At the same time, Son also stated that he wants his portfolio unicorns to synergise, which partly explains why his Indian unicorns are going all over the world. “We will see synergies between portfolio companies, which support and cooperate with each other, so that we can design new strategies with them,” said Son. No wonder, then, that Didi Chuxing was even rumoured to be investing in Oyo’s China operations. In July 2018, SoftBank, launched a mobile payment app PayPay in collaboration with Yahoo Japan. Son intends to utilise Paytm’s QR code expertise here, which it perfected in India. It offers ease of payment, which could change Japanese customer’s behaviour. The Japanese market is as cash-loving as India — credit cards, electronic money and other cashless systems account for only 29% of all consumer payments. In contrast, in China, the rate of cashless payments is 60% and in South Korea, 90%. Hiroyuki Miyamoto, partner at Nomura Research Institute, indicated in his report that there is a change in payment behaviour anyway: “The percentage of people who used electronic money at least once in the previous six months has been rising rapidly, up from 11% in 2010, to 18%in 2013 and 29% in 2016.” To grab a large chunk of the growing digital payment market in Japan, SoftBank-Paytm combine will be competing with Amazon, Rakuten (Japan’s version of Amazon), NTT DoCoMo (Japan’s largest telecom carrier) and Line (Japan’s version of WhatsApp).
