Akindo Sushiro Co., Ltd. (Headquarters: Suita City, Osaka; President: Kohei Nii) will begin selling five sushi products and one side menu item, supervised by culinary researcher Ryuji and voice actor Yasuhiro Yasumoto, at Sushiro stores nationwide starting Wednesday, May 20th, in pursuit of further evolution and possibilities for sushi.
This time, products supervised by culinary researcher Ryuji, who is active in many fields to spread the joy of home cooking as the 'big brother of cooking' with a total of 11.3 million followers including social media, and voice actor Yasuhiro Yasumoto, who appears in numerous drama CDs and game works in addition to his narration activities, will be available at Sushiro.
The collaboration started with a video posted on the YouTube channel 'Ryuji's Buzz Recipes' in December 2024. A total of six products were supervised by the two: five sushi items and one side menu item. By combining Sushiro's procurement and product development passion with the specific requests of Ryuji and Yasumoto, and after numerous meetings, a satisfying product was finally completed after about a year of planning.
'Pickled Albacore with Mayo and Lemon Sauce' and 'Pickled Engawa with Lemon Sauce' are refreshing sushi dishes topped with an original 'salt lemon sauce' developed by Ryuji, placed over a bed of aromatic vegetables including shiso leaves, kaiware sprouts, and onion slices. The 'Pickled Albacore with Mayo and Lemon Sauce' has a layer of mayonnaise sauce between the fish and the vegetables, and the richness of the mayo enhances the flavor of the tender albacore. 'Conger Eel with Andes Rock Salt and Lemon' is a dish where grilled conger eel is paired with Andes rock salt and topped with lemon, creating an appetizing plate with a fragrant aroma and the refreshing scent of lemon. The irresistibly junky 'Tuna Natto Garlic Gunkan' features natto and pickled tuna, topped with a generous amount of garlic to deliver the junky deliciousness that is the hallmark of Ryuji's recipes.
Furthermore, 'Ota-Mayo Roll' and 'Fried Potatoes with Ota-Mayo' will also be available, using the 'Otaku no Mayo,' nicknamed 'Ota-Mayo®'—an ultra-rich, guilty-pleasure mayonnaise with flavors of fried garlic, bacon, and black pepper, co-developed by voice actor Yasuhiro Yasumoto and culinary researcher Ryuji. Please enjoy the excellent compatibility with the junky taste of 'Ota-Mayo®'.
