Geek Events in Budapest This Fall: Anime, Horror and K-Pop Take Centre Stage
Budapest’s autumn calendar has plenty to offer beyond exhibitions, sightseeing and evenings at the thermal baths. If your idea of a memorable city break involves cosplay, anime soundtracks, horror collectibles or spectacular K-pop choreography, October brings a particularly exciting weekend.
October 17 is the date to watch. MondoCon opens its two-day celebration of anime and pop culture at Hungexpo, HorrorCon brings Halloween thrills to the Lurdy Conference and Event Center, and K-Pop Dreamworld takes over the Riz Levente Sports and Events Centre. There is also an arena-sized K-pop production arriving on December 1—a winter bonus for anyone planning a later visit.
These events offer different ways to discover Budapest’s geek scene, whether you want to spend a whole weekend among fellow fans or add an afternoon of music and spectacle to your itinerary.
MondoCon: A Weekend of Anime, Gaming and Cosplay
Taking place on October 17–18, 2026, at the Hungexpo exhibition and convention centre, MondoCon brings together anime, manga, gaming, fantasy and cosplay fans for a weekend of shared obsessions. It is the kind of convention where the appeal lies as much in exploring as in following a fixed schedule: a striking costume might catch your attention on the way to a gaming activity, while music from another stage draws you towards your next discovery.
The programme spans cosplay contests, tabletop and board gaming, interactive activities, discussions, karaoke and music. For foreign visitors, the visual creativity and familiar fictional worlds provide an accessible starting point, even when individual discussions or activities involve Hungarian.
Saturday’s doors open at 9:30 am, and the convention concludes at 7 pm on Sunday. Treat that as a weekend event window rather than continuous overnight opening, and check the daily programme when deciding which activities you want to catch.
Best deals of Budapest
The previously advertised 9,000-forint discounted ticket offer ended on September 18, so it should not be treated as the current admission price when planning an October visit.
Who-ya Brings Anime Theme Songs to the MondoCon Stage
One of this autumn’s biggest MondoCon attractions is Who-ya’s concert, scheduled for Saturday, October 17, at 7 pm on the main stage. Fans of Jujutsu Kaisen will recognise “VIVID VICE,” while followers of Psycho-Pass will know songs including “Q-vism” and “Synthetic Sympathy.” Hearing the voice behind those tracks live adds a different dimension to music usually associated with an opening sequence or a favourite scene.
Who-ya is the vocalist at the centre of Who-ya Extended, whose music combines rock energy with the dramatic intensity of anime soundtracks. For fans, the concert is an opportunity to experience familiar songs beyond the screen; for newcomers, it offers a lively introduction to the musical side of anime culture.
A signing session is also planned during the convention, giving attendees another opportunity to connect with the performer. Check the event programme for the session’s timing and participation arrangements rather than assuming it immediately follows the concert.
The karaoke competition adds another musical thread to the weekend. This autumn’s rules require songs to be performed entirely in Japanese, with Beginner and Advanced categories planned if registration numbers allow, alongside a special Japan Embassy Award. Applications closed on September 6, so visitors arriving in October should view the competition as something to enjoy from the audience rather than an activity they can enter on the day.
HorrorCon: Budapest’s Halloween Gathering for Horror Fans
If your interests lean towards sinister creatures, unsettling film worlds and elaborate Halloween costumes, HorrorCon offers a very different atmosphere on Saturday, October 17. The event takes place at the Lurdy Conference and Event Center from 11 am to 7 pm, with themed exhibitions, costumed characters, interactive programmes and special guests.
The appeal extends beyond stage appearances. Horror installations and photo settings help turn the venue into an immersive gathering, while the marketplace provides a chance to browse dark-themed merchandise and collectibles. Come in costume if you enjoy becoming part of the spectacle, or simply arrive ready to appreciate the creativity around you.
For international visitors, the visual elements are a substantial part of the attraction. Some talks and guest appearances may be aimed primarily at Hungarian audiences, so it is worth distinguishing between programmes you want to follow closely and those you can enjoy through their atmosphere, costumes and displays.
The venue is at 12–14 Könyves Kálmán Boulevard in Budapest’s ninth district. Contrary to earlier announcements suggesting that ticket sales were still forthcoming, tickets are now available, with the venue advertising several admission categories. Visitors under 14 must be accompanied by a parent or guardian.
K-Pop Dreamworld: An Afternoon of Music and Choreography
Also taking place on October 17, K-Pop Dreamworld brings a concert-style production inspired by the music and choreography of BTS, BLACKPINK, TWICE, Stray Kids and Jennie. Expect performers interpreting the genre’s hits through live vocals, dance routines and theatrical staging—not appearances by the original groups.
There is a naming detail worth knowing when booking: the event is listed as K-POP Infinity Show, while its promotional description uses KPOP DREAMWORLD. These names refer to the same Budapest production at the Riz Levente Sports and Events Centre.
Doors open at 1:30 pm, with the performance beginning at 2:30 pm. Advertised ticket prices range from 11,990 to 15,990 forints, depending on category. The venue is at 86–88 Pesti Road in Budapest’s seventeenth district, outside the main sightseeing area, so allow time for the journey rather than treating it as a quick stop between central attractions. Parking nearby is limited, making an early arrival particularly useful for drivers.
This is an appealing choice if you want a focused afternoon event rather than a full convention day. It also gives newcomers a way into K-pop’s performance culture without requiring encyclopaedic knowledge of every group and release.
A Winter Bonus: K-POP Forever at Budapest Sports Arena
Although it falls outside the autumn season, K-POP Forever deserves a place on the radar of anyone visiting Budapest in early December. The production comes to the Papp László Budapest Sports Arena on Tuesday, December 1, 2026, at 7:30 pm.
This is another tribute-style spectacle rather than a concert by the original K-pop stars. Its appeal lies in the combination of performers, choreography and large-scale visual production, bringing the genre’s energy into an arena setting.
The ticketing page currently advertises admission from 15,078 forints, with the final cost depending on the ticket selected and applicable booking conditions. For travellers whose Budapest trip begins after the October convention weekend, it offers a separate opportunity to build an evening around Korean pop culture.
Planning Your Budapest Geek Weekend
The biggest practical consideration is the overlap: MondoCon, HorrorCon and K-Pop Dreamworld all have programmes on Saturday, October 17, and they take place at separate venues. Trying to experience everything in full would leave little room to enjoy any one event properly.
If Who-ya’s concert is your priority, build Saturday around MondoCon’s evening programme. If Halloween atmosphere is the main draw, make HorrorCon your daytime focus. K-Pop Dreamworld offers a more concentrated afternoon outing, while MondoCon’s second day on Sunday, October 18, gives you flexibility if you choose another event on Saturday.
Whichever route you take, this weekend offers a different perspective on Budapest: a city where fans gather not just to watch, but to dress up, sing along, share their interests and turn familiar fictional worlds into a real-life experience.
