In conjunction with Kaiju vs Heroes, an in-depth exhibition (on view through July 7) celebrating the legacy of kaiju (monster) master Mark Nagato, JANM is hosting the day-long Kaiju-Con. As the dazzling exhibition traces the explosive cultural history and modern obsessions of the monster genre in art and cinema ? and of course, toys, toys, toys ? so today's all day confab combines screenings of vintage Godzilla, with hands-on illustration and toy workshops, conversations, vendors, exhibition tours and a higher than usual tolerance for folks showing up in costume. The day's events are ticketed and include exhibition admission; the outdoor screening of the 1964 kitsch-tastic masterpiece Mothra vs. Gidzilla ?is free.

Japanese American National Museum, 100 N. Central Ave., Little Tokyo; janm.org; Sat., June 15, 11am-5pm; $20-$30.
