In Japan, LINE is not just a messaging app — it is the digital infrastructure of daily life. With 95 million monthly active users in a country of 125 million, LINE’s penetration is extraordinary, cutting across every age group, income level, and region. In Thailand, the story is nearly identical: 54 million monthly active users in a population of 72 million. No other platform comes close in either market. Not Facebook. Not Instagram. Not X.

For Singapore businesses targeting Japanese or Thai consumers — whether through tourism, e-commerce, or market entry — LINE is not optional. It is the primary channel through which these consumers communicate, consume content, make purchases, and interact with brands. Ignoring LINE means ignoring the dominant digital platform in two of Asia’s most valuable consumer markets.

This guide covers everything you need to know about LINE advertising and marketing from Singapore — from setting up an Official Account to running paid campaigns, with specific guidance on the differences between the Japanese and Thai markets. For hands-on support, our LINE advertising services page outlines how we help Singapore businesses succeed on this platform.

What Is LINE: The Super-App Ecosystem

LINE started as a messaging app born from necessity — developed in the aftermath of the 2011 Japanese earthquake when telecommunications infrastructure was unreliable. It has since evolved into a comprehensive super-app ecosystem that touches nearly every aspect of digital life in Japan and Thailand.

Beyond Messaging

LINE’s ecosystem includes:

  • LINE Messenger: The core messaging platform — text, voice calls, video calls, group chats. This is the default communication tool in both markets, used by businesses and individuals alike.
  • LINE VOOM: A social media feed (formerly LINE Timeline) for short-form content, similar to Instagram Stories or TikTok. Users browse VOOM for entertainment, brand content, and creator updates.
  • LINE Pay: A mobile payment system widely accepted across Japan and Thailand. Integrated with the messaging experience for seamless peer-to-peer and merchant transactions.
  • LINE Shopping: An integrated e-commerce platform where users browse, compare, and purchase products without leaving the LINE ecosystem.
  • LINE Points: A loyalty and rewards system that users earn through engagement, purchases, and promotions. Points can be redeemed across the LINE ecosystem and at partner merchants.
  • LINE News, LINE Manga, LINE Music: Content verticals that keep users within the ecosystem for hours daily, creating additional advertising inventory and brand touchpoints.

This ecosystem matters for advertisers because LINE users are not just messaging — they are shopping, reading, paying, and consuming content. Every touchpoint is a potential advertising surface, and the data generated across these services enables sophisticated targeting that standalone messaging apps cannot match.

LINE for Business: Core Products

LINE’s business tools have matured into a comprehensive marketing platform. Understanding the core products is essential before diving into advertising specifics.

Official Accounts

A LINE Official Account is the foundation of any brand’s LINE presence. It functions as your brand’s profile on LINE — users “add” your account as a “Friend,” and you can then communicate with them directly through the messaging interface. This creates a direct, owned communication channel with your audience, similar to an email list but with dramatically higher open and engagement rates.

LINE Ads Platform

LINE’s self-serve advertising platform allows you to run display, video, and native ads across the LINE ecosystem. Ads appear in the chat list, VOOM feed, LINE News, LINE Shopping, and partner apps. The platform offers campaign objectives spanning awareness, consideration, and conversion.

LINE Points Ads

A unique format where users earn LINE Points for engaging with your brand — watching a video, adding your Official Account, completing a survey. This incentivised engagement model drives rapid audience building and is particularly effective for new market entrants who need to build a Friends base quickly.

LINE VOOM

The social content feed where brands and creators publish short-form content. VOOM content can be promoted through LINE Ads to reach users beyond your existing Friends list. Video content on VOOM is increasingly important as LINE invests in competing with TikTok and Instagram Reels in local markets.

Setting Up an Official Account from Singapore

LINE offers three account tiers, each with different capabilities and pricing structures.

Account Types and Pricing

Feature Free Plan Light Plan Standard Plan
Monthly cost Free JPY 5,000 / THB 1,198 JPY 15,000 / THB 2,998
Free messages per month 200 5,000 30,000
Additional messages Not available Available at additional cost Available at additional cost

Rich menus Yes Yes Yes
Analytics Basic Full Full
API access Yes Yes Yes

Setup Process for Overseas Businesses

Singapore businesses can set up LINE Official Accounts for both the Japanese and Thai markets. The process differs by market:

  • Japan: Registration through LINE for Business portal. Overseas businesses can register directly but may need a Japan-based contact or representative for certain verified account features. Documentation requirements include business registration and identification of the account administrator.
  • Thailand: Registration through LINE Official Account Thailand portal. Similar documentation requirements. Thai language support for account setup is generally more straightforward for overseas businesses than the Japanese portal.

