HYPER JAPAN Festival at Olympia: Tickets, Dates, Cosplay Rules and Getting There

HYPER JAPAN calls itself the UK’s biggest Japanese culture event, and for three days a year it takes over Olympia’s Grand Hall with a food market, a stage running idol pop to taiko drumming, and enough cosplay to make the District line home worth timing carefully. The 2026 festival ran Friday 24 to Sunday 26 July; 2027 dates haven’t been announced.

💡 The Short Version: A single day starts at £28.35 for Friday, rising to £41.55 for Saturday and £31.50 for Sunday, all including booking fees. A 3 Day Pass covering the whole run is £78.75. Friday — the shortest day and the cheapest ticket — is the quietest session; Saturday carries the Cosplay Masquerade, most of the headline music and the highest price. Cosplay is welcome, but metal blades, gun-shaped props and anything over 1.5m wide are banned outright. The nearest station is Kensington (Olympia), on the Overground’s Mildmay line every day; the District line’s direct shuttle from Earl’s Court only runs at weekends.

Tickets: what each one gets you

Every ticket is for a specific day and time slot — HYPER JAPAN doesn’t sell a walk-up single “session” ticket beyond that. Prices below are the 2026 festival’s, including Gigantic’s booking fee.

Workshops and meet-and-greets sit on top of a day ticket rather than replacing one: the Awaodori dance workshop ran £17.81 and Japanese mask-making £38.16 in 2026, each bookable only alongside an entry ticket for the same date, and the smaller sessions (mask-making in particular) sold out days ahead. A day ticket also does not include re-entry by default — leave the hall and you queue again at the main entrance, wristband in hand.

Which day to pick

Friday is the one to book if you want space to look at the market properly. It’s the only weekday of the three, it runs just eight hours against Saturday’s ten, and HYPER JAPAN prices it a third cheaper than Saturday — a fair signal of where the organiser expects the smaller crowd. Friday’s stage still runs a full programme (rock band The Sixth Lie, taiko soloist Takuya Taniguchi and singer-songwriter UPIKO among 2026’s line-up), just without the Saturday-only Cosplay Masquerade or the acts scheduled for the busiest slots.

Saturday is the one to avoid if you dislike queuing. It’s the longest day, it’s priced highest, and it carries the Cosplay Masquerade, the headline anisong sets and the day most families attend. HYPER JAPAN’s own advice for busy periods is to arrive early for anything you don’t want to miss, since popular shows can hit capacity and hold visitors at the door until space frees up.

What’s inside: the market

The market runs food, drink and craft stalls rather than one themed “street” — HYPER JAPAN dropped its dedicated Sake Experience area for 2026, but sake was still poured everywhere: KANPAI, the UK’s first sake brewery, alongside umeshu and sake specifically imported from four producers in Wakayama Prefecture, plus Suntory Toki whisky and Ozeki and MIO sparkling sake on the drinks side. On the food side, Dragonfly Foods brought UK-handmade organic tofu, Kewpie its mayonnaise, and Japan Centre — the Panton Street shop that’s also the best walk-in Japanese food counter in the West End, covered in our Japanese restaurants guide — ran its own stall alongside importers like Taste of Japan and Unisnacks.

Bring cash as a backup. HYPER JAPAN says it’s working towards a cashless event, but there are no cash machines inside the venue and some traders still only take cash.

Cosplay: what’s allowed and what isn’t

Cosplay is actively encouraged — there’s a dedicated Cosplay Masquerade on the Saturday stage — but the rules are specific and checked at the door:

• No metal blades of any kind, sharp or blunt: swords, axes, kunai, or costume weapons with metal parts.
• No gun-shaped props, regardless of what they’re made from, including airsoft and BB guns.
• No bokken, nunchucks or knuckledusters, and no hard bats, clubs or golf clubs.
• No laser pointers, drones, vuvuzelas or silly string.
• Nothing over 1.5m wide or 2m tall — large wings, banners and puppets included.
• No flame, smoke, or exposed electrical arcs built into a costume or prop.
• No fetish wear or nudity as general attire.

