This is a complete set of 54 issues of "Kokutetsu Tsushin," the Japan National Railways Public Relations Department's internal publication, published from 1974 to 1984. The content is similar to an internal newsletter, and it's a valuable resource for understanding the JNR era, including articles on railway technology, vehicle introductions, employee activities, and limited express trains. There is some yellowing, staining, and some writing, but it does not interfere with reading. The condition is generally good for a used book. Recommended for railway enthusiasts, researchers of the Showa era, and collectors.
