The Japan Open Golf Championship (日本オープンゴルフ選手権競技, Nihon ōpun gorufu senshu kenkyōgi) is Japan's national open golf championship. Founded in 1927, it is one of the oldest professional golf tournaments in Japan.^[1]

The Japan Open is one of the three richest tournaments on the Japan Golf Tour, with a prize fund of ¥210 million in 2022. Between 1992 and 2021 it was the tour's designated "Flagship event" for the purposes of the Official World Golf Ranking, with a minimum winner's points allocation of 32 points.

The winner also receives an invitation to the following year's Open Championship.
