Texas hosts two of the biggest anime conventions in the South, and if you follow the scene at all, the question comes up every year: San Japan or Anime Matsuri? Both draw tens of thousands of fans, both pull real industry guests, and both deliver a vendor hall worth burning a credit card in. The differences come down to scale, culture, scheduling, and how you want to spend your con weekend. Here is how they actually stack up.
Scale and Attendance Compared
San Japan runs every August at the Henry B. González Convention Center in downtown San Antonio, pulling around 30,000 to 35,000 attendees across its three-day run. The convention occupies multiple halls in the Henry B., with programming spread across dedicated rooms for panels, gaming, and the main events ballroom. It has grown steadily since its founding in 2008 and sits firmly in the upper tier of Texas anime cons.
Anime Matsuri operates on a different level. The Houston convention, held each March or April at the George R. Brown Convention Center, regularly claims attendance figures north of 50,000 and has in strong years pushed toward 60,000. The George R. Brown gives Anime Matsuri room to sprawl — the vendor hall alone rivals the footprint of some smaller cons. If raw headcount and square footage matter to you, Anime Matsuri wins that comparison without argument.
That size difference shapes the entire experience. San Japan feels more contained and navigable, while Anime Matsuri can feel overwhelming on peak days. Lines at Anime Matsuri for popular guests and major panels stretch long; San Japan lines move faster because the crowd cap is lower.

Guest Lineup and Industry Access
Anime Matsuri has historically been the Texas con that Japanese studios and major voice actors put on their North American tour schedule. Past years have brought guests from major productions including talent connected to franchises like Naruto, Attack on Titan, and Dragon Ball. The convention has had Japanese animation directors, composers, and voice actors appear in person — a level of access that few U.S. regional cons can match. The trade-off is that Anime Matsuri has faced documented criticism over guest treatment in prior years, and that reputation has colored how some fans view the event. The organizers have publicly addressed these concerns, and the convention continues to operate, but the history is worth knowing before you book.
San Japan leans into the North American voice acting community and builds strong relationships with ADR studios in Texas. Funimation talent — now under Crunchyroll — has appeared regularly, and the con cultivates returning guests who genuinely engage with the fan community rather than doing pure autograph-table appearances. Industry panels at San Japan tend to feel conversational rather than scripted. If your priority is deep interaction with dub voice actors and honest Q&A sessions, San Japan delivers that more reliably.
Both cons offer VIP and photo-op packages with premium guests. Anime Matsuri pricing for top-tier Japanese guests runs higher, reflecting the travel costs involved. San Japan packages are generally more accessible without sacrificing meaningful access.

Vendor and Artist Alley Experience
The Anime Matsuri vendor hall at the George R. Brown Convention Center is massive. Japanese import dealers, large domestic retailers like Right Stuf (now folded into Crunchyroll’s physical arm), and specialty cosplay supply vendors fill the floor alongside a sprawling artist alley. If you are hunting specific figures, limited releases, or out-of-print manga volumes, Anime Matsuri’s vendor room gives you the best shot at finding them in Texas. Budget time — navigating the entire floor in one pass takes the better part of an hour.
San Japan’s artist alley at the Henry B. González Convention Center punches above its weight for a con its size. Local Texas artists dominate the alley, and the community-first culture means you find more original work and less mass-produced fan art compared to larger cons. Commissioners report faster turnaround conversations and better artist availability at San Japan’s alley versus Anime Matsuri, where the busiest tables stay mobbed all weekend. If supporting independent Texas creators is your priority, San Japan’s alley is the right room.
Both cons have strong tabletop and gaming sections. San Japan integrates a dedicated gaming room where attendees run tournaments in fighting games, card games, and JRPGs. Anime Matsuri hosts a larger gaming floor but the FGC presence at San Japan is tighter and more organized, with bracket play running cleanly through the weekend.
Convention Venue and City Experience
San Japan’s location in downtown San Antonio is one of its genuine advantages. The Henry B. González Convention Center sits a short walk from the River Walk, which means your off-hours have a built-in destination. Cosplay groups flood the River Walk each August weekend, and restaurants and bars along the water are used to the crowd. Hotel options within walking distance include the Grand Hyatt San Antonio and the Marriott Rivercenter, both connected directly to the convention center via walkways. San Antonio in August is hot — triple digits are common — so factor that into any outdoor photo shoots.
Anime Matsuri’s home at the George R. Brown Convention Center places it in downtown Houston near Discovery Green and within reach of the Houston Theater District. The convention uses the full GRB footprint plus the adjacent Hilton Americas, which serves as the primary overflow hotel and hosts its own programming tracks. Houston’s light rail system, specifically the METROrail Red Line, connects the GRB to other parts of the city, which helps if you want to explore Midtown or Montrose between con events. March and April weather in Houston is more comfortable than August in San Antonio, which is a practical consideration for elaborate cosplay builds. Read the Anime Matsuri Houston Cosplay Props and Logistics Guide for venue-specific prep tips.
San Antonio has the River Walk atmosphere and the cultural density of a city built around tourism, which makes con weekend feel like a full event even outside the convention floor. Houston offers more urban sprawl and a broader range of food and nightlife options, but requires more intentional navigation. Neither city is a bad choice — they just offer different con-adjacent experiences.
Which Anime Con Is Right for You
If you are a cosplayer competing at the craftsmanship level, San Japan’s Masquerade is one of the better-run competitions in Texas. The judging is thorough, categories are well-defined, and the community treats the Masquerade as a genuine event rather than an afterthought. EVA foam builders and seamstresses who want their work evaluated seriously should put San Japan on their calendar.
If your goal is proximity to Japanese industry talent — directors, composers, seiyuu from major current productions — Anime Matsuri is where you need to be. No other Texas con consistently brings that tier of international guests. Go in with clear expectations about the scale and the line management, and the guest access is worth it.
If you want both, you can attend both in the same calendar year without any conflict. Anime Matsuri runs in March or April, San Japan runs in August. Four months of separation gives you time to recover your budget and your feet. Texas fans who are serious about the convention circuit treat both as essential rather than competing events.
For a weekend with a tighter budget and a more community-driven vibe, San Japan is the easier recommendation. For maximum scale, the widest vendor selection, and the deepest Japanese industry access, Anime Matsuri earns its place as the bigger show. The right answer depends entirely on what you want to bring home from the weekend.

Which Texas anime con has better cosplay events?

Is Anime Matsuri good for industry guests and voice actors?
Anime Matsuri has historically brought the highest tier of Japanese industry guests of any Texas convention, including animation directors, composers, and Japanese voice actors from major active franchises.
