San Japan 2026 Draws Record Crowd in San Antonio
The 17th annual San Japan convention, held over Labor Day weekend (August 29–31) at the Henry B. González Convention Center, exceeded organizer expectations with a record crowd. Attendees from across the country gathered for cosplay, gaming, and artist vendors, solidifying its status as a major regional hub for anime and gaming fans in Texas. The event's success underscores the growing popularity of anime conventions in the US South during late summer.

Fan Expo Canada Faces Overcrowding Petition
A petition has been launched by attendees of Fan Expo Canada, held recently in Toronto, demanding organizers stop overselling tickets. Fans reported severe difficulties moving through the Metro Toronto Convention Centre due to excessive crowding, with some describing the experience as unsafe. This incident highlights growing tensions between convention growth and venue capacity limits in North America.

Comic Treasure 48 Struggles with Low Attendance
In contrast to US growth, "Comic Treasure 48," a major doujinshi market held on September 6 at Intex Osaka, faced significant criticism for low attendee numbers. Images circulating on X (formerly Twitter) showed wide, empty aisles, prompting discussions about the regional disparity between Tokyo's Comiket and other Japanese markets. This trend raises questions about the sustainability of large-scale doujinshi events outside Tokyo.
Japan Expo 2026 Cosplay Highlights Released
Kotaku published a gallery of standout cosplay fits from Japan Expo 2026, which took place earlier this summer in Paris. The feature highlights high-quality costumes from Metal Gear Solid, Monster High, and Cyberpunk 2077, showcasing the enduring popularity of these franchises in European fandom. While the event itself is past, this content reflects the ongoing global reach of Japanese pop culture conventions.

Local view
Japanese media and community members are actively discussing the post-Comiket landscape. Following Comiket 108's conclusion in August, where 260,000 attendees were recorded, social media trends have shifted toward operational critiques. Participants have voiced concerns about staff authority and the logistical burden of cleanup, while recent coverage of Comic Treasure 48 highlights a perceived decline in regional convention vitality compared to Tokyo's dominance.
Context & numbers
- San Japan Attendance: The event drew a record crowd over Labor Day weekend, though exact figures were not immediately released in local reporting.
- Comiket 108 Baseline: For context, Comiket 108 held in August 2026 drew 260,000 attendees across two days, a decrease from previous years but still a massive scale compared to regional events like Comic Treasure.
On the radar
- New York Comic Con 2026: The 20th-anniversary show is scheduled for October 8–11 at the Javits Center. Early-bird ticket pricing ended on September 3, so standard pricing is now active.
- Anime San Diego: The inaugural Anime San Diego convention will take place September 5–6 at the San Diego Convention Center, filling the gap left after Comic-Con.
