Yamadori's Noodle Champion Contest Showcases 53-Year-Old Broth with Summer Delight
Yamadori Corporation to Debut at The Noodle Grand Prix in Tokyo 2026
Yamadori Corporation, a renowned food manufacturer based in Kuwana City, Mie Prefecture, is making its first appearance at the 7th Noodle Grand Prix in Tokyo 2026, set to take place on May 16-17 at Komazawa Olympic Park. The company was the pioneer of straight broth, introducing the first straight noodle soup in Japan back in 1973. Their signature product, the Nadai series, has been a beloved staple for 53 years.
As the temperature across Japan soared to over 25 degrees in April, discussions intensified about the increasingly hot summers, especially after the Japan Meteorological Agency labeled days with temperatures above 40 degrees as "extreme heat days." This summer heat has inevitably raised interest in home cooking, as more people choose to stay indoors to avoid the heat. With this backdrop, Yamadori as a pioneer in straight broth is excited to present their recipe for a summer refreshing dish.
Yamadori's entry for the Noodle Grand Prix is titled "Charred Mackerel Noodle, Inspired by 53 Years of Nadai Broth". This dish, lovingly crafted by the company's employees, captures the richness of their history and expertise. The combination of charcoal-grilled mackerel, tororo (grated yam), okra, natto, and a soft-boiled egg all brought together by the flavorful Nadai broth creates a satisfying meal perfect for scorching hot days. Priced at 500 yen (tax included), attendees will receive a recipe booklet to recreate this dish at home.
In addition to the delicious taste, the Charred Mackerel Noodle is commendable for how easily it can be replicated at home—especially during hot summer days when you prefer to minimize time spent in the kitchen. By using precooked noodle packs that only require rinsing with water and ready-made mackerel and frozen okra from convenience stores, you can avoid using heat altogether. With Nadai broth on hand, success is guaranteed. We encourage you to chill your Nadai broth for an even more refreshing taste during these hot months.
On the day of the event, attendees will also have the opportunity to vote for their favorite dish. Please come and support "Charred Mackerel Noodle" at the Noodle Grand Prix!
