Matsukawa derailment: Unknown saboteurs cause a passenger train to derail and overturn in Fukushima Prefecture, Japan, killing three crew members and igniting a political firestorm between the Japanese Communist Party and the government of Occupied Japan that will eventually lead to the Japanese Red Purge.

Matsukawa derailment

The Matsukawa derailment occurred at 03:09 AM on August 17, 1949 when a Tōhoku Main Line passenger train derailed and overturned between Kanayagawa and Matsukawa stations in Fukushima Prefecture of Japan, killing three crew members. Together with the Mitaka and Shimoyama incidents, it was one of three major criminal cases involving allegations of sabotage blamed by the government on the Japanese Communist Party and the Japan National Railway Union in the immediate post-war era. Twenty people were arrested and seventeen were convicted in 1953, but eventually all were acquitted on appeal, and the case was closed without determining the real cause in 1970.

Tōhoku Main Line

The Tōhoku Main Line is a 575.7-kilometre-long (357.7 mi) railway line in Japan operated by the East Japan Railway Company. The line starts from Tokyo Station in Chiyoda, Tokyo and passes through such cities as Saitama, Utsunomiya, Fukushima, and Sendai, before reaching the end of the line in Morioka. The line originally extended to Aomori, but was truncated upon the extension of the Tōhoku Shinkansen beyond Morioka, which mostly parallels the Tōhoku Main Line. A portion of the Tōhoku Main Line is also shared with the Keihin–Tōhoku Line and the Saikyō Line.

Fukushima Prefecture

Fukushima Prefecture is a prefecture of Japan located in the Tōhoku region of Honshu. Fukushima Prefecture has a population of 1,771,100 and has a geographic area of 13,783.90 square kilometres (5,321.99 sq mi). Fukushima Prefecture borders Miyagi Prefecture and Yamagata Prefecture to the north, Niigata Prefecture to the west, Gunma Prefecture to the southwest, and Tochigi Prefecture and Ibaraki Prefecture to the south.

Japanese Communist Party

The Japanese Communist Party is a communist party in Japan. Founded in 1922, it is the oldest political party in the country. It had 250,000 members as of January 2024, making it one of the largest non-governing communist parties in the world. The party is chaired by Tomoko Tamura, who replaced longtime leader Kazuo Shii in January 2024.

The Red Purge was an anticommunist movement in occupied Japan from the late 1940s to the early 1950s. Carried out by the Japanese government and private corporations with the aid and encouragement of the Supreme Commander for the Allied Powers (SCAP), the Red Purge saw tens of thousands of alleged members, supporters, or sympathizers of left-wing groups, especially those said to be affiliated with the Japanese Communist Party, removed from their jobs in government, the private sector, universities, and schools. The Red Purge emerged from rising Cold War tensions and the Red Scare after World War II, and was a significant element within a broader "Reverse Course" in Occupation policies. The Red Purge reached a peak following the outbreak of the Korean War in 1950, began to ease after General Douglas MacArthur was replaced as commander of the Occupation by General Matthew Ridgway in 1951, and came to a final conclusion with the end of the Occupation in 1952.
