LINE Marketing for Business: Official Accounts, Ads, and Use Cases

If you are planning a Japan launch, LINE is not optional. Nearly everyone in the country uses it daily to talk to friends, family, and — increasingly — the businesses they buy from, making it one of the few places a brand can hold a direct, opted-in relationship with a Japanese customer.

The single most important thing to understand about LINE marketing is that it splits into two very different jobs: a LINE Official Account is your owned channel for keeping and re-engaging customers, and LINE Ads is a paid channel for finding new ones. You need the account to do anything durable, and you usually need a paid or offline source to fill it. This guide walks through both, the pricing model that quietly shapes every program, and the access rules that decide what an overseas company can actually do.

One disclosure up front: LOads is a bilingual Japan marketing agency, and we run LINE programs for clients, so we have a commercial interest here. We have written this guide openly so you can weigh our perspective rather than have it sprung on you at the end.

Why LINE matters so much in Japan

LINE is a messaging app — think WhatsApp or Messenger — but in Japan its reach is closer to a utility than a social network. According to DataReportal’s Digital 2026: Japan report, whose data references late 2025, LINE has 99.0 million monthly active users in Japan — 80.5% of the population and 92.6% of the country’s internet users, ahead of YouTube (78.5M), X (71.2M), and Instagram (63.2M). It has sat at the top for years.

Two things follow. LINE is not a niche you can safely skip — it is where your Japanese customers already are. And because people use it for private conversation, a message from your brand lands in the same inbox as a user’s family chats: high-trust and high-attention, but unforgiving of a badly targeted broadcast in a way a skippable feed ad never is.

A note on the corporate name, since you will see both: the operator historically called LINE Corporation is now LY Corporation — formed after the LINE and Yahoo! JAPAN merger, with the business brand “LY for Business.” Older guides still say “LINE Corporation”; the product is the same, the entity name changed.

What “LINE marketing” actually means

LINE marketing is the practice of reaching and retaining customers through the LINE app — primarily by running a LINE Official Account (your owned audience) and, separately, by buying LINE Ads (paid reach). A short glossary keeps the pieces straight, since most of these terms have no clean Western equivalent.

• LINE Official Account (LINE公式アカウント) — a business profile that lets a brand message users who have opted in. The core of LINE marketing.
• Friends, or tomodachi (友だち) — users who “add” your Official Account. Tomodachi is the Japanese word for “friends”; here it means your opted-in subscribers, like an email list you own.
• Rich menu — a persistent, tappable image menu pinned to the bottom of the chat. Per LINE’s developer documentation, it is divided into tappable areas that open URLs or trigger actions — store, coupons, reservations, one tap away.
• Broadcast message (一斉配信) — a message sent to all your friends, or a segment, at once.
• Step message (ステップ配信) — an automated, triggered sequence, such as a welcome flow after someone adds you.
• LINE Ads — LINE’s paid advertising platform, placing ads in the chat list, LINE VOOM (its video feed), and partner apps.
• LINE Pay — LINE’s mobile wallet, part of why LINE behaves as consumer infrastructure and not just chat.

The Official Account: your owned channel

The Official Account is where the durable value sits. Once a user adds you as a friend, you reach them directly — no algorithm deciding whether your post appears, as on Instagram or X. That is the same structural advantage email has over organic social, and why we treat the Official Account, not Ads, as the foundation of any LINE program.

Can you stand one up yourself? Broadly, yes — this is the DIY-friendly half of LINE. You create an Official Account through a LINE Business ID (LINE’s business login) on the free Communication plan and build a basic rich menu without a Japanese entity; a non-Japanese team, with support, can operate the admin backend and run simple broadcasts. Three things pull in local help: verification (below), LINE Ads billing (later), and — above all — native-Japanese consumer copy. The messages customers read cannot be machine-translated; LINE’s inbox sits next to a user’s family chats, so auto-translated Japanese reads as intrusive and erodes the trust that makes the channel valuable. That copy requirement is what most often moves a brand from DIY to a local operator.

What you can do with it: broadcasts for announcements and offers to your whole friend base or a segment; step messages to automate onboarding and follow-up; a rich menu that turns the chat into a mini app (store, coupon, and booking buttons always visible); coupons and promotion stickers to drive adds and repeat visits — the reason so many Japanese retailers ask you to add their account at the register; and one-to-one chat for support and sales.

Verified, premium, and unverified

Official Accounts carry a badge: an unverified account shows grey and cannot be found in LINE’s in-app search; a verified account shows blue after LINE reviews your business; a premium account shows green, the highest tier. Verification gates in-app discoverability and signals legitimacy to cautious Japanese consumers, so it is worth pursuing. One caveat tied to the access section below: LINE’s verification review assumes Japanese-language operation and a local contact, so it is realistically easier once you have a Japanese operator or partner. Stepping in solo, run an unverified account first and pursue verification when a local contact exists — you need not solve everything on day one.

