How to Advertise in Japan: A Paid Media Guide for Foreign Companies

Running your global ad account in Japan usually means wasted spend: the messaging doesn't resonate, the landing pages don't convert, and the channel mix isn't tuned to how Japanese buyers respond. Here's how to advertise in Japan so budget turns into pipeline.

But first, a caveat we give every client: paid media isn't always the right move. We start from your goal — leads or brand, entering cold or scaling something that already works — hear out your funnel and constraints, and recommend the mix that fits. Sometimes that's paid search; sometimes it's SEO and content, an industry event or webinar, or email. We're media-neutral and we don't just run PPC — we'll tell you honestly if your budget belongs somewhere other than ads.

1. Which ad platforms actually matter in Japan?

For B2B: Google, LinkedIn, Microsoft Ads (Bing), and YouTube — with the mix depending on your buyers.

A quick orientation:

• Google Ads — search and display. The default starting point; Google leads search and dominates mobile.
• LinkedIn — can reach specific decision-makers by job title, industry, and company size, but be realistic: for the Japan market the audience is smaller and pricier, and it's often less effective than its B2B reputation suggests. We use it selectively, not as a primary lead engine.
• Microsoft Ads (Bing) — strong on the Japanese office desktop, less competitive, and it can layer LinkedIn profile targeting (more below).
• Japan-specific DSPs & PR media — domestic demand-side platforms (including business-card/meishi-data and industry/role targeting) and PR-driven advertising. Uniquely Japanese, and easy to miss from outside (more below).
• YouTube — for awareness and demand creation.
• LINE and consumer social — powerful for B2C, but not a B2B workhorse.

We plan media-neutral: the right mix is the one that fits your funnel, not the one that pays the agency the most.

A quick note on LinkedIn

In Japan, LinkedIn ads often just burn budget — you pay a premium per click, but the results don't follow.

LinkedIn can reach foreign-affiliated (gaishikei) audiences, but adoption among Japanese domestic (nikkei) companies and their decision-makers is low. Foreign teams often don't realise this, run their usual LinkedIn campaigns, and watch the clicks cost a lot while pipeline doesn't materialise. If your buyers are Japanese firms, put that budget into what actually works here — Japanese search (Google and Bing), SEO and content, email, industry media, events, and the Japan-specific ad platforms below — and keep LinkedIn only for genuinely foreign-affiliated targets.

Japan's own DSPs: the channels global teams never find

Japan has its own demand-side platforms (DSPs) that don't exist anywhere else — and using them well is one of the clearest signs a partner truly knows this market.

If your global playbook (or LinkedIn) hasn't delivered, Japan-specific DSPs are often exactly where the results are:

• Business-card (meishi) data DSPs. Exchanging business cards (meishi) is a standard part of Japanese business — and some Japanese ad platforms can target using that data. MicroAd's B2B DSP Shirareru targets by company attributes and job role, drawing on audience data linked to Eight, Japan's leading business-card app; ADMATRIX DSP targets companies and job titles through office-IP data. It's a capability that essentially only exists in Japan, and global teams have no idea it's there.
• Industry- and role-targeted DSPs. Domestic platforms that let you narrow by specific industry or job title in ways global tools simply can't in Japan.

These DSPs are precisely what a global team can't discover from outside Japan — and where a partner who lives in this market earns its keep. If results haven't come from your usual channels, the right Japanese DSP, matched to your audience, is often the difference.

We also run PR- and media-driven advertising through Japanese outlets to build the third-party credibility Japanese buyers value — a useful complement to the DSPs above.

2. Is it just Google, or do Bing and Yahoo! matter?

Google leads, but for B2B you shouldn't ignore Bing.

Google leads search in Japan and dominates mobile, and Yahoo! JAPAN's organic results run on Google's technology — so Google covers most organic search. For paid, though, Microsoft Ads reaches Bing, which carries real weight on the Japanese office desktop, where a lot of B2B research happens (see Japanese SEO for Foreign Companies for the full picture). Yahoo! JAPAN also runs its own ad inventory, which can be a secondary option, but it's not where we'd start for most foreign B2B advertisers.

Note on figures: public search-share numbers vary by source and method, so we treat them directionally and confirm the real mix with your analytics.

3. Why do global ad campaigns underperform in Japan?

Because they're often run by the global team rather than a Japan specialist — launched with literally translated ads and landing pages that don't match how Japanese buyers evaluate and convert.

In a large share of cases, a global marketer sets up and runs Japan PPC using directly translated creative, and the budget quietly drains with little to show for it. Getting it right means customizing for Japanese targets and Japanese buyer behavior — not porting the global account with the language switched. The three usual culprits:

• Creative that was translated, not transcreated. Literal translations feel foreign and under-persuade (see Localization vs. Transcreation).
• Landing pages built for another market. Japanese buyers expect different information density, trust signals, and structure. A page that converts in the US often won't in Japan.
• Optimizing to the wrong metric. Chasing clicks or impressions instead of qualified leads and pipeline burns budget on the wrong traffic.

Fix the creative and the landing page first; the media almost always performs better afterwards.

4. Should we run Microsoft (Bing) Ads?

For B2B, it's usually worth testing.

Many Japanese offices default to Bing on the desktop, yet most competitors ignore it — so the auctions are less crowded and click costs tend to run lower than Google Ads. Microsoft Ads can also target by LinkedIn profile — company, industry, and job function — which can help narrow to decision-makers (Microsoft Advertising); availability varies by market, so we confirm what's enabled for Japan-targeted accounts before building the plan.

The pragmatic move: import your existing Google campaigns into Microsoft Ads, run a small B2B test on high-intent keywords, and let the numbers decide.

5. How should we think about budget and cost-per-lead?

Start small, learn, then scale — and set cost-per-lead expectations by channel and intent, not by a single number.

Japan CPLs vary widely by industry, keyword intent, and competition, so a fixed benchmark is misleading. A workable approach:

1. Test high-intent keywords (branded, comparison, problem-solution) across Google, LinkedIn, and Microsoft Ads.
2. Measure cost-per-qualified-lead, not cost-per-click.
3. Scale what produces qualified pipeline, and cut what doesn't.

For lead-generation programs, we can also combine guaranteed-lead media with PPC and email to reduce the risk of a new market under-delivering.

6. How do we measure success?

Leads, cost-per-lead, and pipeline — reported in English for HQ.

Impressions and clicks are inputs, not outcomes. Tie your campaigns to qualified leads and downstream pipeline, and report on those in a way headquarters can act on (see How to Explain Japan Timelines & Budget to Your HQ). That's what lets you defend and grow the Japan ad budget internally.
