Growing LINE
On LINE, people follow a business by adding its Official Account as a friend. Your plan sets how many messages you can send them each month.
Basics
How many people use LINE?
100 million people a month in Japan, by LY Corporation's count at the end of March 2026. Across LINE's four biggest countries, LY counts 181 million monthly active users.[1, 2]
How do you grow a LINE Official Account?
Get people to add you as a friend, then send messages worth opening.

| Add a button to your site | Copy the "Add friend" button's HTML tag |
| Set a rich menu | A menu friends can open from the chat at any time |
| Send coupons | Coupons are one of the message types you can send |
| Run ads that add friends | LINE Yahoo ads can charge per friend added |
Advanced
Can you advertise on LINE?
Yes, in Japan, through LINE Yahoo ads, which show in LINE's chat list and on Yahoo! JAPAN. There's no minimum spend, and LY says you can start from a few thousand yen a day.
You pay per click, view, video play or friend added. LINE Ads and Yahoo! Ads merged on 1 April 2026.[2]
Which LINE Official Account plan do you need?
The free Communication plan suits a small friend list; paid plans include more messages each month.
| Plan | Japan, per month | Messages included |
|---|---|---|
| Communication | Free | 200 |
| Light | ¥5,000 | 5,000 |
| Standard | ¥15,000 | 30,000, then about ¥3 each |
Japanese prices exclude tax. LY's English page lists the free plan with 500 messages, Light at $50 with 10,000 and Standard at $150 with 40,000. Replies to a friend's message don't count.[5, 6, 7]
What can you do with LINE's Messaging API?
Run a bot or app that replies to friends, messages them at any time and sets rich menus.
| Feature | Detail |
|---|---|
| Replies | Don't count toward your monthly messages |
| Push, broadcast, narrowcast | Count once for each person reached |
| Rich menus | Set and customize them |
| Account linking | Link your own service's accounts to LINE |
Getting started is free: create an Official Account, then a Messaging API channel.[4, 5]
