Line is a major Japanese freeware application used for instant messaging and social networking. It is operated by LY Corporation, a company co-owned by SoftBank Group and Naver. While it began as a simple tool for texting, it has evolved into what is known as a "super-app." This means the platform provides many different services within a single interface. Users can access digital wallets, news streams, video on demand, and digital comics. Today, Line is a central part of digital life for millions of people.

The core mechanism of Line involves sending data over internet networks. The app was designed to work on smartphones, tablets, and personal computers. It utilizes data networks, such as 3G or Wi-Fi, to transmit various types of information. This includes text messages, photos, music, and voice recordings. Users can also engage in VoIP, which stands for Voice over Internet Protocol. This technology allows for free voice and video calling over the internet. The app even supports group chats that can hold up to 500 members.

Line offers several distinct features that set it apart from standard messaging tools. One major feature is the Sticker Shop, where users buy virtual stickers. These stickers act as large, expressive emojis to help convey emotions during chats. Another important feature is the "Timeline," which functions similarly to social media status updates. Users can share personal developments with their contacts in real-time. The app also includes "official channels." These allow news media outlets and large companies to send regular updates directly to users.

The history of Line is rooted in a significant natural disaster. In March 2011, the Tōhoku earthquake and tsunami struck Japan. This event left millions of people without electricity or traditional phone lines. NHN Japan co-founder Lee Hae-Jin and his engineers were in Japan during this time. They noticed that while phone lines were down, Wi-Fi and some 3G networks remained usable. This inspired the team to develop an app that used data networks for continuous messaging. They launched Line in June 2011 to provide a reliable way to communicate.

Line experienced rapid growth following its launch. It reached 100 million users within only 18 months. By the end of 2013, it became Japan's largest social network. At that time, it had more than 300 million registrants worldwide. By 2014, the company announced it had attracted 560 million users. The user base continued to climb, reaching 700 million by 2017. As of 2023, more than 70% of the Japanese population uses the service. In 2025, the platform reached approximately 194 million monthly active users.

Beyond messaging, Line has expanded into diverse industries like finance and gaming. Line Pay is a digital wallet service that allows for mobile payments in stores. It even supports offline wire transfers and ATM transactions. The company also developed Line Games, which includes titles like Line Rangers and Line Tsum Tsum. These games allow players to connect with friends to earn points. In 2015, the company even entered the transportation sector with Line Taxi in Tokyo. This service allowed users to request a taxi and pay automatically via Line Pay.

Line's influence extends across many different technological and social systems. It has moved from being a mobile-only app to a multi-platform service. It is available on Android, iOS, Windows, and macOS. The app's success changed how people in Japan communicate. It eventually replaced carrier-based email as the most popular communication method. Even senior citizens in Japan have begun to prefer Line over traditional email. This shows how a single application can reshape the communication habits of an entire nation.
