Marketing in Japan: a practical starting point for overseas teams
Hand someone the job of marketing in Japan and most of what they will find comes in two flavors: cultural mystique, or a channel list copied from the home market with the names swapped. Neither answers the question you actually have, which is what to do first, and what to spend on.
Updated 2 September 2026 with a section on what advertising costs in Japan: platform minimums, top-of-page bids for ten Japanese B2B queries, and the costs behind the media bill.
Japan's advertising market in 2025: the shape, not the folklore
The short version of this article: check Japanese search demand first, build one Japanese page on what you find, wire measurement, run a small paid pilot, and only then decide the content programme. What follows is the market data that order rests on, the channels, what advertising actually costs, and the order itself.
Japan's advertising market is large, measured annually, and increasingly digital. In 2025, total advertising expenditure reached a record high, and internet advertising crossed a line it had never crossed before: "accounting for more than half of total advertising expenditures for the first time at 50.2%," as Dentsu's annual study puts it (Dentsu, March 2026 release, confirmed 2 September 2026).
Two things follow. First, a digital-first entry into Japan is not a budget compromise; it is how the majority of the market now spends. Second, the other half still exists. Television, newspapers, magazines and radio together still took 2,298.0 billion yen in 2025, down 1.6% (Dentsu, same release), and out-of-home, direct mail and events sit on top of that. If you sell to consumers at scale, those channels are part of the conversation. For most overseas B2B and SaaS teams, they are not where the first budget goes.
The channels, and what each one is for
Search
This is where Japanese buyers compare vendors, and it is Google-first: Yahoo! JAPAN's search service runs on Google's engine, by its operator's own statement, and Google's share on phones has been large and stable for the past year. The device-level data, with sources, is in Japanese search engines: what the data actually shows. AI-generated search summaries draw on the same foundations, so work done for search is not lost when the answer arrives as a summary.
Paid search
The fastest way to put a Japanese message in front of a Japanese buyer and find out what happens. Google Ads and Yahoo! JAPAN's ad products are separate systems even though organic search shares an engine, which is why paid search is where the Yahoo! JAPAN question genuinely matters. The U.S. International Trade Administration's commercial guide lists search advertising on Google and Yahoo! among the standard ways to reach Japanese customers (ITA country commercial guide, updated November 2025, confirmed 6 August 2026).
LINE
LINE is the messaging layer of Japanese daily life: 100 million monthly active users in Japan, 81.3% of the population, by LY Corporation's own count as of 31 March 2026. What that means for you depends on what you sell. For consumer businesses, LINE official accounts are a serious retention and repeat-purchase channel. For B2B, LINE is more often a communication and support surface than an acquisition channel; acquisition usually starts at search.
Social and video
Social and video are the fastest-growing corners of the digital half: social ad spend grew 18.7% in 2025, and video advertising passed one trillion yen for the first time since estimates began (Dentsu, same annual study). Which platform matters shifts by category, and the honest position is that a market-level chart cannot make that call for you. Pick the platform where your category's buyers demonstrably spend attention, and check the assumption with your own measurement.
Everything that is not digital
Trade media, exhibitions and long relationship-building remain a normal part of B2B life in Japan. The ITA guide's observation is blunt: "Relationships are critical in Japan, and customers tend to be loyal to these long-term, well-maintained relationships." How much weight that carries in your plan depends on industry and deal size, not on a rule about the country. The practical implication is narrower than the folklore: marketing that produces a first conversation is worth more here than marketing that produces clicks.
What advertising costs in Japan
The question behind most budget conversations is simpler than the answer it usually gets: is there a minimum, what does a click cost, and what else is on the bill besides the media. Here is what can be said with sources, and where a number would be invented.
