PayPay

• Reading: ペイペイ
• Romaji: pei pei
• Pronunciation: /pe.i.pe.i/

Meaning

Japan's dominant mobile payment app, owned by SoftBank/Z Holdings, used for QR code payments.

PayPay launched in 2018 and quickly became Japan's most-used mobile payment through massive marketing and 20% cashback campaigns. The name itself has become almost synonymous with mobile payment in Japan, similar to how 'Venmo' is used in the US. The characteristic 'ペイペイ♪' sound at checkout is instantly recognizable. It's used colloquially as a verb too — 'PayPayで送って' (send me via PayPay).

Examples

1. ここPayPay使える？財布忘れちゃって。 Can I use PayPay here? I forgot my wallet.
2. ワリカンめんどいからPayPayで送ってくれない？ Splitting the bill is a hassle — can you just send it to me on PayPay?
3. PayPayのポイント還元キャンペーンがあるから今のうちにまとめ買いする。 There's a PayPay cashback campaign right now, so I'm gonna stock up.
