Leiji Future was held on December 3 at Tokyo Culture Center. Originally an annual event, but held a little more sporadically in recent years, Leiji Future is a tribute to all things Leiji Matsumoto. It usually includes sellers of related merchandise, panels, screenings of old tv material, and a sketch & autograph session by the man himself (usually projected on a big screen so attendees can watch him work his magic).
The following is a few pics taken at Leiji Future 2017. You can hear our report of the event at the 1:12:55 mark of ep.96 of the SpeakerPODcast.
