Overseas brands welcome. We work in English, Japanese, Chinese, and Korean.TL;DR: LINE reaches 100 million monthly active users in Japan, which is more than any other platform in the country. Only companies registered in Japan, Taiwan or Thailand can apply for a verified account, so most overseas brands start unverified. LINE VOOM, the only in-app feed where creators could be discovered, closes on 30 September 2026, which means LINE works as a CRM channel rather than an awareness channel.
Most overseas brands arrive in Japan with a channel plan built around Instagram, TikTok and paid search, then hear the same sentence from every local partner: you also need LINE. The advice is correct, but it is rarely explained. LINE is not a Japanese equivalent of WhatsApp, and it is not a social network you can bolt onto an existing content calendar. It is the messaging layer that Japanese consumers use to talk to their friends, their doctor, their local government office and the brands they buy from.
This guide answers the three questions that actually decide whether LINE belongs in your Japan plan: what a LINE Official Account costs in yen, what you can and cannot do on the platform as a foreign company, and who ends up running it day to day. Where the rules change on a specific date, the date is stated, because two of them fall inside the next twelve months.

LINE Is Not a Social Network. It Is Where Japan’s Customer Relationships Live
LINE had 100 million monthly active users in Japan as of the end of December 2025, according to LY Corporation, the company that operates the service. That figure is worth pinning to its date, because most English-language articles quote a range of 90 to 100 million without saying when it was measured.
Scale alone is not the interesting part. Reach across age groups is. Japan’s Ministry of Internal Affairs and Communications puts LINE usage at 91.1% in its FY2024 survey of people aged 13 to 79, with every bracket from teenagers to people in their sixties above 90%, and 71.8% among people in their seventies. No other platform in Japan comes close to that spread, and very few platforms anywhere do.
Instagram is absent because Meta publishes no current Japanese figure. The gap between first and second place is not a normal ranking gap — it is the difference between a large platform and national infrastructure.
Sources: LY Corporation (LINE), Google Japan (YouTube, adults only), X Japan, ByteDance Japan, Meta. Figures are not measured on a common basis; each date is shown.
Read the right-hand column carefully. Several of these platforms stopped publishing Japanese user numbers years ago, which is why the same stale figures circulate in market entry decks. LINE is the exception: LY Corporation reports it regularly, and it is the number your Japanese colleagues will quote back to you.
The practical consequence is that LINE is not competing with Instagram for a slot in your content calendar. It sits underneath the whole funnel as the place where a customer relationship continues after the first purchase. For the full ranking of Japanese platforms and what each one is used for, see our overview of social media in Japan.
What a LINE Official Account Actually Costs
A LINE Official Account is free to open. What you pay for is volume: every message you broadcast to your followers is metered, and the plan you choose sets how many messages are included before per-message billing starts.
Communication
Free
200 messages a month. No additional messages can be bought at any price — when you run out, you stop sending.
Light
¥5,000 /mo
5,000 messages a month, and again no overage. A 2,000-follower list sending three broadcasts hits the ceiling.
Standard
¥15,000 /mo
30,000 messages a month plus the ability to buy more. The only plan on which a growing list does not hit a wall.
Additional messages on Standard, priced per message (rates through September 2026):
Cost scales with followers × sends, not with the plan fee. A 20,000-follower list broadcasting four times a month sends 80,000 messages: the ¥15,000 fee is the small number in that calculation.
All figures exclude tax. Every message to every recipient counts individually, which is why segmentation is a cost control rather than a nicety. The volume bands change on 1 October 2026 to two tiers: ¥3.0 up to 200,000 additional messages, ¥2.5 above that — see below before you build a budget on these numbers.
Note which plans allow overage at all: only the Standard plan permits additional messages beyond its allowance. On the Communication and Light plans, sending stops at the included number and you have to upgrade. Two further details catch overseas teams out. First, a message is counted per recipient, not per send: a single broadcast to 10,000 followers consumes 10,000 messages. Second, one send can contain up to three bubbles and still counts as one message, while auto-replies and responses inside a one-to-one chat are not counted at all. A brand doing weekly broadcasts to 30,000 followers is not on the Standard plan, it is well past it.
Per-message pricing on the Standard plan is tiered, and the rates shown above hold through September 2026.
LY Corporation quotes volumes above 10 million messages individually. Its own worked example puts 200,000 additional messages at 550,000 yen.
This changes on 1 October 2026. LY Corporation is replacing the three-band structure with two: 3.0 yen per message up to 200,000 additional messages, and 2.5 yen for everything above that. If you send at low volume, your cost per message stays where it is. If you send in the hundreds of thousands, your marginal rate improves. The awkward middle is the brand sending between 50,000 and 200,000 additional messages a month, which currently benefits from the 2.8 and 2.6 yen bands and will move back to 3.0 yen. Any Japan budget built before this date should be re-run against the new bands.
