LINE is a messaging and communications app best known for fast chat, voice/video calls, and an outsized presence in Japan and parts of Southeast Asia. Over time it has expanded into a “super-app” style ecosystem that includes news, digital content, stickers, games, and (historically) payments and fintech features. Today, LINE’s scale is still anchored in everyday communication—especially in Japan—while monetization leans on ads, stickers, and content services.
Answer box: LINE has 194 million global monthly active users (MAU) as of March 31, 2025. In Japan alone, LINE has 98 million MAU (late March 2025).

Note on country metrics: LY Corporation’s international MAU figures (Taiwan/Thailand/Indonesia) are defined in its appendix as the number of LINE users on iOS and Android devices (excluding some other authenticated devices). That definition can differ from older “four key markets” reporting from LINE’s public-company era.
What Is LINE Used For?
LINE started as a messaging app, but in its core markets it functions more like a daily communications layer for modern life: quick chats, group coordination, brand/customer messaging, and content discovery. LINE is also famous for its character-driven stickers and a creator marketplace that helps keep users engaged.
- Messaging and group chat: everyday communication for friends, families, and communities.
- Voice and video calls: free calling features inside the app.
- Content and discovery: news and media experiences in supported regions.
- Stickers and characters: a major cultural and monetization driver.
- Brand and business messaging: official accounts and marketing placements in key markets.
