Why opening hours online are often wrong in Japan, and how to check them

You looked up a temple on a map app. It said "Open". You arrived at 16:40 and the gate was shut. Nobody lied to you. The hours you saw were a simplified copy of a page that had more rules on it.

This article explains where that gap comes from, and a short routine to check hours before you go. It is also the reason this site exists, so we will be clear about what we do and do not know.

Where the hours you see online come from

The hours on a map app, a travel blog or a booking site are copies. They come from a mix of:

• The business or site itself, if it manages its own listing. On Google, owners set regular hours and can add "special hours" for short changes. Google's help page says special hours are for when a business "temporarily adjusts its hours of operation or remains closed for up to 6 days in a row."
• Other users. On Google Maps, anyone can add a missing place: "The place shows publicly once it's added."
• Writers, who copy the hours on the day they visit and may not update the post later.

None of these is wrong on purpose. The problem is that the copy is shorter than the original.

What gets lost in the copy

Official pages for sights in Japan often describe hours as a set of rules. A single line of hours cannot hold them.

Seasons. Kenrokuen in Kanazawa opens at 7:00 from March 1 to October 15, and at 8:00 from October 16 to the end of February. A single line of hours can only show one of these.

Last entry. The Kyoto Imperial Palace lists an entry window and a separate "must leave by" time. From October to February, entry is 9:00-15:20 and visitors must leave by 16:00. A listing that says "9:00-16:00" is not wrong, but you cannot walk in at 15:45.

Holiday rules. The Tokyo National Museum is closed on Mondays, but when Monday is a holiday it opens and closes on the next weekday instead. A listing that says "Closed Mondays" will be wrong on those weeks.

Closures longer than a few days. In the examples we checked, New Year closures run from two days (Himeji Castle) to eight days (Kyoto Imperial Palace). Closures like these do not always fit the short-term "special hours" tool described above, so whether they show up depends on how the listing is maintained.

We explain these patterns in more detail, with more examples, in Opening-hours traps in Japan.

What we have not measured

We have not measured how often map apps or blogs are wrong for sights in Japan. We only know the rules are there on the official pages. Among the 1,081 opening-hours entries we have published, at least 380 mention a season or a month range, and at least 348 mention a last-entry time. (Counted by text search on 2026-09-29. Entries with other wording are not included.) Every one of those is a place where a one-line summary can go wrong.

A two-minute check before you go

1. Find the official page. Search for the Japanese name plus 公式 ("official"), or start from the city or prefecture tourism site. Many official pages have an English version; if not, a browser translation is enough for times and dates.
2. Read the hours for your date. Look for a season or month range, and read the one your trip falls in.
3. Find the last-entry time. It may be written as 最終入場, 入場は〜まで or 受付終了.
4. Check closed days, then the exceptions. Look for 休館日 or 定休日, then check what happens when a holiday falls on that day, and whether there is a New Year closure.
5. Look for a news or notice section. Temporary closures are often posted there, not in the hours table.

If you do this once for each place you cannot miss, you avoid most of the traps.

How Verified in Japan handles this

• Every fact on a spot page comes from the official page of the place or a local-government tourism page, and shows the date we checked it.
• If the official page does not say something, we write Not checked yet. We do not fill the gap from a review site or a map app.
• We re-check on a schedule, and sooner when a traveler reports a change.

We can still be out of date. That is why we show the check date and link to the source, so you can see what we saw.
