Diameter: Approximately 31 cm Height: Approximately 11 cm The commemorative item shown in the image is from the completion and opening of the Japanese National Railways (JNR) Ōsumi Line. Overview Line Name: JNR Ōsumi Line (between Shibushi Station and Kokubu Station) Section: The commemorative item specifically commemorates the opening of the section between Kokubu Station and Umigatasen (Kokubu to Umigata Onsen). Date: This section opened on September 9, 1972, completing the entire Ōsumi Line. History: However, due to the already widespread use of automobiles at the time of its opening, ridership did not increase, and the entire line was abolished just 15 years later, on March 14, 1987. This item is a valuable commemorative piece that conveys a historical moment of the railway that once ran on the Ōsumi Peninsula. This item has been stored for a long time, so there are minor scratches and stains. Please check the photos.
