Ryosuke Oka

Career Executive Chef Ryosuke Oka leads HOSHINOYA Tokyo through Nippon Cuisine, with the work shaped by close attention to Japan’s culinary past. As he developed dishes in the city, the Edo-era sankin-kotai system became a key reference point, broadening both the geography and the time frame of the food. From there, the dinner course moved beyond a single plate and into a course meal that reads regional food cultures with clarity and purpose.

The Essentials Nippon Cuisine: Gourmet Collection is the signature format here: a dining experience that reflects Edo food culture while paying homage to high-quality ingredients from across Japan. The project treats history as something active rather than fixed, using the table to reinterpret older forms without flattening them. French technique is part of the framework as well, adding structure to the way flavor and sequence are built. “I have been studying French cuisine a little, and by incorporating that, I want to present it in a form that is easy for people visiting the restaurant now to interpret and enjoy as delicious.” The method is disciplined, not decorative: familiar references are tightened through technique so they read clearly for contemporary diners. Locality carries equal weight with historical reference. “I am working on this meal with the idea that we can create dishes that can only be made locally.” That principle gives the meal its specificity. Regional identity is not used as garnish; it is the basis of the work, tying the plate to ingredients, setting, and the food culture of Japan. The guiding idea is modernization, not nostalgia. “I think we can make something that modernizes what the chefs of Edo were doing back then.” The line defines the approach: study the old forms closely, then translate them into a present-tense meal that stays grounded in craft and readable in service.

Signature

Ryosuke's signature dishes include Nippon Cuisine: Gourmet Collection and Lost Flavors of Japanese Home Recipes. Together, they map the range of his kitchen language: one shaped by Edo-era ideas and regional ingredients, the other centered on the quiet register of Japanese home cooking.
