Everyone knows that big data is important. As everyone has experienced, for example, if you search for hiking boots on your phone, advertisements for hiking boots and hiking items appear on Facebook. Coupang, Naver Shopping, and Kakao Pay all know what I bought online. Facebook knows who my friend is and what I like. Through cookie information, I know what sites I visited.

Now, Line and Yahoo Japan merged in October last year. Line has 96 million users in Japan, nearly 100 million, and Japan has 100 million monthly Internet users, 80 million of whom are Yahoo Japan users.

In addition, it was possible to shop through Line, and Yahoo Japan was able to shop online through a payment system called PayPay. Line Pay (39.7%) tops the Japanese smartphone online payment list, followed by PayPay (38.9%).

Line’s global share in the picture below is a little old because it is data from 2016, but according to Lineyahu’s website, Lineyahu has an overwhelming share of 194 million monthly users in Japan, Taiwan (90%), and Thailand (90%). This means Lineyahu has vast amounts of big data in Japan, Taiwan, and Thailand.

Now, it means that Naver loses it. I think Naver may have made a mistake in its management or judgment, or maybe it was because of some OO.