How message-count pricing shapes everything

Here is the mechanic that catches most newcomers. LINE Official Account plans are priced by the number of messages you send, not by the size of your list. A free tier covers a monthly quota; once you exceed it you pay per message. For a directional sense of scale — verify before you budget — as of early 2026 the free Communication plan covers on the order of a few hundred messages a month, with paid tiers (LINE’s Light and Standard) starting around a few thousand yen a month for a larger quota. Because tiers and currencies differ by region and change over time, confirm the figures at LINE’s own Messaging API pricing documentation rather than trusting a blog.

The design implication matters more than any specific price. On email, sending to more people costs roughly nothing, so teams blast frequently. On LINE, every message to every friend draws down a quota, so cost is controlled by segmentation and relevance, not frequency for its own sake — a well-run program sends fewer, better-targeted messages to the segments most likely to act. This is also why LINE is not a top-of-funnel discovery engine; it rewards a relationship you already have, and you still need a way to acquire friends first.

What a real program looks like

Picture a brand with 10,000 friends sending four broadcasts a month: roughly 40,000 messages against quota, landing you in a paid tier and rewarding segmentation so you are not paying to message people who never open. A LINE budget is really two lines — a quota line that scales with friend count and segmentation discipline, and an acquisition line that scales with how fast you want to grow. Three levers fill that second line. Add-to-friend Ads run with the objective of getting users to add your account — the fastest paid way to fill an empty one. Point-of-sale QR is the add prompt at the register, on packaging, and on receipts — why so much of Japanese retail runs on “add us for a coupon.” Sponsored stickers are a distinctively LINE play: a brand pays to distribute a free sticker set users can only download by adding the account. Cost per friend varies enormously — often low hundreds of yen for a consumer brand — so distrust any single number and test.

LINE Ads: the paid acquisition side

LINE Ads is a separate product for buying reach among people who have not added you yet. The main format families are in-chat-list units (card, image, and video at the top of the “Talk” list, LINE’s most-opened surface), video in LINE VOOM (its short-form feed), and placements across LINE NEWS and partner apps — with demographic and interest targeting and creative approval before campaigns run. It is Japan’s answer to paid social and often the most efficient way to build a friend base fast.

One freshness note for 2026: the standalone LINE Ads product is being consolidated into LY Ads Display Ads in spring 2026, pooling LINE’s inventory with Yahoo! JAPAN’s under one auction. Placements and targeting largely carry over, but the dashboard and some format names move — so budget a Japan entry for LY Ads, not the legacy interface. For a full walkthrough of formats, targeting, creative approval, and exactly what the migration changes, see our companion guide to LINE Ads. For overseas advertisers, though, the access rules covered next change what “just run LINE Ads” means in practice.

Can an overseas company run LINE marketing?

This is the question that trips up most non-Japanese teams, and upbeat guides tend to skip it. The split, based on how the platform typically works today:

• Official Account: generally feasible without a Japanese entity, though verification and some features assume Japanese-language operation and a local point of contact.
• LINE Ads: overseas advertisers are typically limited to prepaid accounts — funded in advance rather than billed after the fact — and funding often requires a Japanese credit card. Passing pre-approval for post-pay (billed-in-arrears) accounts is difficult from abroad.

Treat those Ads constraints as typical, not absolute. LINE / LY does not publish its overseas billing and eligibility rules in a public policy page — which is precisely why this reflects operator experience rather than a citable link, so confirm current requirements with a LINE / LY sales rep or a local partner before budgeting. This reality — prepaid funding, a Japanese card, Japanese-language creative approval — is a large part of why overseas companies run LINE Ads through a Japanese partner. It is the same pattern we describe for Yahoo! JAPAN Ads, where local billing and account setup are the real barrier, not the platform itself.

Where LINE fits in a Japan marketing plan

LINE is not a strategy on its own. It is the retention and re-engagement layer of a wider plan, working best when something upstream feeds it new friends:

The takeaway: discovery channels and search create demand, LINE Ads or offline QR convert it into friends, and the Official Account turns friends into repeat customers. Skip acquisition and you have a beautifully built channel with almost no one in it. For which social channels Japanese buyers use and how to pick two or three, see our overview of social media in Japan.

For budget context: per Dentsu’s 2025 Japan Advertising Expenditures report, internet advertising reached 4,045.9 billion yen — 50.2% of total ad spend, over half for the first time. Dentsu does not break out a separate LINE figure, so we will not invent one; the point is that digital now commands more than half of Japanese ad spend, and LINE is a meaningful slice of where consumer attention within it lives.

Choosing a partner to run LINE marketing

Because of the access constraints and Japanese-language operation, most overseas companies run LINE through a local partner, so partner evaluation is part of the job. Questions that separate a real operator from a reseller of tactics:

• How will you build the friend base, not just send to it? A good answer names acquisition sources — Ads, offline QR, on-site prompts — not just “we’ll broadcast weekly.”
• How do you handle overseas-advertiser billing and quota? They should explain prepaid Ads funding, the Japanese-card reality, and how they manage message quota and segmentation without hand-waving.
• Where do data and account ownership sit, and can you report in English? Keep ownership of your audience and ad accounts, and insist on English reporting — many Japanese agencies report only in Japanese and sell narrow ad operations, not the whole program.

