uses local ingredients grown in this city, such as onions, tomatoes, and quail eggs. Notably, Toyohashi boasts the highest production volume of quail eggs in Japan. This product uses two quail eggs in the sauce, creating a visually appealing and satisfying texture. Additionally, the bacon is made from Toyohashi-grown pork and manufactured within the city. This local Napolitan sauce is a true condensation of 'Toyohashi's Bounty,' with every ingredient selected with care to represent the city.

### Completed After 1 Year and 100 Trials: Aiming for Flavor Beyond Ordinary Retort Food To maximize the natural taste of the ingredients, the cooking process uses a method of simmering utilizing moisture from the vegetables with minimal added water. It features a fragrant, rich taste where the fresh acidity of tomatoes, the sweetness of onions, and the richness of bacon are harmonized. Besides pasta, it can be used for various arrangement menus such as omurice, gratin, and doria.

Development began with the theme of regional contribution and a desire to communicate the charm of Toyohashi through food. Given Toyohashi's mild climate and its status as a major tomato producer, the team decided to develop a Napolitan sauce—a menu that uses plenty of tomatoes and pairs well with noodles in a retort format.

The development period was about one year. Trials were repeated approximately 100 times while identifying flavor changes caused by retort processing. Retort food is difficult because flavors change easily during the heat sterilization process. Therefore, the blend was adjusted while anticipating the post-processing taste, and through repeated prototyping and improvement, a satisfying flavor was achieved. This product is filled with our desire to create a retort food that can be easily eaten at home while clearly conveying the charm of Toyohashi.

### To the Nation as a Hometown Tax Gift With this registration, 'Toyohashi Napolitan Sauce' can now be applied for nationwide through 'Rakuten Hometown Tax.' We hope it will be enjoyed by many, not only for home use but also as a return gift for those who want to support Toyohashi City or enjoy local gourmet food.

Our company will continue to develop local products that introduce the rich ingredients of Toyohashi to more people and contribute to promoting the region's charm.
