Ultra Japan has published a list of things not to do at its 2026 edition, and one of them should not have needed saying. In an Instagram post this week, the festival asked attendees to avoid behaviour causing inconvenience to neighbours or other visitors. Littering, drunken disturbances and loud music near the venue are on the list, which is standard. Printed in bold yellow for emphasis is a ban on defecating anywhere other than a toilet, which is not.
Rules of this kind tend to be written after the fact rather than before it. EDM.com makes the obvious inference, and the post itself carries a warning that Ultra Japan may not be able to be held in future if such behaviour happens, which places the festival's continued existence in the same sentence as basic bathroom etiquette.
A few hours earlier the organisers had posted separately about mosh pits, banning them outright and warning that anyone breaking the rule may be removed from the festival grounds without a refund. That is a firmer sanction than the conduct list carries, and it suggests the two posts came from different concerns rather than one sweep.
The weather is the other thing hanging over the weekend. Organisers are monitoring Typhoon No. 25, forecast to approach the Kanto region over the same two days, which is a more immediate threat to the event than anything in the conduct list.
The festival runs on 19 and 20 September at Odaiba Ultra Park in Tokyo, with sets from Alesso, Peggy Gou and Sara Landry among others. Knock2, who released his first new original music in more than a year this week, is also on the bill.
Our earlier note recorded that no reason for the new rules had been reported, which remains true in the narrow sense: EDM.com names no specific incident at a past edition. The post's own warning about the festival's future is the closest thing to an explanation anyone has offered. Festival dates and lineups are tracked on the festival tracker, and the rest of our coverage of the scene is on the electronic hub.
