Foreign teams plan Japanese content on the calendar they already use. Campaigns land in January, budgets reset with the new year, and the summer is treated as a quiet stretch to be worked through.
Japan runs on a different clock. The business year starts in April, the buying cycle is built around it, and there are three windows each year when your Japanese audience is genuinely not at their desk. Publishing into those windows is not fatal, but it wastes the launch.
Here is the calendar we plan Japanese production against, and what each period does to demand.
The year starts in April
The Japanese fiscal year runs 1 April to 31 March. Most companies, and the government, use it. Almost everything downstream follows.
- Budgets are set for the year from April. A B2B proposal arriving in April meets a budget holder with money and a mandate. The same proposal in February meets someone who has already spent it.
- Staff move in April. New graduates join in a single intake on 1 April, and internal transfers happen at the same time. Your buyer in March may not be your buyer in April.
- March is closing, not buying. The final weeks of the fiscal year are consumed by closing the books. Decisions that are not already in motion get pushed to the new year.
The practical consequence for content is straightforward. Anything aimed at a purchase decision — comparison pages, pricing explanations, implementation guides — should be indexed and ranking before April, not published in April. Search demand for evaluation queries rises as budgets open, and a page published that month is still being crawled while the decision is being made.
Work backwards. If you want to be visible for the April cycle, the content needs to exist by January.
The three windows when nobody is there
Japan concentrates its time off into three periods rather than spreading it across the year. During each, B2B activity does not slow down — it stops.
| Period | Roughly when | What actually happens |
|---|---|---|
| New Year | 29 Dec – 3 Jan | The deepest shutdown of the year. Offices close. Email goes unanswered. Consumer search shifts to food, travel and family. |
| Golden Week | Late April – early May | A cluster of public holidays; many companies bridge the gaps into a continuous break. B2B enquiries fall away and resume the following week. |
| Obon | Mid-August | Not a public holiday, but widely taken as leave. Travel peaks. Much of B2B is operating on a skeleton staff. |
What we do about it is unexciting and effective: we do not launch anything into these windows. A page published the day before Golden Week gets its first fortnight of life with no audience, which is exactly the period when early engagement signals are being formed. We publish before, or we publish after.
The reverse is true for consumer categories. These windows are peak demand for travel, food, gifts and entertainment — but that demand is searched for weeks in advance, not during. Golden Week travel research happens in March and early April.
The approval process is slower than the sales cycle you know
Japanese companies typically approve purchases through a documented circulation process, in which a proposal moves through each stakeholder in turn and collects approvals on the way. It is thorough, it is written down, and it takes time.
Two things follow for content, and they are the reason this matters here rather than in a sales playbook.
- Your pages get read by people you never speak to. The person who found you is assembling a case for colleagues who will not visit your site. Anything they cannot copy into an internal document — a claim without a source, a price with no basis, a comparison with no method — weakens the case at a stage you cannot see.
- The lead time is long enough to cross the fiscal boundary. A process starting in January may not conclude until the new budget year. Content that helps someone wait — implementation timelines, what a rollout involves — does real work in that gap.
A publishing calendar that fits the year
| Period | What to publish |
|---|---|
| Jan – Feb | Evaluation and comparison content, so it is indexed and ranking before budgets open in April. The highest-leverage window of the year for B2B. |
| Mar | Nothing that needs an immediate response. Publish foundational and reference material; the audience is closing its books. |
| Apr | Onboarding, getting-started and implementation content. New people in new roles are searching to orient themselves. |
| May – Jul | The longest uninterrupted working stretch. Do the heavy production here. |
| Aug | Publish before Obon or after. Use the quiet period for technical work and rewrites rather than launches. |
| Sep – Nov | Second-half budget reviews and planning for the next year begin. Good window for content that supports a case being built. |
| Dec | Publish in the first half of the month or not at all. Nothing lands after the 25th. |
None of this changes what you write. It changes when the work you have already paid for gets a chance to be seen.
Common questions
Does this apply if we sell to Japanese consumers rather than businesses?
The holiday windows apply, but inverted — they are peak demand rather than absence. The fiscal-year effect largely does not, with the exception of categories tied to the school and hiring year, such as education, recruitment and anything bought for a new household in spring.
Should we stop publishing during the quiet periods?
No. Stop launching. Publishing steadily is how a site stays credible to a crawler. Keep the cadence and move the pieces you care about to either side of the window.
Our head office wants a global campaign date. What do we tell them?
That Japan can hit the same date, and that the Japanese content should exist and be indexed before it. The launch is a moment; search visibility is built weeks earlier. These are not in conflict unless the content is written the week of.
Is the April effect visible in search data?
In commercial and evaluation queries, yes, and it is one of the clearer seasonal patterns in Japanese B2B. Informational queries are much flatter. If you are checking your own data, separate the two before drawing a conclusion.
Working on Japan?
Nihongo Search is published by Amanaut, Inc., a small Japanese SEO and content company in Tokyo working with companies entering the Japanese market, and this is the calendar we schedule production against. How the audience splits before any of this applies is in BtoB vs BtoC SEO in Japan, and the wider sequence is in our Japan SEO guide. More about how we work.
