Tokyo Game Show 2026 will not get its fifth day. The Computer Entertainment Supplier's Association — CESA, the trade body behind the show — confirmed on Saturday that the whole of Monday, September 21 has been called off, with Typhoon No. 25, Dujuan, tracking towards the Kanto region. Sunday, September 20 still goes ahead. Monday does not happen at all.
Sunday is still on, with caveats
CESA's notice splits the remaining weekend in two. September 20 runs on its published schedule, 9:30 to 17:00, and because the day is proceeding as planned, there are no refunds for Sunday tickets. The organisers do leave themselves room: if conditions at the venue make it the safer call, individual facilities or pieces of content may be changed or dropped during the day. Anyone heading out to Makuhari on Sunday is being asked to check the latest forecast and the state of the trains before setting off, to allow extra time, and to expect rain and wind to strengthen as the day goes on.
Monday is cancelled outright
September 21 is a public holiday in Japan, and the show was due to run a shortened 9:30 to 16:00 to close out the week. That day is now gone entirely. CESA spells out its reasoning in the notice: as the typhoon closes in, wind and rain are expected to intensify from the afternoon onward, and the knock-on effect on public transport is the organisers' central worry. The decision was taken with the safety of attendees, exhibitors and staff in mind — and specifically with the question of whether tens of thousands of people could get home again safely once the weather turned. Cancelling a whole day of a sold-in trade show is a blunt instrument, but a venue in Chiba served almost entirely by rail does not leave many gentler options.
Monday tickets will be refunded
Tickets bought for September 21 are being refunded. CESA is directing holders back to whichever ticket agency they purchased through for the mechanics, since the process differs by vendor, and says it will post details on the official Tokyo Game Show site once they are finalised. Nothing changes for Sunday holders, who should treat their tickets as live.
Some of Monday's stages may still stream
Not everything scheduled for the final day is necessarily lost. CESA says it is working to put at least part of Monday's event stage lineup out as official online programming, provided the venue is safe enough to broadcast from. That is a genuinely open question rather than a plan: whether it happens, which segments make the cut, and what time they would go out are all still to be decided, and the organisers say they will announce on the official site and the show's social channels once they know. If you had a specific panel circled for Monday, that stream is the only remaining route to it.
A record-length show loses a day
The timing stings because this was meant to be the show's biggest year. TGS 2026 is the 30th edition, and CESA stretched it to five days — September 17 through 21, two business days followed by three open to the public — the longest run in the event's history. The exhibitor numbers matched the ambition. When the doors opened on Thursday, CESA counted 1,138 exhibiting companies and organisations, 540 domestic and 598 from overseas, drawn from a record 53 countries and regions and filling 3,999 booths across halls 1 to 11 at Makuhari Messe, the International Conference Hall and the TKP Tokyo Bay Makuhari Hall. That beat last year's record exhibitor count. The organisers had been planning for 300,000 visitors across the run.
Losing Monday removes a third of the public days from that plan. It also removes the quietest-on-paper day of the three, the holiday Monday that was the whole justification for the five-day format in the first place. The show still got its business days, its opening weekend and the bulk of its announcements out the door before the weather intervened, which is more than can be said for some events that have run into typhoons in late September.
What the forecast looks like
The Japan Meteorological Agency has Dujuan approaching Kanto on Monday, bringing heavy rain, strong winds and high waves before it moves off and weakens. The Tokyo Bay coastline, which is precisely where Makuhari sits, is among the areas flagged for the strongest gusts. That is the window CESA has cleared its schedule around: Sunday is expected to be wet and windy but workable, Monday is expected to be neither.
If you were going on Monday
Three practical things. Start the refund through the agency you bought from rather than through CESA directly. Watch the official Tokyo Game Show site and its social accounts for the streaming decision, which is the only part of Monday that could still materialise. And if you are attending on Sunday instead, treat the organisers' advice as the floor rather than the ceiling — check your line before you leave, and plan to be out of Makuhari well before the evening. CESA has said further updates may follow if the typhoon's track or the rail situation changes again, so the notice posted on Saturday is unlikely to be the last word.
