Kani Zanmai is offering an all-you-can-eat eel buffet featuring sushi, fried items, and dessert through July 26 [1].
The promotion coincides with the traditional Japanese custom of eating eel during the hottest days of summer to maintain stamina. By providing a high-value buffet, the restaurant aims to attract new diners and help existing customers cope with the summer heat.
Nagao Hideki, an area manager for Kani Zanmai, said the buffet was started because of a desire for customers to feel energized during the hot summer period [1]. The restaurant has seen a significant increase in new guests specifically seeking the eel offer, and Nagao said new customer visits have risen by 15% to 20% [1].
The cost for the Kani Zanmai buffet is 4,378 yen, including tax [1]. One couple in their 50s mentioned the value of the meal, noting that the price of 3,980 yen before tax felt like a good deal [1].
While Kani Zanmai promotes this specific offer, other reports indicate similar seasonal promotions across the industry. For example, a different restaurant chain, Iroha Nihon-eto, is reported to offer an eel buffet at a lower price point of 3,500 yen, including tax [2, 3].
The limited-time promotion at Kani Zanmai is scheduled to conclude on July 26 [2], the day before the traditional Day of the Ox, a peak date for eel consumption in Japan.
“I started the all-you-can-eat eel because I want customers to feel energized during the hot summer period.”
The introduction of all-you-can-eat eel buffets reflects a competitive strategy to capture the seasonal demand surrounding the Day of the Ox. By leveraging a perceived increase in supply or lower procurement costs, restaurants are using high-value, limited-time offers to convert traditional seasonal demand into a mechanism for acquiring new customers.
