How to Master B2B Media Buying in Japan: A 2026 Guide

Japan is a lucrative market, but for foreign companies, having the right approach is essential. Even if your business has seen success abroad,  success may not translate as quickly in Japan as you might expect.

Media buying in Japan—purchasing advertising space across digital, programmatic, print and out-of-home (OOH) channels—is the most direct route to establishing the credibility you need. However, it presents a unique challenge: unlike Western markets where performance-driven campaigns often yield immediate results, Japan requires a strategy deeply rooted in brand awareness and trust.

In this guide, we explore the specific challenges foreign companies face and share AIM B2B’s best practices for successfully navigating the Japanese media landscape in 2026.

Why is Brand Awareness Critical for Success in Japan?

Before launching sales activation or performance-driven campaigns, you must ensure that Japanese consumers and decision-makers know who you are. In Japan, business culture places a significant emphasis on long-term relationships and brand loyalty.

Many international companies enter Japan expecting immediate conversions from paid search or display ads. However, without a credible reputation, the question “So what?” often kills potential deals. If your brand is not well-known, Japanese buyers—who are generally more risk-averse than their Western counterparts—will hesitate.

The Trust First Rule:

• Western Approach: Generate leads → Build trust through sales process.
• Japanese Approach: Build trust (Awareness) → Generate leads.

Without the initial investment in awareness, you will struggle to connect with decision-makers, no matter how compelling your product is.

How Does Cultural Nuance Impact Media Buying?

Succeeding in Japan requires understanding local behaviors.

The Hybrid Landscape: Digital vs. Traditional

While digital advertising is surging, traditional media remains surprisingly resilient. In the most recent full-year data (2024), while internet advertising grew by 9.6% to nearly 50% of total ad spend, traditional media (TV, radio, newspapers, magazines) actually saw a 0.9% increase—the first growth in three years.

This reliance on print is rooted in Japan’s cultural appreciation for tangible, high-quality content. A full-page ad in the Nikkei newspaper, for example, conveys a level of prestige and stability that a digital banner simply cannot match. For B2B companies, a balanced approach leveraging both traditional authority and digital reach is often the most effective strategy.

Generalist Corporate Culture

In many Japanese corporations, employees rotate through different functions. This means in-house marketing teams may lack the specialized media buying expertise found in Western firms. As a result, agencies such as AIM B2B play a critical role in providing the strategic guidance necessary to navigate these complexities.

What Digital Platforms Matter Most for B2B in 2026?

Japan’s digital landscape is undergoing a massive shift in 2026 with the unification of its two biggest giants.

The New LY Unified Platform (LINE + Yahoo! Japan)

The biggest news in Japanese media buying is the full integration of LINE and Yahoo! Japan ads into a single platform, set to launch in March 2026.

• Connect One Strategy: LY Corporation is unifying its data, allowing advertisers to use Yahoo! search data and LINE user data cross-sectionally for the first time. This means you can retarget users on LINE based on their Yahoo! Japan search history.
• AI Agents: A new AI Agent feature will be integrated into LINE Official Accounts. These agents will autonomous guide customers from inquiry to reservation or purchase, replacing static menus with active, AI-driven support.
• Unified Business ID: Advertisers can now use a single Business ID to manage campaigns across both platforms, simplifying what was previously a fragmented ecosystem.

LINE: The Super App

With more than 98 million monthly active users as of 2025, LINE covers about 80% of the Japanese population. It is not just a chat app; it is digital infrastructure.

• Why it matters: While often viewed as B2C, LINE’s Official Accounts are essential for B2B nurturing. The incoming integration with Yahoo! search data will make B2B targeting significantly more precise.

Video Platforms (YouTube and TVer)

Video is the fastest-growing advertising segment in Japan, jumping 23% year-over-year in the latest report to more than ¥843 billion.

• Why it matters: Japanese audiences value storytelling and aesthetics. High-quality video ads on YouTube or connected TV platforms allow you to convey complex B2B value propositions emotionally and effectively.

LinkedIn vs Local Professionals

While LinkedIn is the B2B gold standard globally, it is still a challenger in Japan.

