Paytm, India’s biggest mobile payments firm, now has 10 million customers in Japan, the company said as it pushes to expand its reach in international markets. Paytm entered Japan last October after forming a joint venture with SoftBank and Yahoo Japan called PayPay.

In addition to 10 million users, PayPay is now supported by 1 million merchant partners and local stores in Japan, Vijay Shekhar Sharma, founder and CEO of Paytm said Thursday. The mobile payments app has clocked more than 100 million transactions to date in the nation, he claimed. In June, PayPay had 8 million users.

“Thank you India 🇮🇳 for your inspiration and giving us chance to build world class tech…,” he posted in a tweet.

Like in India, cash also dominates much of the daily transactions in Japan. Large medical clinics and supermarkets often refuse to accept plastic cards and instead ask for cash. This encouraged Paytm, which also has presence in Canada, to explore the Japanese market.

And it has the experience, capital and tech chops to achieve it. The mobile payments app has amassed more than 250 million registered users in India. Most of these customers signed up after the Indian government invalidated much of the cash in the nation in late 2016.

PayPay competes with a handful of local players in Japan. Its biggest competition is Line, an instant messaging app that has followed China’s WeChat model to aggressively expand its offerings in recent years.

Like PayPay, Line also has no shortage of money. Earlier this year, it announced a ¥30 billion ($282 million) reward campaign to boost usage of its payments service. Line has more than 80 million users in Japan, 32 million of whom used its payments service as of February this year. There are about 120 million internet users in Japan.

PayPay maintains a ¥10 billion ($94 million) marketing campaign of its own, as part of which customers who make a certain number of transactions and participate in referral programs earn some money. In a statement, PayPay said Thursday that moving forward it “will strive to create a society where people can buy anything through cashless payments in every corner of the country with a safe and secured service for our users.”
