Cash is still common, but cashless is growing
Five years ago, most stadium vendors were cash-only. That's changing fast. Most NPB and J-League stadiums now accept some form of cashless payment, but coverage varies by vendor.
What works where
IC cards (Suica / Pasmo / ICOCA)
These transit cards work at most food stalls and merchandise shops in major stadiums. Load one at any train station and tap to pay. This is the most reliable cashless option at stadiums. Apple Pay and Google Pay with a linked Suica also work.
Credit cards
Visa and Mastercard are accepted at official team shops and some larger food vendors. Smaller stalls inside stadiums may not accept them. Don't rely on credit cards alone.
QR payments (PayPay, Line Pay)
Widely accepted at Japanese stadiums, but these apps require a Japanese phone number to set up. Not practical for short-term tourists.
Stadium-specific notes
ES CON Field: Almost fully cashless. Most vendors accept IC cards and credit cards. Tokyo Dome: Mix of cash and cashless. Major vendors take IC cards. Koshien: Many vendors are still cash-preferred. Bring yen. PayPay Dome: Good cashless coverage with IC cards.
Practical advice
Bring Β₯3,000-5,000 in cash as backup. Load your Suica/Pasmo with at least Β₯2,000 before arriving at the stadium. This covers food, drinks, and small purchases without worrying about which vendor takes what.
Where to get an IC card
Buy a Suica or Pasmo at any JR or metro station. The Welcome Suica (for tourists) has no deposit fee. You can also set up a mobile Suica on your iPhone or Android through the Suica app.
