Comic Market 108 Highlights: Attendance Trends, Cosplay and Yostar Booth Report
During the mid-August 2026 event cycle, Comiket 108 drew hundreds of thousands of attendees over two days in the rain, marking a significant visitor drop from the previous gathering according to MANTANWEB reporting. Amid the soaked rooftop cosplay zones, Yostar deployed one of the venue’s largest merchandising setups to spotlight its upcoming title Azur Promilia, while prominent cosplayers like Stanmi drew heavy crowds dressed as Gilgamesh from the Fate franchise as detailed by KAI-YOU and Sponichi Annex.
Weather Impacts and Attendance Shifts at Comiket 108
The two-day summer convention faced severe logistical headwinds from persistent rain, depressing overall gate figures compared to earlier iterations. MANTANWEB confirmed that total attendance settled at hundreds of thousands, representing a noticeable decrease in visitors from the prior event. Despite the precipitation, open-air sectors remained active. Sponichi Annex reported that the outdoor rooftop cosplay area stayed heavily populated on the opening day, featuring intricate fan and professional creations including a large-scale representation of the robot soldier from Castle in the Sky and a highly detailed depiction of Satoru Gojo.
Yostar Commands Floor Space with Azur Promilia Showcase
Commercial scale dominated the convention’s corporate halls, where publishers vied for consumer attention through massive retail footprints. Yostar established one of the largest on-site merchandising booths within the exhibition center, dedicating its main floor presence entirely to the promotion and product rollout of Azur Promilia.
High-Profile Cosplay Drives Social Media Engagement
Celebrity and influencer appearances added significant cultural momentum to the convention floor. KAI-YOU noted that internet personality Stanmi made a high-profile appearance on-site, appearing in full costume as the character Gilgamesh.