Budget the operating cost as well as the platform cost. Someone has to write in Japanese, segment the audience, design rich menus and answer the replies that come back, and that work is where LINE budgets actually go. Our breakdown of influencer marketing costs in Japan covers the equivalent numbers on the creator side, which is usually the other half of the same plan.
Not sure which plan your send volume lands on? The answer depends on how fast you expect to grow your follower base, not on your current list size. Ask us for a free estimate and we will model the message volume and running cost against your launch plan.
How Brands Use LINE for Business
LINE for business is not one product. It is an account you own, an ad network you buy, and a set of commerce features you can plug into, and the three are billed and managed separately. Most brands start with the account and add the rest once they have followers worth talking to.
Official Accounts: Broadcast, Segments and Rich Menus
The Official Account is the asset. Users add you as a friend, and from that point you can reach them in the same inbox where their family messages sit. That access is valuable and easy to abuse, which is why the three core tools exist to keep frequency down.
- Broadcast. One message to your entire follower base. Simple, expensive at scale, and the fastest way to trigger blocks if you overuse it.
- Segmented delivery. Filtering by attributes such as age band, gender, area and operating system, or by tags you have applied yourself through the Messaging API. Sending to a quarter of your list costs a quarter as much and usually performs better.
- Rich menus. The permanent tiled panel at the bottom of the chat window. It is the closest thing LINE has to a homepage: store locator, reorder, loyalty card, support. Because it costs nothing per view, a well-built rich menu quietly absorbs traffic that would otherwise require a broadcast.
Blocking is the metric to watch. Japanese users block business accounts freely and without warning, and a blocked follower keeps counting toward nothing. Treating the channel as a monthly newsletter is the most common way to lose a list you spent real money building.
LINE Ads: Where Your Ads Appear
LINE Ads is the paid side, and LY Corporation puts its reach at 100 million monthly users as of the end of March 2026. The inventory that has no equivalent outside Japan is the chat list itself: a small ad unit that appears at the top of the screen where users see their conversations. Attention there is extremely high, and so is the sensitivity to anything that feels intrusive.
Beyond the chat list, placements run across LINE NEWS, the mini-app tab, coupon and points surfaces, LINE family apps such as LINE Manga, and a third-party app network. For most entrants the highest-return use of LINE Ads is not direct response at all. It is adding friends: campaigns that pay to grow the Official Account. Note the dependency before you budget for it, because LINE’s friend-add product is available only to verified accounts, which brings you back to where your company is registered. Growing the account this way, which then costs a fraction as much to reach again.
Sponsored Stickers: What They Are For
Sponsored stickers are branded sticker sets that users download for free and then send to each other in private conversations. They are a mass awareness buy with a long tail, priced accordingly, and they are usually the wrong first purchase for a brand nobody in Japan has heard of yet. Know that the menu exists, and revisit it when you have a name worth putting inside someone’s chat with their friends.
LINE Mini App and LINE Gift
Two commerce features are worth knowing before you scope a Japanese ecommerce build.
LINE Mini App lets you run a web app inside LINE with no install and no separate login, using the user’s existing LINE identity. Reservations, membership cards, order status and queue tickets are the common cases. For a brand whose Japanese customers would never download a standalone app, this is often the realistic version of “our app”.
LINE Gift handles social gifting: you send a present to someone through the chat, and the recipient supplies their own delivery address. Gifting is a large and habitual part of Japanese consumer culture, so for gift-suited categories such as beauty, confectionery and small lifestyle goods, this is a distribution channel and not a novelty.
Can You Do Influencer Marketing on LINE? A Straight Answer
No, and after 30 September 2026 the answer is no without qualification. We say this as an influencer marketing agency, so it is worth being precise about why, because the conclusion changes how you should plan the channel.
LINE VOOM Shuts Down on 30 September 2026
LINE VOOM was the in-app feed of short videos and posts, the one place inside LINE where a creator could publish to strangers and be discovered. In the app renewal of 16 September 2025 it lost its slot in the bottom navigation bar. In July 2026 LY Corporation announced that the service will end entirely on 30 September 2026, and the VOOM Creator Program, which paid creators for views, ends on the same day.

Tell us your category, budget range, and timing. We will take it from there.When it goes, LINE has no public feed, no discovery surface and no ad-funded creator programme. Every English-language guide still describing VOOM as a way to reach Japanese audiences is describing something that is being switched off. If a proposal you have received includes LINE VOOM activity, that is a useful signal about how current the rest of it is.
