About San Japan

San Japan 2025

The Convention

Formed in fall 2005, San Japan, LLC is a fan-run organization that hosts an annual anime- and gaming-focused convention. We provide high-quality entertainment and education while fostering a safe, fun environment for all our attendees. We strive to cultivate an acceptance and appreciation of anime, gaming and related fandoms in South Texas.

Our Mission

San Japan strives to provide an opportunity for all participating cultures. For participants to come together in appreciation of Japanese animation and other unique aspects from surrounding Asian and Fan Cultures.

Our History

San Japan was started in late 2005 by a group of volunteers. They worked together to bring a different type of Japanese fan and animation convention to San Antonio, Texas.

A one-day event called San Japan: Zero Day Anime was held at Our Lady of the Lake University to give attendees a taste of what to expect from the main convention. Over 800 people attended this event.

The inaugural three-day convention was held in San Antonio, Texas, on August 8-10, 2008. It was a success, with over 3500 attendees at the convention. Afterward, planning began immediately for the second year, called San Japan 2. In the following years, San Japan continued to grow, reaching nearly 7000 attendees by 2011.

In 2012, San Japan moved to the Henry B. Gonzalez Convention Center and the San Antonio Grand Hyatt Hotel, the largest hotel and convention center within the city limits of San Antonio. The Henry B. Gonzalez Convention Center will be San Japan’s permanent location, with conventions contracted for Labor Day weekend and commitments to remain there through 2030. San Japan continues to be one of the largest fan-run conventions in the South Texas region, bringing out 32,000 unique attendees to downtown San Antonio as of 2025.