There is no minimum to start
None of the three main platforms sets a minimum spend. Google's pricing page says bidding amounts "are ultimately up to you", and its Help pages describe the daily budget as the amount you are willing to spend on average each day (Google Ads pricing and Help, confirmed 2 September 2026). LINE Ads' own FAQ answers the minimum-spend question with "there is no minimum" and no set-up fee, then adds a caveat worth keeping: with too small a budget, the platform may not accumulate the data it needs to improve results (LY Corporation, LINE Ads FAQ, Japanese, confirmed 2 September 2026). LINE Yahoo Ads, the platform formerly sold as Yahoo! JAPAN Ads, gives the same answer: no minimum, set the amount to your budget, and allow one to three business days from account creation to first delivery (LY Corporation, LINE Yahoo Ads FAQ, Japanese, confirmed 2 September 2026).
So the monthly minimums quoted elsewhere are not platform rules. They are what a particular agency needs to make a client worth managing. That is useful to know when you compare agencies, and irrelevant when you plan a pilot you run yourself.
What a click costs: ten Japanese B2B queries
We ran ten Japanese business queries through Google Keyword Planner from an active advertising account, targeting Japan, for the twelve months to July 2026. The figure the planner gives is the range of bids that placed ads at the top of the page, not what any advertiser actually paid, and it moves. It is still the closest thing to a public price list for a Japanese click.
| Query (English gloss, Japanese as searched) | Average monthly searches | Top-of-page bid, low (yen) | Top-of-page bid, high (yen) |
|---|---|---|---|
| Recruitment agency 人材紹介 会社 | 3,600 | 570 | 4,344 |
| SEO company SEO対策 会社 | 590 | 691 | 4,118 |
| System development company システム開発 会社 | 720 | 514 | 2,469 |
| Attendance management system 勤怠管理システム | 8,100 | 281 | 2,413 |
| Translation company 翻訳 会社 | 1,900 | 301 | 2,118 |
| CRM comparison CRM 比較 | 260 | 609 | 2,052 |
| Accounting software, corporate 会計ソフト 法人 | 390 | 250 | 1,840 |
| Project management tool プロジェクト管理ツール | 2,400 | 312 | 1,765 |
| Website production company ホームページ制作 会社 | 2,900 | 327 | 1,375 |
Three things stand out. The high end runs from about 1,400 yen to over 4,300 yen per click, and the low end from 250 to about 700 yen, so "what does a click cost in Japan" has no single answer even inside B2B. Queries that name a type of supplier, the ones ending in 会社, "company", carry the highest ceilings: a search for an SEO company has a fraction of the volume of a search for attendance-management systems and a higher top bid per click. And one of the ten, an English-capable law firm, returned no data at all. The planner shows nothing below a volume threshold, which says something about the query, not about the demand. Yen figures are left in yen; rates move, and converting them here would date the article faster than the data does.
The three costs behind the media bill
Media spend is the visible number. Two others sit behind it. The first is management: someone has to build the campaigns, write Japanese ads, read the search-terms reports in Japanese and adjust, whether that is your team, a contractor or an agency. The second is the work the campaign lands on: a Japanese landing page, the form behind it, and measurement wired before the first click. A pilot that skips the second cost measures the wrong thing, because the traffic arrives on a page that cannot convert it.
Agencies charge for management in one of three ways: a percentage of media spend, a flat monthly fee, or hourly. Each is workable. What matters is that you know which one you are on, and whether the reports you receive show media cost gross or net of the fee. Ask both questions before signing. A clear answer is a good sign in itself.
In-house or an agency?
The decision is less about cost than about two capacities: someone who can research and write Japanese, and someone who reads the results and acts on them. If both exist in-house, run it in-house and keep the platform accounts, analytics and Search Console in your own name. If either is missing, an agency or contractor fills the gap, on the same condition: the accounts stay yours. The most expensive outcome in either setup is a pilot with no Japanese-capable reader of the search-terms report. That is why the order below puts measurement and one Japanese page before the pilot.
The order matters: what to do in the first 90 days
You can spend a first Japan budget in almost any order. Most of the expensive mistakes come from picking the wrong one: a rebuilt site before anyone checked what Japanese buyers search for, or thirty articles before a single page could convert. The sequence below is ordered so that each step makes the next one cheaper.
- Check Japanese demand first. Which queries exist for your category, in which script variants, with what intent, and what already ranks for them. This is days of work, not months, and it changes every decision after it. The four places this goes wrong are in Japanese keyword research: four assumptions that quietly break it.