The Two Setups That Do Work
Creators still play a part in a LINE strategy. They just do not operate inside LINE.
- Acquire elsewhere, nurture on LINE. Creators build awareness on TikTok, Instagram or YouTube, and the call to action sends viewers to add your Official Account, usually with a first-purchase coupon. From there the conversation, the reminders and the repeat purchase happen on LINE at a fraction of the cost of buying that attention again.
- The creator’s own account does the sending. Established Japanese talent often run their own Official Accounts for their fan base, and some tie-ups include a broadcast to that list. You are buying access to a curated audience, which is a media buy, and it needs the same disclosure treatment as any other paid post under Japan’s stealth marketing regulation.
The short version: LINE is not where you get discovered in Japan. It is where the relationship lives once you have been.
The Rule That Blocks Most Foreign Brands: Account Verification
This is the part that decides your timeline, and it is missing from almost every English article on the subject. LINE Official Accounts come in two states: unverified and verified. A third, premium tier existed until April 2026, when LY Corporation folded every reviewed account into a single verified status marked by a green checkmark, so guides that still describe three tiers are out of date. The verified badge is not a vanity marker. It is the gate to search visibility and to part of the ad system, and eligibility for it is decided by where your company is registered.
Only Japan, Taiwan and Thailand Can Apply
Applications for a verified account are accepted only from businesses based in Japan, Taiwan or Thailand, and LY Corporation states that a review takes five to ten business days. A company registered anywhere else cannot submit one, no matter how large the brand or how much it spends on LINE Ads. There is no international application route, and no fee that changes the answer.
In practice this means your Japanese entity, distributor or agency partner is the applicant. Which of those three it is has consequences you should settle early, because whoever applies is the party the account belongs to.
What You Lose Without the Verified Badge
An unverified account is not a broken account. You can open it in a few minutes from overseas, broadcast, use rich menus and run the Messaging API. The one hard geographic limit is that LINE states the Official Account service is not available in the European Union, so an EU-registered entity cannot open one at all. The restrictions are narrower than people assume, and they are all on the discovery and payment side.
Unverified account
- Open the account and broadcast
- Rich menus, segments, Messaging API
- Appear in LINE’s in-app search
- Verified badge shown to users
- Ad products and invoice payment — limited
Verified account
- Open the account and broadcast
- Rich menus, segments, Messaging API
- Appear in LINE’s in-app search
- Verified badge shown to users
- Full access to ad products and invoice payment
The functional account works either way. What you lose is discovery and the visual signal of legitimacy — in a market where trust precedes purchase, the badge is doing more work than the feature list suggests.
Only entities based in Japan, Taiwan or Thailand can apply for verification. For most overseas brands this makes a Japanese entity or a local partner a prerequisite, not an optimisation.
The one that hurts is search. Without verification, users cannot find you by typing your brand name into LINE. Every follower has to arrive through a QR code, a link on your site, an ad or a creator post, which turns friend acquisition into a paid problem rather than an organic one. The badge also carries the ordinary trust signal, which matters in a market where consumers are cautious about giving a business access to their message list.
What This Means for Your Entry Plan
Sequence the work in this order. Open an unverified account now if you want to test creative and message flow, because nothing is lost by starting. Treat verification as a milestone that depends on your Japanese legal footing, and put it on the same track as entity setup, not on the marketing track. If your entry model does not include a Japanese entity at all, decide deliberately whether your distributor or your agency holds the account, and write the handover terms into the contract before the follower base becomes valuable.
The choice of entry structure drives all of this, along with a good deal else. Our guide to Japan market entry and marketing strategy walks through the structures available and what each one lets you do locally.
Verification is a structural question, not a form. If you do not yet have a Japanese entity, the practical route runs through a local partner who can apply for and operate the account in Japanese. Talk to hotice about your setup and we will map out what your current structure allows.
How LINE Fits With the Rest of Your Japan Channel Mix
LINE is a retention channel. Putting it anywhere else in the funnel produces the disappointing results that make brands conclude it does not work for them.
LINE is bad at exactly one thing: being found by someone who does not already know you. Everything above the last row has to come from elsewhere. The mistake is not choosing LINE too late — it is expecting it to create demand, then concluding it does not work.
