Waku Waku +NYC, a new “Japanese pop culture festival” launching this summer in Brooklyn, has announced father-and-son duo Takao Koyama and Makoto Koyama as guests.

Takao Koyama served as the scenario/scriptwriter on various movies and features for the Dragon Ball franchise during its heyday, including up through 2008’s Jump Super Anime Tour Special. In 2013, Koyama penned a blog post following his viewing of that year’s new film, Dragon Ball Z: Battle of Gods.

Makoto Koyama’s contribution to the franchise has thus far been as the scenario/scriptwriter for the 2011 Episode of Bardock animated adaptation.

Waku Waku +NYC will take place 29 August to 30 August 2015 in Brooklyn, NY at several locations in the Williamsburg and Greenpoint neighborhoods. Single day and weekend passes are available.