- Build one Japanese page around what you found. Not a translation of your homepage: one page aimed at the highest-intent queries, carrying the company information and proof a Japanese buyer expects. Whether a full site build is warranted also falls out of step 1. That is Japanese website localization territory.
- Wire measurement before anything launches. Search Console, analytics, form events. If step 4 runs before this exists, its budget teaches you nothing.
- Run a small paid-search pilot. Paid is the cheapest fast test of Japanese messaging against real queries, and its search-terms data feeds the organic plan.
- Decide the content programme from data. Steps 1 and 4 tell you which topics deserve articles. Thirty articles first is the expensive version of guessing.
- Review the mix quarterly. Device split, channels, and what actually produced conversations. Market data like the chart above is the backdrop; your own analytics are the decision.
None of these steps requires a large retainer, and the first two are close to fixed-scope by nature. That is deliberate: the sequence exists so the cheapest learning happens first.
What does not transfer from your home market
- Keyword lists. Japanese queries are not translations of English ones. Script variants change intent, and some of your core terms have no meaningful Japanese equivalent at all.
- Proof. Logos and case studies that carry weight at home may mean nothing in Japan. Japanese B2B pages tend to carry explicit company information, terms and delivery detail. A page without them can read as incomplete to a buyer comparing vendors.
- Forms. Field expectations, required-field handling, confirmation steps and stated reply times differ, and this is repeatedly where localized sites lose the inquiry after everything else went right.
- The sales rhythm. Longer evaluations, more stakeholders, more weight on after-sales support, the ITA observation quoted above, with the caveat that this varies by industry and deal size far more than country-level advice admits.
Where the lines are
A marketing programme can build visibility, evidence and inquiries. It cannot register your company, hire your first employee, or answer your regulatory questions. For those, JETRO's Investing in Japan service is the public starting point, and the ITA guide linked above is worth reading in full for distribution and partnership strategy.
Our own lane is the layer in between: Japanese search demand, the pages built on it, the content and paid programmes that feed those pages, and the measurement that says whether any of it is working: Japan SEO services.
FAQ
Frequently asked questions
How much does it cost to advertise in Japan?
There is no platform minimum: Google Ads, LINE Ads and LINE Yahoo Ads all let you set the budget, by each platform's own pages (confirmed 2 September 2026). Per click, Google Keyword Planner showed top-of-page bids from about 250 to over 4,300 yen across ten Japanese B2B queries in our September 2026 check. The monthly figure depends on how many clicks you need to learn something, plus management and the Japanese page the clicks land on. Published minimums usually describe an agency's needs rather than yours. Start with a pilot you can read, then scale.
Is digital marketing in Japan different from other markets?
The tools are the same: Google, paid search, analytics. The inputs are not: queries, proof, form expectations and the weight of company information all change. In 2025 internet advertising crossed half of Japan's total ad spend for the first time, so a digital-first plan is the norm, not a shortcut.
Do we need a local agency or partner?
For distribution and sales, the ITA guide recommends local agents or distributors with industry relationships. For marketing execution, the requirement is narrower: someone who can research and write Japanese, and someone who reads the results. Where those sit, in-house, contractor or agency, matters less than whether both exist.
Does LINE work for B2B marketing?
LINE's reach is real: 100 million monthly users in Japan, by the operator's count. Its strength is retention and communication rather than B2B acquisition. Most B2B teams are better served starting with search, then revisiting LINE once there are customers to communicate with.
Is English content enough to start?
Some Japanese buyers read English, and English pages are fine for validating early interest. The comparison and decision content that wins inquiries is Japanese. When you want inquiries rather than signals, the priority pages need to exist in Japanese, built for Japanese queries. That is localization work, not translation.
How long until SEO produces results in Japan?
No one can promise a timeline, and we do not. Speed depends on the competition for your queries and the state of your site. The sequence above exists partly for this reason: a paid pilot produces learning in weeks while organic work compounds, and measurement tells you which is doing what.
If you want the demand check done for you
