Many thanks to Tokyo Fox who has posted photos of locations that appear in the Rain books on his website and to Barry Eisler for tweeting the link. At this point it is not clear if the Rain TV show will be filmed on location or in LA. Regardless, if the show is going to stay true to the book, I’d imagine they will be trying to find similar looking locations for the show.
The post is PT VI. At the bottom of the page, there are links to other posts in the series.
