Main Facts: A Celebration of Poultry
For enthusiasts of authentic Japanese yakitori, the name "Yakitoriya Sumire" has long been synonymous with quality, tradition, and the art of the skewer. As winter hits its peak in Tokyo, the popular restaurant chain—which boasts five strategic locations across Shibuya Ward—has announced a high-value campaign designed to delight both local patrons and food-seeking travelers.
From January 28th through January 30th, 2023, Yakitoriya Sumire is hosting its highly anticipated "Chicken Days." During this 72-hour window, the establishment is drastically reducing the price of two of its signature menu items: the Daisen Chicken Yakitori (a trio of premium skewers) and the Daisen Chicken Karaage Mix. By slashing prices from their standard retail rates to a flat 290 JPY (319 JPY with tax), the restaurant is inviting guests to experience the high-quality, tender, and succulent flavor profiles of Daisen-raised poultry at a fraction of the usual cost.
Beyond this promotional event, the restaurant is simultaneously rolling out a wellness-focused, limited-time menu titled "Edible Yoga." Running from January 28th to February 10th, 2023, this conceptual menu aligns with the growing trend of "functional food," offering dishes designed to restore internal balance through high-protein, nutrient-dense ingredients.

Chronology of the Promotion
The campaign is structured to provide a comprehensive experience for diners, split between the short-term flash sale and the longer-term wellness menu.
- January 28th, 2023: Official commencement of both the "Chicken Days" promotional pricing and the launch of the "Edible Yoga" seasonal menu across all five Shibuya Ward locations.
- January 28th – January 30th, 2023: The core "Chicken Days" window. During these three days, customers can order the discounted Daisen Chicken Yakitori and Karaage Mix. Management has implemented strict terms, including a limit of one plate per group to ensure equitable access to the promotion.
- January 31st – February 10th, 2023: While the flash sale concludes, the "Edible Yoga" menu remains available, allowing patrons a longer window to explore the intersection of traditional yakitori preparation and health-conscious dining.
Supporting Data: The Anatomy of the Offer
Understanding the value proposition requires a closer look at the components of the discounted menu items, which represent the flagship offerings of the Yakitoriya Sumire brand.
The Daisen Chicken Yakitori (3 Skewers)
Usually priced at 698 JPY (768 JPY with tax), the price reduction to 290 JPY represents a discount of nearly 60%. The selection is curated to showcase the versatility of Daisen chicken, a breed prized for its tenderness and flavor. The platter includes:

- The "King’s Liver" (Ousama no Rebaa): A decadent, rich cut that highlights the quality of the sourcing.
- Hinatoro: The shoulder portion of the chicken, known for its unique, juicy texture.
- The Chef’s Choice: A rotating third skewer, allowing the grill master to highlight the best catch of the day. Each skewer weighs approximately 60g, ensuring a satisfying portion for the diner.
Daisen Chicken Karaage Mix (4 Pieces)
The karaage promotion offers a similar value proposition, dropping from 556 JPY (612 JPY with tax) to the same 290 JPY price point. This dish is a masterclass in texture and flavor balance. It utilizes two distinct preparations:
- Breast Meat: Infused with an elegant, savory blend of kelp and scallop extracts.
- Thigh Meat: A bolder profile featuring classic soy sauce, garlic, and ginger aromatics.
By serving both in a single "Mix" platter, the restaurant encourages guests to compare the contrasting flavor profiles and textures of the bird’s anatomy, a practice highly regarded in Japanese culinary culture.
The "Edible Yoga" Philosophy: A Holistic Approach
Perhaps the most intriguing development at Yakitoriya Sumire is the introduction of the "Edible Yoga" menu. Moving away from the typical "pub food" stereotype, this menu frames chicken not just as a savory treat, but as a vehicle for health.
The menu is designed to harmonize the body. By pairing high-protein Daisen chicken with ingredients rich in vitamins and dietary fiber—such as mushrooms, shiso leaves, and mountain yam—the chefs have crafted a menu that feels nourishing. Notable items include:

- Mushroom and Gizzard Al Ajillo: A savory dish emphasizing the health benefits of varied fungi.
- Aromatic Soy Sauce Enoki & Shiso Rolls: A lighter, herbaceous option.
- Homemade Atsuage (Deep-fried Tofu) with Mushroom Sauce: A vegetarian-adjacent protein booster.
- Crunchy Apple Vinegar Sour: A beverage selection designed to aid digestion, rounding out the "yoga" theme.
Official Responses and Operational Guidelines
The management at Yakitoriya Sumire has been transparent regarding the logistics of the "Chicken Days" event to manage customer expectations and maintain high service standards.
Terms of Service:
- Exclusivity: The discounted items are for dine-in customers only. Takeout and delivery services are excluded from the promotion to prioritize the in-house experience.
- Group Limits: To prevent waste and ensure that the discounted ingredients are distributed to as many guests as possible, the offer is limited to one plate per group.
- Stacking Policies: The promotion cannot be combined with existing loyalty programs, external coupons, or other seasonal discounts.
These rules reflect the restaurant’s commitment to sustainable business practices during high-traffic promotional periods. By limiting the volume per table, they ensure that the kitchen staff can maintain the precision required for high-quality charcoal grilling.

Implications for the Shibuya Dining Scene
The success of campaigns like "Chicken Days" highlights the evolving nature of the Japanese izakaya (pub) culture. Historically, these establishments were strictly focused on providing a place to drink and eat casual fare. However, Yakitoriya Sumire is signaling a pivot toward "value-driven gastronomy."
Economic Impact
For the consumer, this event offers a low-barrier entry point to high-quality ingredients. By subsidizing the cost of premium Daisen chicken, the restaurant effectively lowers the psychological price barrier for new customers. It is a calculated marketing move that increases foot traffic during the traditionally slower post-holiday period of late January.
Culinary Trends
The "Edible Yoga" menu is particularly significant. It demonstrates that even within the niche of a chicken specialty restaurant, there is room for health-conscious innovation. The inclusion of ingredients like mountain yam and apple vinegar indicates that the brand is listening to a younger, more health-conscious demographic that demands more than just deep-fried items.

Community Presence
With five locations across key hubs—Dogenzaka, Miyamasuzaka, Yoyogi-Uehara, Sasazuka, and Hatagaya—Yakitoriya Sumire is cementing its status as a local staple. These locations serve as community anchors, and by offering these promotions across all branches simultaneously, the brand ensures a consistent experience regardless of which neighborhood a diner chooses.
Conclusion: A Must-Visit for the Discerning Eater
For those living in or visiting Tokyo, the late-January window offers a rare opportunity to engage with high-tier Japanese cuisine at a price point that is almost unheard of in the current market. Whether one is drawn by the allure of the perfectly grilled "King’s Liver" or the conceptual novelty of "Edible Yoga," Yakitoriya Sumire has positioned itself as an essential stop on the Shibuya culinary map.
The combination of rigorous ingredient sourcing, traditional grilling techniques, and a modern, health-forward menu strategy proves that Yakitoriya Sumire is not merely resting on the popularity of chicken. Instead, they are actively refining the dining experience, one skewer at a time. As the "Chicken Days" promotion approaches, it is highly recommended that patrons secure their seats early at one of the five locations to avoid disappointment during this brief but impactful celebration of Japanese poultry.
