Mujaki Foods Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative Director and President: Hayao Tashiro), which operates the restaurant startup support service "Toranavi," will host a specialized seminar "Summer Sales Slump Breaking Strategy" for ramen shop owners and aspiring restaurant entrepreneurs on Monday, June 29, 2026, at Ebisu Garden Place Tower.
■ The "Summer Slump" in the Ramen Industry Caused by Extreme Heat: Changes in Consumer Behavior Seen Through Data
Recent record-breaking intense heat in Japan poses an extremely serious challenge for restaurant management, especially in the ramen industry. In the general dining market, data clearly shows a strong correlation where demand for hot menu items sharply decreases when the maximum temperature exceeds 30°C (midsummer day), while demand for cold beverages and noodles expands. Particularly in ramen shops, even with thorough temperature control inside the store, psychological and physiological factors—where consumers avoid "perspiring from going out" and "body temperature rising from hot soup"—strongly influence behavior. This leads to a notable "summer slump" where customer numbers steadily decline in proportion to rising maximum temperatures.
Household surveys by the Ministry of Internal Affairs and Communications also confirm a significant drop in spending on instant noodles and restaurant ramen during summer compared to other seasons. How to overcome this "seasonal demand trough" is the biggest turning point that determines the survival of small-scale restaurants and independent establishments. Many on-site efforts are limited to temporary symptomatic treatments like "introducing chilled menu items," but what is fundamentally needed is to build a "customer attraction structure" that doesn't use the heat as an excuse, and to transform this season into an opportunity for maximum profit through seasonal management strategies and marketing methods.
■ "Winning Opportunities in Summer" and Customer Attraction Know-How Derived from Over 30,000 Bowls of Experience
Even under these tough conditions, successful shops that continue to attract customers, or even garner overwhelming support in summer, have common strategies. In this seminar, Hiroshi Osaki, Chairman of Ramen Data Bank Co., Ltd. and known as the man who has eaten the most ramen in Japan, will be invited as a special lecturer.
As of the end of November 2025, Mr. Osaki has completed over 30,500 bowls of ramen, accumulating vast data on the rise and fall of ramen shops nationwide. Beyond merely introducing trends, he will thoroughly explain, based on facts, the "customer attraction structure" common among successful shops that maintain their customer base even in extreme heat, and the reasons why consumers seek "that one bowl" despite the heat. He will present concrete guidelines for evolving into an overwhelmingly successful shop from the perspectives of restaurant attraction, sales improvement, and branding.
■ For Those Aspiring to Independently Open or Expand Shops: Public Disclosure of a "Zero-Capital Startup" Scheme Without Risk
The latter half of the seminar will provide a detailed explanation of the "Toranavi" system, which enables aspiring restaurant owners who are anxious about funding to achieve independent startup with zero personal capital and no debt. The company will impart a specific scheme where they fully cover property acquisition and equipment investment for artisans who have "passion and skill but no funds." On the day, in addition to successful case studies, the actual profit and loss statements of shops utilizing Toranavi, which are usually confidential, will be exclusively disclosed, clarifying the roadmap for owning one's own shop in the shortest possible time.