The corollary: acquiring a Japanese customer and then having no way to reach them again is the most expensive mistake in the plan, and LINE is the channel that fixes it.
| Channel | Funnel role | What it is good at | What it is bad at |
|---|---|---|---|
| TikTok / Instagram / YouTube | Awareness | Reaching people who have never heard of you, through creators | Repeat contact with a known customer at low cost |
| Search and owned site | Consideration | Answering the questions people ask after they notice you | Creating the demand in the first place |
| X | Consideration and conversation | Real-time reaction, campaign amplification, a genuinely large Japanese base | Structured one-to-one follow-up |
| LINE | Conversion and retention | Reaching a known customer directly, repeat purchase, support, coupons | Being found by anyone who does not already know you |
| Retention | Long-form, B2B, transactional records | Open rates in a consumer market that lives in LINE |
Two planning rules follow from the table. Do not launch LINE before you have anything driving traffic to it, because an Official Account with 200 followers is a cost with no return. And do not let the Japanese team run LINE in isolation from the creator campaigns, because the coupon in the creator’s caption and the welcome message in LINE need to be the same offer.
A Realistic First 90 Days on LINE
The plan below assumes you already have some traffic in Japan, whether from creator campaigns, paid media or an existing distributor. If you do not, spend the first quarter on awareness and start this in month four.
-
Days 1 to 30 · set upA live account a Japanese speaker would take seriously
Open the account, decide who holds it, start the verification track if you are eligible, write the greeting message and build a first rich menu in Japanese. End the month with the ownership question answered, not deferred.
-
Days 31 to 60 · acquireA follower base large enough that segmentation means something
Put the QR code and add-friend link into every touchpoint you control, run friend-add ads if your account is verified, and give creators a reason to send people to LINE — usually a first-purchase coupon. You should know your cost per friend by the end of it.
-
Days 61 to 90 · send and measureA frequency your audience tolerates and a cost you can forecast
Move from broadcast to segmented delivery, set a sustainable frequency, watch the block rate after every send, and check message volume against your plan tier before the bill tells you.
Block rate is the metric to watch. In Japan an over-frequent LINE account is not ignored the way an email is — it is blocked, and that follower does not come back.
Track three numbers from the first week: friends added, block rate, and messages consumed against your plan allowance. The first tells you whether acquisition is working, the second tells you whether your content is welcome, and the third tells you what next month’s invoice will look like.
LINE Marketing FAQ
Can foreign companies create a LINE Official Account?
Almost anywhere. LINE states that the Official Account service is not available in the European Union, but from anywhere else you can open an account and broadcast, build rich menus and use the Messaging API from overseas. What is restricted is verification, which is a separate application.
Do you need a Japanese company to get a verified LINE account?
You need a business registered in Japan, Taiwan or Thailand to apply. For most overseas brands that means a Japanese entity, or a distributor or agency partner applying on the brand’s behalf. Agree in writing who owns the account before you start building the follower base.
How much does a LINE Official Account cost per month?
The Communication plan is free with 200 messages a month. Light is 5,000 yen excluding tax with 5,000 messages, and Standard is 15,000 yen excluding tax with 30,000 messages. Only the Standard plan allows additional messages beyond the allowance, billed from 3 yen each excluding tax, and messages are counted per recipient. Confirm the current figures on the official LY Corporation pricing page before you commit a budget.
Is LINE bigger than WhatsApp in Japan?
Yes, and the gap is not close. LINE is the default messenger in Japan with 100 million monthly active users as of December 2025, while WhatsApp has never had meaningful adoption there. If your global CRM stack assumes WhatsApp, Japan is the market where that assumption fails.
Can you do influencer marketing on LINE?
Not inside the platform. LINE VOOM, the only feed where creators could be discovered, closes on 30 September 2026, and LINE has no other public discovery surface. Creators can still drive people to your Official Account from TikTok, Instagram or YouTube, and established talent sometimes broadcast to their own LINE followers as a paid tie-up.
What is happening to LINE VOOM?
LY Corporation announced in July 2026 that LINE VOOM ends on 30 September 2026, together with the VOOM Creator Program. It had already been removed from the bottom navigation bar in the app renewal of 16 September 2025. Any plan built around VOOM needs to be rewritten.
Is a LINE Official Account the same as LINE Ads?
No. The Official Account is the owned channel you use to message people who have added you. LINE Ads is paid placement across the chat list, LINE NEWS and other LINE surfaces, with a stated reach of 100 million monthly users as of March 2026. Most brands use ads to grow the Official Account, then use the account to sell, though the friend-add ad product itself requires a verified account.
Where to Go From Here
If you take three things from this article, take these. LINE reaches more people in Japan than any other platform, and it reaches them at ages other platforms do not. It is a retention channel, not a discovery one, and after September 2026 there is no argument left about that. And the verified badge, which decides whether people can find you by name, depends on having a business registered in Japan, Taiwan or Thailand.
That last point is where most entry plans stall, and it is not really a LINE problem. It is a question of who represents you in Japan, in Japanese, on an ongoing basis.
