GM, COT❣️ Yuzunoko here.
Do you assume that once you've paid a cosplay event's "registration fee," the changing room and a place for your bags all come with it?
When I lined up the official participation guides for some of the big events, what the registration fee or pass actually includes turned out to be pretty different from event to event.
Some include the changing room, some charge extra for the cloakroom, and some need a separate entry ticket on top of everything.
The ones I compared are acosta! in Ikebukuro (a cosplay event; Ikebukuro is a district in Tokyo), the Ikebukuro Halloween Cosplay Fest (Ikeharo for short), Nipponbashi Street Festa (Stofes for short) in Osaka, Tokyo Game Show in Makuhari (a convention area in Chiba, next to Tokyo), and Comic Market.
All the numbers come from the official pages for the 2026 editions, and they may change next time.
Events where one participation ticket gets you into the changing room
The simplest setup is one participation ticket that lets you use the changing room, with a baggage area at the venue too.
On the event page for acosta! at Ikebukuro's Sunshine City (a big shopping complex), on November 7 and 8, the Regular ticket is 2,380 yen in advance (2,900 yen on the day), and the Early ticket, which gets you in earlier, is 2,980 yen in advance (3,500 yen on the day). Both let you take part as a "cosplay changing room" user, a "photographer," or a "general" visitor.
The Ikebukuro terms of participation explain how the baggage area works: you get one bag tag per item, and you pick it up by matching it with your stub.
Whether the baggage area costs extra wasn't written on any of the pages I read.
Ikeharo 2026 works the same way. Its ticket page says, "You can use the changing rooms and the baggage area."
The General cosplay ticket is 2,980 yen/day in advance, and the Premium ticket, with earlier check-in, is 3,980 yen/day in advance.
For Stofes 2026, held on May 17, 2026, the guide listed two kinds of changing rooms: a "general changing room" with no limit on numbers, and a "capacity-limited changing room."
The sales page says each changing room has a free cloakroom and restrooms.
On the official shop, the common wristband for cosplay and camera participation was shown at 3,300 yen, and web orders had a separate 500-yen shipping fee.
Events where you need an entry ticket on top of the registration fee
If you're cosplaying at a trade show or a doujinshi market, the ticket to get in and the cosplay registration are separate.
On the Tokyo Game Show 2026 cosplay area page, the registration fee is "including changing room / cloakroom fees," at 2,000 yen regular and 3,000 yen early morning (tax included).
On top of that, it says you need a 1-day entry ticket to register for cosplay.
The early-morning slot is apparently for people who want to enter the venue already in costume, with check-in starting from the first train of the day (lining up from the first train takes some serious commitment).
At Comiket, cosplay registration is 500 yen a day, and registering lets you use the changing rooms. The C108 (the 108th Comiket) support page says this is needed separately from your entry ticket or wristband.
The cloakroom is a paid service run by the venue, at 500 yen per item. If any side (length, width or height) is over 120 cm, there's a 300-yen surcharge.
So going by the registration fee alone it's the cheapest, but checking a bag costs extra.
Side by side, what's different?
Here's what the official pages say, lined up by what's included.
- acosta! Ikebukuro: changing room with the participation ticket, baggage area available (no mention of a fee)
- Ikeharo: changing room and baggage area both included in the participation ticket
- Stofes: general changing room with the pass, cloakroom at each changing room stated as free
- Tokyo Game Show: changing room and cloakroom included in the registration fee, entry ticket separate
- Comiket: changing room with the registration fee, cloakroom extra at 500 yen per item, entry ticket also separate
Adding whether you need an entry ticket, here it is as a table.
Leaving Comiket aside, what a cosplayer pays came to roughly the 2,000s to 3,000s of yen, going by the official pages' numbers for the basic advance tickets.
Some on-the-day tickets and tickets with a choice of changing room cost more than that. And for events where the entry ticket is separate, you need to add that on too.
Even within one event, your choice of changing room changes the price
Even within a single event, there are sometimes tickets at different prices depending on the kind of changing room.
At Stofes 2026, the "pass with capacity-limited changing room" was 4,800 yen, positioned as a step-up changing room with a cap on how many people use it.
It says it's only sold as a set with the pass, only in person at the stores that run the changing rooms, and you can't use a capacity-limited changing room at any store other than the one you bought from.
Ikeharo 2026 also has a ticket that lets you use the changing room and lockers at Cosset's Ikebukuro main store, at 6,400 yen/day in advance for October 31 and November 1.
With Ikeharo's Premium 3DAYS ticket, you also get the perk of leaving your bags overnight between days.
If you care about how roomy or crowded the changing room is, a ticket like that is one option (a changing room where you can take your time sounds kind of dreamy❣️)
On the flip side, some events have sold tickets for taking part without a changing room. Hokocos in Nagoya (a cosplay event on a pedestrian-only street) sold a "cosplay participation ticket (no changing room)" and a "cosplay changing room ticket (includes participation)" separately at its May 2024 event.
Its official site says there's no event planned for spring 2025, and autumn onward is undecided.
What you can't check, and what you keep with you
One thing that came up again and again across the events I compared: valuables are your own responsibility.
Tokyo Game Show says to always carry valuables and fragile items yourself, and the Stofes terms also ask you not to leave valuables in the baggage area.
Ikeharo's participation rules even include a list of things you can't leave, like cash, cards, fragile items and anything that smells.
The other thing they share is a ban on arriving and going home in costume. acosta!, Ikeharo, Tokyo Game Show and Comiket all say so in their official rules.
Ikeharo bans changing at home or at a hotel and then coming to the event, except for a special Prince Hotel stay plan. Stofes also bans changing and doing makeup anywhere other than the designated changing rooms, like station or public restrooms.
