Your Business on LINE: How to Reach a Larger Audience in Japan

In Japan, where LINE dominates as the primary messaging app, businesses have an unparalleled opportunity to engage with users through targeted advertising. With more than 97 million monthly active users, LINE has emerged as a necessary tool for communication across all segments. By using LINE Ads, businesses can efficiently advertise their products and services to an actively engaged user base.

This blog explores into the ways businesses can employ LINE Ads strategically to get customers, promote brand awareness, and encourage substantial engagement.

Why LINE Ads Are Essential for Businesses

1. Unmatched Visibility

In contrast to conventional digital advertisements that need consumers to click or search actively, LINE Ads are naturally embedded in users’ daily routines. As they converse with friends or browse notifications, such ads organically show up within their feeds, which makes them difficult to ignore.

2. Precise Audience Targeting

LINE Ads tap into user information, including:

-Registration data (age, gender, region)

-Interests and web pages visited

-Past interactions with merchants

This makes it possible for businesses to deliver hyper-targeted campaigns that engage the intended recipients at the correct moment.

3. Higher Engagement Rates

Since LINE Ads are seen within a trusted space—where customers already interact with friends, loved ones, and brands—they exhibit greater rates of engagement than common advertisements.

Where Do LINE Ads Show Up

1. LINE Chat List Ads

One of the most potent placements, these ads show up in the chat list—just where users view their messages. This guarantees highest visibility as users often check this area.

2. LINE Timeline Ads

Like social media timelines, LINE’s timeline enables businesses to insert sponsored posts that easily mix with native content. It is suitable for businesses that aim to build brand awareness using captivating images and videos.

3. LINE News & Webtoon Ads

For entertainment and news readers, ads can be targeted in LINE News and LINE Webtoon—well-liked features in the app.

4. Talk Head View (Premium Placement)

For big promotions, Talk Head View provides premium ad placement at the top of the chat list for maximum visibility.

Best Practices for Running Effective LINE Ads

1. Use High-Impact Visuals

Since LINE Ads tend to come in small sizes, companies need to focus on simple, good-looking content. Keep text brief and make sure images are high contrast and legible on mobile phones.

Suggested Ad Sizes:

Small Image (600px × 400px) – Suitable for chat list ads

Square (1080px × 1080px) – Suitable for timeline ads

Card (1200px × 628px) – Suitable for news and webtoon ads

2. Write Brief, Engaging Copy

With limited ad space, short and direct messaging is crucial. Highlight a key benefit or offer within the first few words to capture attention quickly.

Example:

Weak: “Our online store has launched many new items! Check them out now!”

Strong: “50% OFF Today Only! Shop Now!”

3. Leverage Retargeting and Lookalike Audiences

LINE Ads enable businesses to retarget users who have visited their site, app, or previous advertisements. You may also use lookalike audiences to target users similar to those in your customer base.

4. Optimize for Mobile Conversions

Being a mostly mobile app, companies should have their landing pages as fast-loading as possible and also mobile-friendly. A long, complicated checkout or slow-to-load site will hugely lower the rate of conversion.

5. Test & Optimize for Best Performance

To achieve maximum ad performance, companies must conduct A/B tests on various creatives, placements, and messaging. Tracking metrics such as CTR (Click-Through Rate) and CVR (Conversion Rate) optimizes campaigns for improved performance.
