The Nakayama Daishogai (中山大障害) is a Group 1 steeplechase horse race in Japan open to thoroughbreds which are three-years-old or above.

It is run over a distance of 4100m (21⁄2 miles + 84 feet) at Nakayama Racecourse every year in late December.

Inaugurated as the Daishogai Tokubetsu in 1934, the Nakayama Daishogai had originally been run twice annually, once in the spring and once at the end of the year.

In 1999, the spring race was discontinued and replaced by the Nakayama Grand Jump.

[2] *There were two runnings of the Nakayama Daishogai in 2004, as the 2003 race was originally postponed due to weather.