For both markets, we recommend starting with the Free plan to test and learn, then upgrading to Light or Standard as your Friends list grows beyond the free message allocation. The cost of additional messages beyond your plan’s allocation is approximately JPY 3 per message in Japan.

Advertising Formats and Pricing

LINE Ads Platform offers multiple ad formats, each suited to different campaign objectives and creative approaches.

Display Ads

Static image ads that appear across LINE’s placement network — the chat list (Smart Channel), VOOM, LINE News, LINE Shopping, and LINE partner apps. These are versatile workhorse formats suitable for awareness through conversion campaigns. Recommended image sizes are 1080 x 1080 pixels (square) and 1200 x 628 pixels (landscape).

Video Ads

Video placements across the same inventory as display, with auto-play in-feed. Short videos (6–15 seconds) perform best for awareness, while longer formats (up to 60 seconds) work for consideration-stage content. Vertical video (9:16) is recommended for VOOM placements.

Smart Channel

Premium placement at the top of the LINE chat list — the most viewed screen in the app. This is LINE’s highest-visibility ad placement. Users see your ad every time they open LINE to check their messages. CPM rates for Smart Channel are higher than other placements but justify the premium through exceptional reach and visibility.

VOOM Ads

Native ads within the VOOM social feed. These blend with organic creator and brand content, appearing as users scroll through their feed. Both image and video formats are supported. VOOM ads are effective for engagement-focused campaigns and younger demographics who spend significant time in the feed.

Sponsored Stickers

One of LINE’s most unique and powerful ad formats. Brands create custom sticker packs that users download for free (in exchange for adding the brand’s Official Account as a Friend). Stickers become part of users’ daily conversations, providing ongoing brand exposure every time they are used. A single sponsored sticker campaign can generate millions of Friends additions. Pricing is premium — typically JPY 10–30 million for Japan and THB 1.5–5 million for Thailand — but the cost per Friend acquired and the ongoing organic exposure can make it highly cost-effective for brands with sufficient budget.

Typical Pricing Benchmarks

Metric Japan Thailand
CPM (display) JPY 400–800 (SGD 3.50–7.00) THB 30–80 (SGD 1.20–3.20)
CPC JPY 30–100 (SGD 0.26–0.87) THB 2–8 (SGD 0.08–0.32)
Cost per Friend (add) JPY 100–400 (SGD 0.87–3.50) THB 5–30 (SGD 0.20–1.20)
Minimum daily budget JPY 1,000 (SGD 8.70) THB 500 (SGD 20)

Thailand’s lower CPMs make it significantly more cost-effective for reaching large audiences, while Japan’s higher costs reflect the premium purchasing power of its consumer base.

Targeting Capabilities

LINE’s advertising platform offers robust targeting options built on first-party data from its vast user ecosystem.

Demographic Targeting

Target by age, gender, location (prefectures in Japan, provinces in Thailand), and operating system. Location targeting is particularly granular in Japan, allowing targeting down to municipal level.

Interest and Behavioural Targeting

LINE’s interest categories are built from user behaviour across the ecosystem — content consumption on LINE News, browsing on LINE Shopping, sticker usage patterns, and more. Categories include fashion, beauty, technology, food, travel, automotive, finance, entertainment, and dozens of sub-categories.

Lookalike Audiences

Create audiences similar to your existing customers or Friends list. LINE’s lookalike modelling leverages cross-ecosystem behavioural data, often delivering stronger performance than lookalikes on platforms with more limited first-party data. Lookalike audience sizes can be adjusted from 1% (most similar) to 15% (broader reach).

Retargeting

Retarget users who have visited your website (via LINE Tag pixel), engaged with your Official Account, opened your messages, watched your videos, or interacted with previous ads. Website retargeting requires installing the LINE Tag on your site — a simple JavaScript snippet similar to the Facebook Pixel.

Audience Match

Upload your existing customer data (phone numbers or email addresses) to create custom audiences on LINE. Match rates in Japan are particularly high given LINE’s near-universal penetration. This is powerful for re-engaging existing customers or creating exclusion audiences to focus spend on acquisition.

Content Strategy for LINE

Effective LINE marketing requires a content strategy that leverages the platform’s unique communication features. Unlike broadcast social media, LINE is fundamentally a conversational platform — your content lands directly in users’ message inboxes alongside messages from friends and family.

Broadcast Messages

Messages sent to your Friends list are the core engagement tool. Keep these concise, valuable, and infrequent enough to avoid fatigue. Best practices include limiting broadcasts to 2–4 per month, leading with value (offers, useful information, exclusive content), and using rich media formats (images, cards, carousels) rather than plain text. Message open rates on LINE typically range from 50–70% — dramatically higher than email — but unsubscribe rates also respond quickly to over-messaging.

