Corrections Policy

This page sets out what Nijiiro does when an article contains a mistake. Our basic principles are that we don’t hide mistakes, and that readers can always see what we changed.

Our stance

Nijiiro deals in facts: systems, statistics and costs. We check primary sources wherever possible, but mistakes can still happen.

When they do, the worst thing we could do is quietly rewrite the article.

Unlike print, web articles can be changed after publication. That makes it easy to pretend a mistake never happened. If we did that, readers could no longer tell whether an article had been right from the start or had been fixed later.

So when we find a mistake, we leave a record of the correction on the article. It may not look perfect, but we believe it earns more trust.

Updates and corrections are different

An article’s content can change for two quite different reasons, and we treat them separately.

Type	What it means	What we do
Update	The article was correct when published, but a later change to a system, a fee revision or a change in circumstances has made it out of date.	We change the “Last updated” date and, where useful, note in the text what has changed.
Correction	The article was wrong when published: a factual error, a wrong number, a mixed-up source, or misleading wording.	We state the correction on the article. We never change it silently.

Three levels of correction

Minor errors

Typos, broken links and inconsistent spelling that don’t affect the meaning or a reader’s decisions are fixed without a note.

Corrections

Errors in numbers, how a system works, costs, facility information or sources that affect readers’ understanding are corrected with a note at the end of the article.

Serious corrections

Errors that change an article’s conclusion, could lead readers to make a wrong decision or complete a procedure wrongly, or involve inappropriate wording on a sensitive topic are also flagged at the top of the article.

Example: correction note at the end[Correction] (date) When first published, this article said the annual cap of the tuition support fund was X yen. The correct figure is Y yen. We apologise for the error.

Example: notice at the top[Important] Until (date), this article contained an error. Please see the end of the article for details of the correction.

Withdrawing an article

If the premise of a whole article turns out to be wrong, or keeping it online would harm readers, we unpublish it. Even then, we tell readers that we have done so and why.

Once a correction note has been published, we don’t delete it later. The history of corrections is itself a record of how the article has been handled.

How quickly we respond

Serious errors	As soon as possible once confirmed (as a rule, the same day)
Ordinary corrections	Within a few days of confirmation
Minor fixes	At our next regular review

In every case, we first check the facts against primary sources. If checking a report takes time, we will let you know.

If you find a mistake

If you spot an error or outdated information, we would be grateful if you let us know. These details help us check quickly:

the URL of the article
the part you believe is wrong
if possible, the correct information and its source

The editorial team checks every report. Sometimes we conclude that no correction is needed; in that case we will explain why.

If you run a facility or organisation we list: please contact us through the same form if details such as eligible grades, fees, how to apply or opening status are wrong or have changed. We will check and update them promptly.

If you shared your experience with us: if you would like it removed or changed, contact us at any time. We will make changes or remove it without asking for a reason.

We review this policy as needed. When we revise it, we update the “Last updated” date on this page.