• Current Status: LinkedIn has grown to about 5 million users in Japan as of December 2025. While smaller than the U.S., it is highly effective for targeting bilingual professionals and executives working at global companies.
• Local Alternatives: For broader B2B reach, platforms such as Facebook (used professionally in Japan) and local business card networks such as Sansan/Eight are often part of the mix.

TV & Connected TV: The Trust Builders

While digital is efficient, Television remains the king of credibility in Japan. With more than 80% of the population watching TV daily, it offers unmatched reach for building mass awareness.

The Landscape:

• Linear TV: Dominated by five key commercial networks in Tokyo (NTV, TV Asahi, TBS, Fuji TV, TV Tokyo) plus the public broadcaster NHK.
• Connected TV (CTV) / Catch-up TV: TVer, a platform aggregating content from more than 100 commercial stations, now boasts 41 million monthly users and 490 million monthly views.
  • Why it matters for B2B: TVer allows for programmatic buying with 96% viewing completion rates and precise targeting (e.g., by occupation or business district) that linear TV cannot offer.

Buying Methods:

• Time Ads (Sponsorship): You sponsor a specific program. Great for branding but typically requires a six-month commitment.
• Spot Ads: Buying widely across a station’s schedule. Flexible (minimum one week) and good for quick reach.
• Targeting Ads (TVer): The digital-like option. You can buy 6–60 second slots on high-quality programs with granular targeting.

The Challenges:

• High Barriers to Entry: To buy terrestrial TV, you generally must have a legal entity in Japan.
• Strict Censorship: Client censorship (vetting) is rigorous. Stations review not just the ad but the company itself. This process can take 1–2 months, so last-minute campaigns are impossible.
• Competitive Exclusion: If a competitor is already sponsoring a program, you may be blocked from buying airtime on that same show.

OOH (Out-of-Home) and DOOH (Digital Out-of-Home): Dominating the Commute

In Tokyo, millions of professionals commute via a dense web of rail lines every day, making Transit Advertising a B2B goldmine.

The Landscape:

• Transit Ads: Ads inside trains and at stations are highly effective because they capture a captive audience during their daily commute.
• Digital Growth (DOOH): While static billboards are stable, Digital OOH is growing rapidly, doubling its market share over the last decade. Digital screens are now common in stations, taxis and elevators—perfect for reaching decision-makers in transit.

The Challenges:

• Fragmented Ownership: Unlike markets with one or two dominant vendors, Japan’s OOH market is scattered. While rail ads are handled by railway subsidiaries, traditional outdoor boards are owned by numerous small vendors, making consolidated data difficult to obtain.
• Rigid Booking System: Prime locations are often owned by transport companies (such as JR or Metro) who operate on legacy systems. Bookings follow a First-Come, First-Served model and often need to be made 2–3 months in advance.
• Arbitrary Standards: Media owners (often the railway companies) are not marketing pros—they are infrastructure operators. They have strict, sometimes arbitrary standards for creatives. If your creative is flagged, they can pull it immediately.
• Financial Risk: If your ad is pulled for not meeting standards, you are often still liable to pay for the spot. Furthermore, because bookings are fixed, you rarely have the flexibility to move a campaign if dates shift.

What Common Mistakes Do Foreign Companies Make?

International companies often falter by applying a one-size-fits-all global strategy to Japan.

• Rushing to Performance Marketing: Launching direct response campaigns (such as Book a Demo) before building awareness often leads to high CPAs (Cost Per Acquisition) and low conversion rates. You must educate the market on the problem you solve before selling the solution.
• Direct Translation instead of Transcreation: Using tools such as Google Translate or literal translations for ad copy is a major pitfall. Japanese is a high-context language; content must be transcreated to resonate with local cultural norms and emotional triggers.
• Overestimating Digital Sophistication: While Japan is high-tech, its digital advertising infrastructure can be different. Some local publishers offer fewer targeting options or less granular metrics than Western platforms. However, the March 2026 LY integration aims to solve this by offering “Business Manager Insight” to visualize cross-platform data.
