Tim Eldred over at Starblazers.com has written a fascinating article about the history of the early Yamato fandom and by extension the history of the first true fandom in anime history. See what fans had to do before the concept of the anime fan even existed, and the steps taken to organize and even save the first of many productions that would be overshadowed by the might of eventual-Ghibli-director Miyazaki.
Yamato’s fandom even plays an integral role in the very first Comic Market, which is only a hint of the profound influence Yamato and its fans had on both sides of the anime industry.
It also sheds light on that Genshiken comic by Zetsubou-Sensei creator Kumeta Kouji depicting Ohno in various cosplay outfits at Comiket over the years. Her cosplay of Yuki from Yamato isn’t just early, it’s early.
