Line became Japan's largest social network in 2013, with more than 300 million users. It reached 100 million users within 18 months and 200 million users six months later. Because it was tailored to Japanese consumers' tastes and offered free smartphone calls as well as texting, with the help of a massive marketing campaign it quickly outpaced its existing rival KakaoTalk for the Japanese market. Line was launched in Japan in June 2011 by NHN Japan, a subsidiary of Naver Corporation. The service is operated by Line Corporation, a Tokyo-based subsidiary of Z Holdings.
