Arima Kinen
Until 1999 the Arima Kinen was open to Japanese trained horses only. However, the Japan Racing Association introduced a new condition in 2000 which allowed for the participation of a foreign trained horse, if it had won that year's Japan Cup (though, no horse eligible has ended up participating this race). The Arima Kinen was classed as a Domestic Grade I until 2006, and it was then promoted to an International Grade I in 2007. Consequently, it is now possible for more foreign trained horses to compete in the race. The maximum number of these was set at four in 2007, and this increased to six for the 2008 running.
