Understanding JASPO Football Shirts: Are They Original?

If you're diving into the world of collecting football shirts—especially from Japan or the broader Asian market—you’ve probably come across the term JASPO. But what exactly does it mean, and how do these shirts differ from the ones you’re used to seeing from Europe or the US?

What is JASPO?
JASPO stands for Japan Amateur Sports Promotion Organization. It’s a standardized sizing system used in Japan for sportswear. While Western countries use size tags like S, M, L, XL, the JASPO system typically uses a two-number format—like O-XO, M-L, or SS-S—to indicate the range of fit.

The Main Difference of JASPO shirts:

  1. Sizing Format

    • JASPO uses dual sizing (e.g., O-XO), representing a size range rather than a fixed size.

    • These sizes often run smaller than EU/US sizes, so a JASPO “L” might feel like a “M” in Western standards.

  2. Fit and Cut

    • Japanese shirts are usually more tailored and fitted, reflecting local preferences.

    • Sleeves may be shorter, and the body cut more streamlined.

  3. Labeling and Tags

    • Official JASPO shirts carry unique sizing labels in Japanese. These tags can help verify authenticity.

    • Some include additional details like manufacturing origin (Made in Japan or Thailand).

  4. Collectibility

    • JASPO versions of football shirts (especially for the Japan national team or J-League clubs) are often region-exclusive, making them highly sought after by collectors globally.

 

JASPO football shirts are a perfect example of how regional standards can influence sizing and fit. Whether you're a collector or a casual fan, understanding these differences can help you make smarter purchases—and maybe even land a rare gem in your collection. Also, you have to always remember that JASPO shirt is original since it has official license from the apparel and club/country to produce football shirts within Japan or Asia market.
