Koyama was a special guest at SakuraCon 2016.

SakuraCon 2016 was a very lackluster convention. Its guest list that was furnished by its corporate sponsors like Aniplex demonstrate how far a convention can really go downhill once it fully embraces corporate influence. Sponsored guests are featured on whatever new anime or manga a distribution company is trying to promote, rather than people that most convention attendees want to meet.

Koyama signed along with Hiroyasu Kobayashi. They both seemed to have a good time interacting with fans. I was really impressed with both of them. This was drawn on the last day of the convention, and staff was pressuring the guests to do quick sketches as their flight was leaving in a couple hours. Several people, myself included, asked for Baymax.