Two red flags: a partner who quotes confident, uncited user or “open-rate” statistics (LINE numbers move yearly, and stale figures signal weak diligence), and one who claims the overseas access constraints do not exist. For a broader version of this evaluation, see choosing a digital marketing agency in Japan.

Where LOads fits

In our work with overseas teams, the most common failure is not a bad tactic — it is treating LINE as a broadcast megaphone when its real value is a relationship. Teams open an account, blast the same message to everyone, watch friends drop off and costs climb, and conclude “LINE doesn’t work.” No one designed the acquisition source or the segmentation. The pattern that turns it around is unglamorous: cut broadcast frequency, segment by purchase recency and behavior so each message reaches people likely to act, and let the quota line fall while adds hold steady. LINE punishes the global blast-everything playbook — the specific thing a team used to near-free email sends most often gets wrong.

Here is how we scope this work — our own reference, not an industry standard. LOads is a bilingual Japan marketing partner, founded in 2018 in Fukuoka; we have supported more than 100 companies, and our CEO, Kosuke Tsunawaki, has over 14 years in digital marketing. We work on a fixed monthly fee, with ad budget paid from your own accounts so you keep ownership of the data and audience. As a directional reference: our ad-operations fee runs around 20% of media spend, dropping to 15% above ¥10M/month, with a ¥0 spot diagnostic to start; clients typically run ¥1M or more per month (roughly $6,500–7,000) in media. Your numbers depend on category and goals — orientation, not a quote.

If you are weighing whether Japan and LINE are worth a test, the practical first step is a free pre-consultation: a read on your Japan market opportunity and one strategy call, in plain English — a way to pressure-test the idea before committing budget.

Frequently asked questions

What is LINE marketing, and how is it different from email or WhatsApp marketing?

LINE marketing is reaching and retaining customers through Japan’s dominant messaging app, via a LINE Official Account and, separately, LINE Ads. It resembles email — an opted-in audience of “friends” you message directly — but pricing is by message sent, not list size, and reach in Japan far exceeds any Western messaging channel. Unlike WhatsApp, LINE bundles a wallet, video feed, and ad platform, so it works more like consumer infrastructure than a chat app.

Can a foreign company run LINE Ads or an Official Account without a Japanese entity?

An Official Account is generally feasible without a Japanese entity, though verification and full functionality assume Japanese-language operation. LINE Ads is harder: overseas advertisers are typically restricted to prepaid accounts funded by a Japanese credit card, and post-pay pre-approval from abroad is difficult. Confirm current requirements with a LINE / LY sales rep or a local partner before budgeting.

How much does a LINE Official Account cost, and how does message-count pricing work?

Plans are priced by messages sent, not friend count. A free monthly quota covers on the order of a few hundred messages; beyond it you pay per message, with paid tiers starting around a few thousand yen a month for a larger quota. Cost is therefore controlled by segmentation, not frequency. Because quotas and rates vary by region and change, verify the figures against LINE’s Messaging API pricing documentation before budgeting.

What is the difference between a LINE Official Account and LINE Ads?

An Official Account is your owned channel: friends add you and you message them directly for retention. LINE Ads is a paid channel for acquiring people who have not added you, appearing in the chat list, LINE VOOM, and partner apps. Use Ads or offline QR to build the friend base, then the Official Account to keep and re-engage them.

How many people actually use LINE in Japan?

Per DataReportal’s Digital 2026: Japan report, referencing late 2025, LINE has 99.0 million monthly active users in Japan — 80.5% of the population and 92.6% of internet users — ahead of YouTube, X, and Instagram. Be skeptical of higher, uncited figures from agency blogs; ask which report and which year any number came from.

What are a rich menu, a broadcast, and a step message?

A rich menu is a persistent, tappable image menu pinned to the bottom of the chat, linking to your store, coupons, or booking. A broadcast is a message sent to all friends or a segment at once, drawing down your monthly quota. A step message is an automated, triggered sequence, such as a welcome flow after someone adds you.

Should I hire a Japanese partner to run LINE marketing, and what should I ask?

Most overseas companies do, because of the Japanese-language operation and the Ads billing constraints. Ask how they will build the friend base rather than just message it, how they handle prepaid Ads billing, how they manage quota and segmentation, and where account and data ownership sits. Be wary of partners who quote confident but uncited statistics or who claim the overseas access constraints do not exist.

How does LINE fit alongside Instagram, YouTube, X, and TikTok in Japan?

LINE is the retention and re-engagement layer, not a discovery engine. Use YouTube, Instagram, TikTok, and search to create and capture demand, then LINE Ads or offline QR to convert that attention into friends, and the Official Account to turn friends into repeat customers. An Official Account with no acquisition source upstream is a well-built channel almost no one is in.
