1. Who is 551 Horai? The Magic of "At That Time!" That Even Attracts Japanese

Since its founding in 1945, 551 Horai has adhered to the principle of **"hand-wrapping each piece and providing it freshly made,"** and now sells hundreds of millions of pieces annually in the Kansai region as a "soul food." According to the official FAQ, everything from shaping to steaming is done entirely by hand, with no preservatives used.551horai.co.jp

2. The Shock of the Notice: From SNS Spread to International News

In April 2025, a photo of a sign saying "Up to 50 pork buns per person" posted at the Osaka Airport South Terminal store was viewed over 13 million times on X, causing a stir among netizens worldwide with comments like "Who buys that many?"1,300万回以上表示j-town.netameblo.jp

3. The Honest Truth Behind "Up to 50 Pieces"

A public relations representative explained, "It's common for customers to buy 10 to 20 pieces. The balance between fairness and production capacity is 50 pieces," while also expressing the desire to "ideally have no limit."encount.press

• Fairness: Since handmade products may not meet demand, subsequent customers might not be able to buy, leading to complaints.

• Psychological Limit: The number 50 is close to "almost unlimited" but functions as a deterrent.

• Store Circumstances: Limitations may be lowered if there are fewer staff or steamers.encount.press
  
  
  
  

4. Handmade Process and the "Wall of 140": The Reality of Supply Capacity

The maximum number that can be steamed at the store at the same time is about 140. Orders exceeding this require waiting time or reservations. The physical capacity of the steamer and the management of dough fermentation are bottlenecks.datazoo.jp551horai.co.jp

5. Kansai's Bulk Buying Culture and the "Souvenir Economy"

In Japanese business and family events, the **"gift-giving culture"** is deeply rooted, and 551 is commonly used as "frozen stock for breakfast or a late-night snack."

• Distribution Souvenirs: 10 pieces × 5 boxes = 50 pieces is a realistic quantity for workplaces or club activities.

• Regional Identity: The "When there's 551~♪" commercial is a nostalgic ad for Kansai people.

• Frozen Storage: The taste doesn't deteriorate easily, and reheating with a microwave and steamer provides a high reproduction rate.j-town.net
  
  
  
  

6. Resale, Food Loss, Airport Security... Three Factors Influencing Quantity Limits

1. Preventing Resale: To curb cases of high-priced resale on flea market apps.

2. Food Loss: To prevent waste from unauthorized cancellations after large orders.

3. Airport Security and In-flight Odor: On international flights, products with strong odors may be subject to restrictions.
   Due to different circumstances at each store, the upper limit may be temporarily lowered.encount.press
   
   
   
   

7. Comparison with Overseas "Portion Culture"

Using examples like America's "Costco pizza one whole = one family portion" or Taiwan's "takeout of 50 xiaolongbao," Japan's "bulk buying" is surprising in quantity but unique in its social role of **"distribution."**

8. Traveler's Guide: How Not to Fail in Bulk Buying & Bringing Back

• Advance Reservation: For 50 or more, phone reservation is recommended.

• Method of Bringing Back: Use a cooler bag + ice packs to maintain temperature for 2-3 hours.

• International Flight Users: In some countries like the U.S., there are restrictions on bringing in meat products, so declaration is necessary.

• Customs Declaration Form: Writing "pork bun, fully cooked, personal consumption" in English will ensure smooth processing.
  
  
  
  

9. Method to Recreate Store Taste with "Freezing → Re-steaming"

The official site recommends reheating by "steaming for 10 minutes." If using a microwave, cover with a water-moistened kitchen paper to prevent the skin from drying out.551horai.co.jp

10. The Future of 551: DX, Inbound, and the Concept of "Freshly Made Anywhere"

In recent years, Horai has been trialing automatic steamers in station areas and frozen vending machines. With the recovery of inbound visitors expected in 2025, demand is expanding again, and there are plans to invest in DX such as "increasing steamers in airport stores" and a "QR order system."
