1. The Beginning of the Story: The 7 AM Queue and the "Reverse O2O" Phenomenon

At the time when the mountains of Ina Valley are shrouded in morning mist, a queue has already formed in a corner of the shopping street. The target is a small Japanese confectionery shop's "Ina no Mayu."
People who couldn't buy it online due to "instant sellouts" flock to the location thinking "maybe I can buy it in person," creating a **"Reverse O2O"** flow from the net to the real world.

• The Reversed Charm of "Being Able to Buy Because It's Local"

• "Standing in Line" Becomes an Experience and a Material for SNS Posts
  At this moment, the product is elevated from just "taste" to a "travel purpose."
  
  

2. The Birth Secret: The Showa Challenger's Wish Entrusted to the Cocoon

• In the 1950s, the predecessor of Echigoya Confectionery was exploring "new Japanese sweets."

• Whipped cream in monaka skin, covered with chocolate on the outside—too innovative for Ina at the time.

• Inspired by the region's thriving sericulture, it was shaped like a cocoon (mayu) and named "Ina no Mayu."

• The price was kept around 150 yen per piece, surviving as a "local staple souvenir."

• Due to constraints like low-temperature storage and shelf life, it was more suited for face-to-face sales than mass distribution.
  
  
  

The "Seeds of the Story" Were Embedded from the Start
Elements that would be re-evaluated in the SNS era were hidden: regional history (sericulture) x handcraft x simple pricing.

3. The Moment of Viral Ignition: What Happened with Just One TikTok

In the spring of 2025, **food review TikTok creator "Neet Girlfriend with a Big Attitude"** introduced it in a video.

• ASMR (chewing sounds) + close-up of the cross-section to appeal the "triple texture."

• Comment section → secondary spread → chain of hashtag posts.

• #Ina no Mayu posts reached thousands, with total views estimated to exceed 100 million.

• On X (formerly Twitter), posts about "sold out in 5 minutes" and "couldn't buy" promoted FOMO.
  
  

Key Points

1. The "appearance and sound" of the video induced purchasing desire

2. A pathway existed for immediate purchase after viewing (online sales)

3. The experience of not being able to buy also became material for spreading, strengthening scarcity
   
   

4. The "5-Minute Sellout" Mechanism: Scarcity x Visual & Auditory Appeal x FOMO

4-1. Scarcity

• Due to handcrafting, the physical limit is 2,000 to 3,000 pieces per day.

• Clearly insufficient to meet nationwide demand ⇒ "instant sellouts" became the norm.

4-2. Visual & Auditory Appeal (ASMR & Visual Hook)

• Oval shape, glossy chocolate, and white cream cross-section.

• The memorable silhouette of a "cocoon."

• Chewing sounds create a taste image in the brain.

4-3. FOMO (Fear Of Missing Out)

• Posts of both "could buy/couldn't buy" fueled the spread.

• "Limited sale times" served as both a bot countermeasure and a scarcity performance, increasing those waiting to reload.
  
  

5. The Response of the Long-Established Store: Online Suspension, Midweek Closures, and the Behind-the-Scenes of Increasing Artisans

• Temporary suspension of online and phone orders: Focused on in-store handling to suppress confusion.

• Changed regular holidays to Wednesday and Thursday for a two-day weekend: Ensured production and staff rest.

• Increased artisans and division of labor: Shared quality standards by dividing tasks into baking, filling, coating, and packaging.

• Improvement of sales UX: Distributed numbered tickets, randomized sales times, and implemented anti-resale measures.
  
  

Prioritizing "Continuing Mechanisms" Over "Selling Quantity"
The decision to avoid burnout, fatigue, and quality decline was more important than selling out quickly.

6. Money Dropped in the Region: The Microeconomic Effects of the Queue

• Hotel occupancy rates, restaurant sales, and taxi demand increased.

• The tourism association is considering a **"Mayu Passport"** type project and organizing a tour route.

• Data shows that about half of the visitors are from outside the prefecture, with a few percent being inbound tourists.

• On the other hand, there are voices from local residents about "not being able to buy" and "traffic jams,"posing a challenge for coexistence with residents.
  
  

7. Pros and Cons and Sustainability: Three Keys Looking Beyond the Boom

7-1. Preserving Quality and Handcrafting

If taste declines with increased production, it will immediately cause a SNS backlash. **"The Courage Not to Increase"** is also a strategy.

7-2. Controlling Expectations

To prevent disappointing posts like "wasn't worth the wait,"

• Clearly explain size and taste in advance

• Present best practices for storage and consumption (chilled/room temperature)
  
  
  
  

7-3. Turning Customers into Repeaters: Expanding "Experience Value"

• Workshop tours/packaging experiences/live manufacturing broadcasts

• Instead of seasonal exclusives, motivate revisits with "sequels to the story" (regional cultural experiences)
  
  

8. Japanese Influencer Marketing Techniques x Overseas Comparison

• Japan's Unique Cultural Capital: "Queues are Value," "Exclusivity is Justice"

• The randomness of TikTok → even small businesses can become nationwide hits if they "hit"

• However, be cautious of advertising regulations like the Act against Unjustifiable Premiums and Misleading Representations and the Pharmaceutical Affairs Act (especially in beauty and health fields)

• Overseas, "D2C x Live Commerce" is advancing with immediate payment pathways, but Japan still has many divisions
  → Small stores should simultaneously design "presentation + ease of purchase"
  
  

9. The Culture Symbolized by the "Cocoon": Memories of Sericulture and Rebranding

• Cocoon = Symbol of Life's Regeneration/Transformation.

• As sericulture culture fades, confections become a "reconnection device" for culture.

• Resonates with overseas users in the context of retro revival x nostalgia marketing.

• By translating regional history into product stories, it also impacts tourism value.
