LINE OpenChat Live talk: how many members you need to start one, and its limits
SocialContactApp · Fu Xin Co., Ltd. · Updated 2026-10-28
To start a Live talk in LINE OpenChat, the chat room needs at least 10 members, and only the admin and co-admins can start it; regular members don't see the option. Each chat room, sub-chat rooms included, counts its own members. LINE's announcements in Japan show how the requirement changed: 50 members at launch in July 2023, 30 from September 1, 2023, and 10 since March 20, 2024. Note that OpenChat is only available in Japan, Taiwan and Thailand.
How many members to start a Live talk: 10 or more per chat room
LINE's OpenChat sites for Japan and Taiwan say a Live talk can be started in any chat room with at least 10 members. The count is per chat room, so a sub-chat room needs 10 members of its own. The Japanese site says the rule is there for safety reasons. The LINE Help Center page on Live talk does not mention a minimum, so if the app in your region behaves differently, the app wins.
- Members needed: 10 or more in that chat room.
- Who can start: the OpenChat admin and co-admins only; regular members don't see the option.
- Who can join: members of the OpenChat; if the Live talk allows non-members, they can join as listeners.

Why some pages say 50 or 30 members
The number of members needed to start a Live talk has been lowered twice. LINE's announcements in Japan:
| When | Members needed | Announced in |
|---|---|---|
| June 2023 (Japan, test notice) | 50+ | LINE OpenChat Japan notice |
| July 12, 2023 (Japan launch) | 50+ | LINE Corporation press release |
| September 1, 2023 | 30+ | Update to the same press release |
| March 20, 2024 onward | 10+ | LINE OpenChat Japan site |
That is why articles from 2023 say 50 or 30. LINE's OpenChat site for Taiwan also says 10 or more today. The press release notes that the conditions may change without notice, so the LINE app has the final word.
Who can start a Live talk, and who can join
- Admin and co-admins: only they can start a Live talk. The OpenChat admin and the Live talk's host and co-hosts can end it.
- Host and co-hosts: run the Live talk. Up to 99 co-hosts can be chosen, from OpenChat members only.
- Speakers: can talk; up to 100 including the host.
- Listeners: can only listen.
A Live talk can be limited to members or opened to non-members. Non-members can only join as listeners; to speak or react, they have to join the OpenChat. Hosts and co-hosts can remove all non-member listeners at once during a Live talk.
Live talk limits
| Item | Limit |
|---|---|

| Speakers | Up to 100, including the host and co-hosts |

How to start a Live talk
- Open the OpenChat and tap “+” to the left of the message box.
- Choose Live talk.
- Set the topic, whether non-members can join, and the speakers.
- Tap start.
Menu names can differ by app version and country. While a Live talk is running, its details may appear in the Live talk area of the OpenChat home screen, in category areas and on the OpenChat's cover page, but not for OpenChats that require approval to join or don't allow search. When you end a Live talk, LINE's Japanese guide warns not to confuse “end” with “leave” on the confirmation screen.
Can't see or start a Live talk? Check these
- Fewer than 10 members in the chat room: a sub-chat room counts its own members.
- You're not the admin or a co-admin: regular members don't see the option.
- A Live talk is already running in that chat room: the Japan launch announcement allows one per chat room.
- Your LINE app is out of date: update it and check again.
- Other OpenChats' Live talks don't show up: OpenChats that require approval to join or don't allow search don't show Live talk details on the home screen.
- You're outside Japan, Taiwan or Thailand: according to the LINE Help Center, OpenChat is only available there.
Recording, music and monitoring
- Don't record and share it: according to the LINE Help Center, recording a Live talk and sharing it to OpenChat or other platforms is prohibited in principle under LY Corporation's common terms of use; so is streaming the same Live talk from several devices or mirroring it to other platforms.
- Don't play CD tracks or karaoke backing tracks: the Q&A on LINE's OpenChat site for Japan (updated May 30, 2025) says doing so may infringe copyright.
- Live talks are monitored: according to the LINE Help Center, LINE monitors Live talks.
- Tell listeners before removing non-members: hosts and co-hosts can remove all non-member listeners at once; LINE's Japanese guide asks hosts to explain this as a speaker before doing it.
