In a delicious collaboration set to delight food enthusiasts, Russian Sato, the renowned Japanese eating YouTuber, has teamed up with the Yamanashi-based food manufacturer Ajiken to create a standout product: 'Kotteri Rich.' Launching on June 4, 2026, at the OTEMOTO Store, this innovative range features two distinct sauces—grilled meat marinade (yakitori no namadare) and sukiyaki sauce (sukiyaki no namadare). This project, developed under the OTEMOTO Project spearheaded by Russian Sato, focuses on curating an exceptional culinary experience utilizing modern platforms like YouTube, social media, and e-commerce.
The key goal of 'Kotteri Rich' is to maximize satisfaction in every meal. The sauces offer a unique taste that stands out right from the first bite, thanks to meticulous engineering that emphasizes the use of premium ingredients. This concept ensures that the resulting flavors provide not only taste but a fulfilling dining experience. The innovative non-heating 'raw' method employed by Ajiken contributes to the optimal aroma and deliciousness that fans have come to expect.
Targeting an audience predominantly aged 40 to 50, many of whom prioritize satisfaction and peace of mind over sheer quantity, Russian Sato has designed the product while keeping in mind his viewers' feedback. The result is a harmonious balance of delightful indulgence with a quality that can be relished at daily meals.
Reflecting on his roots, Russian Sato has infused the rich food culture of his homeland, Shimane Prefecture, into 'Kotteri Rich.' It features locally-sourced ingredients such as re-brewed soy sauce (Morita Soy Sauce), chili pepper Orochi's claws (Yoshida Furusato Village), and Izumo chiden sake (Yoneida Sake Brewery). Not just the flavor profile, but the product design, including packaging and concept, has been personally directed by Sato himself.
Ajiken, the partner manufacturer, is known for its commitment to producing additive-free products and emphasizes the 'raw sauce' technique. Russian Sato made several visits to Yamanashi for sampling and adjustments, ensuring each layer of the flavor is just right for the customers. Post-launch, he plans to enrich the audience's experience with recipe content shared via his YouTube and social media channels, continuously nurturing the product with customer interactions.
Looking ahead, the OTEMOTO Store will carry out test marketing for 'Kotteri Rich.' Future efforts will encompass:
- - Creating engaging content on YouTube and social media,
- - Hosting pop-up events to let customers sample the products,
- - Gathering user reviews to enhance the product further,
- - Expanding sales channels to local souvenir shops and retail establishments.
The OTEMOTO Project, initiated by Russian Sato, will continue to harness social media, e-commerce, and events for developing and marketing products. Interested producers, municipalities, and businesses in regional branding, new product development, or promotion are encouraged to reach out for collaboration.