Rich Menus

The rich menu is a persistent visual menu at the bottom of your Official Account chat screen. It functions as a mini-website navigation within LINE — linking to your product catalogue, customer service, promotions, store locator, loyalty programme, or external website. Design your rich menu to surface your most important customer actions. Update it seasonally or for campaigns to keep it fresh.

Auto-Reply and Chatbot

LINE’s auto-reply and chatbot functionality allows you to provide instant responses to common queries, guide users through product selection, handle reservations, and provide customer support 24/7. For Singapore businesses serving Japanese or Thai markets, an automated system that handles basic enquiries in the local language is essential for managing time zone differences.

VOOM Content

Publish regular content to VOOM to maintain visibility with your Friends and reach new users through the algorithmic feed. Short-form video, behind-the-scenes content, product showcases, and user testimonials perform well. VOOM content should be lighter and more entertaining than broadcast messages — it competes with creator content in a scrollable feed environment.

Stickers and Creative Assets

Custom branded stickers — even modest creator sticker packs outside the premium sponsored tier — can significantly boost brand recall. LINE’s sticker culture is unique: users communicate emotions and reactions through stickers in everyday conversations. A well-designed sticker pack that becomes part of users’ regular communication toolkit provides organic brand impressions that no other ad format can replicate. For comprehensive social strategy across multiple platforms, see our social media marketing services.

LINE for E-Commerce

LINE has built substantial e-commerce infrastructure that Singapore businesses can leverage for selling into Japan and Thailand.

LINE Shopping

LINE Shopping aggregates products from partner e-commerce platforms and independent shops. In Thailand, LINE Shopping (via LINE MyShop) is a particularly important channel, allowing businesses to set up a storefront within LINE and sell directly through chat commerce. The integration with LINE Pay simplifies the checkout experience.

Product Catalogue and Shopping Ads

Upload your product catalogue to LINE’s system to enable dynamic product ads and shopping-focused campaigns. These ads automatically showcase relevant products to users based on their browsing behaviour, similar to Facebook’s Dynamic Product Ads. This is highly effective for e-commerce businesses with large product catalogues.

LINE Points Loyalty

Integrate LINE Points into your customer loyalty strategy. Award Points for purchases, engagement actions, or referrals. Users can redeem Points across the LINE ecosystem, creating a compelling incentive structure. In Japan especially, Points-based loyalty is deeply embedded in consumer culture — LINE Points, Rakuten Points, and T-Points are all widely used, and consumers actively seek opportunities to earn them.

Japan vs Thailand: Key Differences

While LINE dominates both markets, the user behaviour, regulatory environment, and marketing approach differ significantly between Japan and Thailand.

User Behaviour

Dimension Japan Thailand
Communication style Formal, polite, indirect. Content must respect Japanese communication norms. Casual, playful, expressive. Humour and warmth resonate.
Purchase behaviour Research-intensive, quality-focused, brand-loyal. Longer consideration cycles. Promotion-driven, social-proof influenced, faster purchase decisions.
Sticker usage Extremely heavy. Stickers are a primary communication tool, not just decoration. Very heavy. Similar sticker culture with local character preferences.
Chat commerce Growing but still secondary to established e-commerce platforms (Amazon, Rakuten). Mainstream. Many Thai consumers prefer buying through chat over traditional e-commerce.

Regulatory Considerations

Japan — APPI (Act on the Protection of Personal Information): Japan’s privacy law has been strengthened significantly in recent years. It requires explicit consent for data collection, purpose limitation, and provides individuals with rights to access, correct, and delete their data. Cross-border data transfer requires ensuring adequate protection standards. LINE advertising in Japan must comply with APPI, the Act against Unjustifiable Premiums and Misleading Representations, and industry-specific regulations (particularly strict in pharmaceuticals, financial services, and food).

Thailand — PDPA (Personal Data Protection Act): Thailand’s PDPA, fully enforced since 2022, mirrors GDPR principles. It requires lawful basis for data processing, consent mechanisms, and data subject rights. Marketing communications require explicit opt-in consent. Penalties for non-compliance can reach THB 5 million per violation. For Singapore businesses, compliance with both Singapore’s PDPA and Thailand’s PDPA is required, and while they share similar principles, the specific requirements differ.

Localisation Requirements

Both markets demand thorough localisation — not just translation. Japanese consumers expect native-level Japanese with appropriate formality levels (keigo for formal communications, casual for social content). Thai consumers expect Thai-language content with culturally appropriate imagery and references. Machine translation is immediately noticeable and damages brand credibility in both markets. Invest in native-speaking copywriters and cultural consultants. Our international SEO services include multilingual content strategy for Asian markets.

Measuring Success

LINE provides comprehensive analytics for both Official Accounts and advertising campaigns. Understanding which metrics matter at each stage is essential for optimising your investment.

