Five Nine (also referred to as 59) is a monthly magazine published in Tokyo, Japan.[1][2] The magazine covers topics related to amateur radio DXing and contesting. The magazine is published in Japanese and draws its subscription base primarily from Japan. The name of the magazine is derived from the international amateur radio RST code report of 59, indicating the highest level of signal readability and signal strength. The 59 signal report is commonly used in radio DXing, regardless of the actual signal readability or strength of the station receiving the report.

The magazine organizes, adjudicates, and publishes the results of an annual international radio competition, the Japan International DX Contest. The Japan International DX Contest focus on encouraging communications between amateur radio stations in Japan with other amateur radio stations around the world.
