About PayPay India
PayPay, a fintech company providing a service enjoyed by over 70 million users (as of July 2025) merely 7 years since its launch in 2018 in Japan.

Why India ?
To build our Payment services, we got technical cooperation from Paytm (A large payment service company in India).

Therefore, we have decided to establish a development base in India, because it is a major IT country with many talented engineers, as evidenced by the fact that cutting-edge mobile payments can continue to be generated.
OUR VISION IS UNLIMITED
We dare to believe that we do not need a clear vision to create a future beyond our imagination. PayPay will always stay true to our roots and realise a vision (future) that no one else can imagine by constantly taking risks and challenging ourselves.
