We go behind the scenes of the development of 'Ryuji's Supreme Osechi 2026', created by culinary researcher Ryuji! We fully reveal the new menu trial production of the immensely popular Osechi, which sells out early every year. From ingredient selection to seasoning, and quality checks after freezing and thawing, we introduce the meticulously crafted Osechi manufacturing process and the untold stories of development filled with the passion of Mr. Ryuji and the head chef.