Staff can search bags and props on entry, and the organiser reserves the right to turn away anything that doesn’t meet the rules on the day — better to check a specific prop against the list before building a costume around it.

The stage: what it actually sounds like

HYPER JAPAN’s stage moves between genres inside a single hour rather than sticking to one: 2026 ran J-rock bands (The Sixth Lie, QUEEN BEE, Re:O), anisong vocalists (Eir Aoi, known for theme songs across the anime charts), idol acts (UPIKO, Sacred Fleramo), a viral dance troupe (avantgardey), and traditional performance sitting right alongside it — Gagaku court music, Awa Odori festival dance, a Shorinji Kempo martial arts demonstration and taiko soloist Takuya Taniguchi. Sunday closed with the Hyper Fashion Show, and Sunday afternoon also carried a voice actor conversation with Chiaki Kobayashi (Frieren, Hell’s Paradise). None of it needs an add-on ticket — the stage programme is included in day entry, only the smaller hands-on workshops cost extra.

Getting to Olympia

Kensington (Olympia) station sits at the venue’s own entrance, on Olympia Way — a different station from High Street Kensington, a 15-minute walk away, so check which one a map app is sending you to.

⚠️ The District line doesn’t reliably reach Olympia on a Friday. Its shuttle from Earl’s Court is a weekend-and-public-holiday service — for the Friday session, plan on the Overground from the start rather than assuming the Tube map’s direct line will be running.

• London Overground’s Mildmay line runs every day HYPER JAPAN is open, roughly every 15 minutes off-peak, one way to Clapham Junction and the other via Willesden Junction to Stratford.
• Southern services call roughly hourly, to East Croydon and Watford Junction.
• The District line only runs a direct shuttle to Kensington (Olympia) from Earl’s Court at weekends and on public holidays, plus occasionally when Olympia has an event on — so it’s likely to run across the Saturday and Sunday sessions, but check TfL before relying on it for the Friday session, since a weekday shuttle isn’t guaranteed. On a weekday, change at West Brompton from the District line onto the Overground instead.
• Parking has to be pre-booked through the venue, ideally more than 24 hours ahead, with cost depending on length of stay.

Olympia is step-free, with lifts to the accessible entrance, which shares the main entrance rather than a separate route.

Where to stay

For the shortest walk, Hyatt Regency London Olympiaad sits inside the redeveloped Olympia site itself, about a minute from the station, at roughly £220 a night. For less money, Premier Inn London Kensington (Olympia)ad on West Cromwell Road has air conditioning in every room and is a short walk from Earl’s Court station. Our where to stay in Kensington guide covers both in full, along with cheaper options in Earl’s Court, and our Kensington area guide covers the neighbourhood itself — Holland Park’s Kyoto Garden is a genuinely fitting stop either side of the festival.

Other anime and J-culture events in London

HYPER JAPAN isn’t the only date worth knowing if this is your calendar:

• AnimeCon London, 3–4 October 2026, also at Olympia, from £25 — a two-day anime and manga convention with a Cosplay Catwalk, Artist Alley and voice actor guests including Justin Briner and Jason Liebrecht.
• MCM Comic Con London, 23–25 October 2026 at ExCeL — the UK’s biggest pop culture convention, wider than anime alone, spanning comics, gaming and film and TV guests.

Our exhibitions and conventions calendar tracks these and the rest of London’s convention year in one place. Olympia’s Grand Hall doesn’t stand empty between them, either — The Ideal Home Show takes over the same halls 2–11 April 2027, which is worth knowing since it’s the same station and the same nearby hotels covered on this page.

2027 dates and a winter edition

HYPER JAPAN hadn’t announced 2027 dates as of late September 2026. The 2026 festival ran Friday 24 to Sunday 26 July, and exhibitor registration for that show had opened by late January 2026 — so a 2027 announcement is more likely to land over the winter than close to next summer. There’s no HYPER JAPAN Christmas market or winter edition planned in London this year: Olympia’s own festive events this winter, the Spirit of Christmas Fair and the Ideal Christmas Show, run independently of HYPER JAPAN.
