着ぐけも (Costume Kemono / Kigukemo) 1
WikiFur records Kigukemo’s inaugural edition in 2010, but the day-level date, venue, admission and program details were not recoverable from the reviewed sources. The series was a Nagoya furry convention held on Saturdays and focused on kigurumi/kemono community and fursuit-making interaction.
