Pop-ups & events in Shinjuku and Shibuya

About this site

Time-limited events in central Shinjuku and Shibuya — pop-up shops, IP collaborations, exhibitions, seasonal food events and release events. Built for visitors deciding what to do with an afternoon.

Where the listings come from

Listings are gathered and translated by AI rather than compiled by hand. Nothing is individually checked before it appears here, so every event links back to its original source — worth a look before you travel for anything.

Currently listing 209 events · last updated Aug 12.

What the confidence labels mean

  • No label— dates and venue were confirmed on the venue's own page.
  • Unconfirmed— the event was only found on a third-party listing, not on the venue's own site. It may be real, out of date, or wrong. Check the source before travelling.
  • No end date — the source did not say when it finishes.
  • End estimated — the page implied an end date without stating one. Treat it as a guess.

Why some events have no end date

Because the venue did not publish one. This site never guesses an end date, and never fills one in from “how long pop-ups usually run”. A confident wrong date is the most harmful thing an events site can print — it sends someone across Tokyo to a shop that closed last week. An honest blank is better.

Japanese names

Every event keeps its original Japanese title and venue string, and the venue line is never translated. Floor and space names like 新宿マルイ アネックス 6F are what appear on building signage and in Google Maps, so they are shown exactly as printed and can be copied with one tap.

Where an English title is uncertain, the Japanese title is shown instead — searching for a badly translated anime title finds nothing.

Images and where they come from

Most thumbnails are reduced-size copies of images published on the venue's own event page, shown alongside a link back to that page.

Where a picture came from somewhere other than the venue, it is always labelled with its source — on the card and again under the image on the event page. If an image carries no label, it came from the venue itself.

A labelled image may show a different branch or a different date of the same event, so treat it as an illustration rather than proof. Many events have no picture at all, which is deliberate: a coloured placeholder is honest, a photograph of the wrong shop is not. Stock photos, generic street scenes and AI-generated pictures are never used.

If you are a venue or rights holder and would like an image or listing removed, get in touch and it will be taken down.

Scope

Central Shinjuku and central Shibuya only — the walkable areas around each station. Permanent attractions, ordinary shop sales and regular restaurant menus are not listed; the test is whether the experience would exist if the event were not running.