Official Account Metrics

  • Friends growth: Net new Friends (additions minus blocks) is the foundational metric for your LINE presence. Track both absolute growth and the cost per Friend acquired through various channels.
  • Message open rate: The percentage of Friends who open your broadcast messages. Healthy rates range from 50–70%. Declining open rates signal content fatigue or audience quality issues.
  • Click-through rate: The percentage of recipients who click links within your messages. Benchmark CTR is 5–15% for well-targeted broadcasts with compelling offers.
  • Block rate: The percentage of Friends who block your account. Keep this below 3% per broadcast. Rising block rates require immediate attention to message frequency and content relevance.

Advertising Metrics

  • Cost per Friend: For Friend acquisition campaigns, this is the primary efficiency metric. Benchmark against the pricing table above and optimise creative and targeting to reduce this over time.
  • Conversion rate and CPA: For website conversion campaigns, track through the LINE Tag pixel. Compare LINE’s CPA against other channels to evaluate relative efficiency.
  • ROAS (Return on Ad Spend): For e-commerce campaigns, track revenue generated per dollar of LINE ad spend. This requires proper conversion tracking setup including revenue values.
  • Frequency and reach: Monitor ad frequency to prevent fatigue. LINE recommends keeping frequency below 8 impressions per user per month for most campaigns.

Attribution Considerations

LINE’s role in the customer journey often extends beyond last-click attribution. A user might see your LINE ad, add your Official Account, receive several broadcast messages over weeks, and then convert through a different channel. Consider implementing multi-touch attribution or tracking assisted conversions to fully understand LINE’s contribution to your marketing mix. For Naver advertising targeting South Korea alongside LINE for Japan and Thailand, a unified cross-platform attribution model becomes even more important.

Frequently Asked Questions

Can I run LINE ads targeting Japan and Thailand from Singapore?

Yes. LINE’s advertising platform is accessible to overseas advertisers for both markets. You can set up ad accounts targeting Japan through LINE for Business (Japan) and Thailand through LINE for Business (Thailand). The platforms are separate — you need distinct accounts for each market. Ad management interfaces are available in English, though some features and documentation may be primarily in Japanese or Thai. Payment can be made via credit card in most currencies. Many Singapore businesses find it practical to work with an agency that has established accounts and relationships with LINE’s sales teams in both markets.

How much budget do I need to start advertising on LINE?

Minimum daily budgets start from approximately JPY 1,000 (SGD 8.70) for Japan and THB 500 (SGD 20) for Thailand. However, meaningful test campaigns require larger allocations — we recommend at least SGD 1,500–3,000 per month per market for initial testing. This allows sufficient data for optimisation across multiple audience segments and creative variations. For sponsored sticker campaigns, the entry cost is substantially higher (JPY 10+ million for Japan), making them suitable for brands with established budgets. A phased approach — starting with Official Account and organic content, then adding targeted ads, and eventually considering premium formats — is the most capital-efficient path for new market entrants.

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

The Official Account is your brand’s presence on LINE — users follow it (“add as Friend”) and you can send them messages directly. It is an owned channel, similar to an email list. The Ads Platform is paid advertising — display, video, and native ads that appear across LINE’s ecosystem to users who are not necessarily your Friends. The two work together: you use ads to drive Friend additions and awareness, then nurture those Friends through Official Account messaging. Think of the Ads Platform as the acquisition engine and the Official Account as the engagement and retention channel. Both are managed through separate but linked dashboards within LINE’s business tools.

How do sponsored stickers work, and are they worth the investment?

Sponsored stickers are custom-branded sticker packs offered to users for free, typically in exchange for adding your Official Account. Users download the pack and then use the stickers in their daily conversations — your brand characters appear in chats between friends, family, and colleagues, generating organic impressions with every use. A successful sponsored sticker campaign in Japan can generate 5–15 million Friend additions and hundreds of millions of sticker sends. The investment is significant (JPY 10–30 million), but when measured by cost per Friend and ongoing organic impressions, it often outperforms other acquisition channels. They are best suited for brands with mass-market appeal, sufficient budget for the upfront investment, and a plan to monetise the acquired Friends through ongoing Official Account marketing.

Do I need separate strategies for Japan and Thailand?

Absolutely. While the LINE platform is structurally similar in both markets, the audiences, cultural contexts, competitive landscapes, and regulatory environments are fundamentally different. Creative assets need to be developed natively for each market — a Japanese campaign translated into Thai will underperform a Thai-native campaign, and vice versa. Messaging frequency preferences differ, promotional mechanics that work in Thailand (flash sales, deep discounts) may not translate to Japan (where quality positioning and loyalty rewards resonate more), and regulatory compliance requires market-specific expertise. Treat them as two separate campaigns that happen to share the same platform, not as one campaign with two translations.
