The Mynavi ABC Championship(マイナビABCチャンピオンシップゴルフトーナメント,Mainabi ei-bī-shī champyon gorufu tōnamento?) is an annual event on the Japan Golf Tour. It is played at the ABC Golf Club in Katō, Hyōgo, usually in October. It was founded in 1971 as a Japan vs. United States team match (there was also individual prize money and the event counted as an official win on tour). In 1988, it became a full-field individual event. The event is sponsored by Asahi Broadcasting Corporation and Mynavi Corporation.
