Many 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 much of your Japanese audience is away from their desks. Publishing into those windows is not fatal, but it often 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 April 1 to March 31. Most large companies, and the government, use it. Much of the business calendar follows from it.
- Budgets are set for the year from April. A B2B proposal arriving in April often meets a budget holder with money and a mandate. The same proposal in February may meet someone who has already spent it.
- Staff move in April. New graduates join in a single intake on April 1, and internal transfers often 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 largely consumed by closing the books. Decisions that are not already in motion tend to 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. In our experience, 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 backward. If you want to be visible for the April cycle, the content should exist by January.
The three windows when most people are away
Japan tends to concentrate its time off into three periods rather than spreading it across the year. During each, B2B activity does not just slow down — it largely stops.
| Period | Roughly when | What actually happens |
|---|---|---|
| New Year | Dec 29 – Jan 3 | The deepest shutdown of the year. Most offices close, and 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 inquiries tend to 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, in our experience, effective: we do not launch anything into these windows. A page published the day before Golden Week spends its first two weeks with a small audience, and that may be when early engagement signals form. 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 much of that demand is searched for weeks in advance, not during. Golden Week travel research mostly happens in March and early April.
The approval process is often 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 may never 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 often 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. Probably 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. A good window for content that supports a case being built. |
| Dec | Publish in the first half of the month or not at all. Little 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. We think publishing steadily helps a site stay 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 usually 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 in the data we have seen, it is one of the clearer seasonal patterns in Japanese B2B. Informational queries tend to be much flatter. If you are checking your own data, separate the two before drawing a conclusion.

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 B2B vs. B2C SEO in Japan, and the wider sequence is in our Japan SEO guide. More about how we work.
