Two books covering City Pop are now in stocks on NeonMusic! "Disc Collection Japanese City Pop" covers guides and reviews to Japanese City Pop from the 1970s to 2010s. While "Asian City Music Disc Guide" covers City Pop in various eastern Asian countries such as Vietnam, Thailand, Indonesia, Hong Kong, Malaysia, Singapore, Philippines, China, Laos, Korea.
Do note that all the content are in Japanese. But it still makes for great referencing and are perfectly suited for a coffee table book.
