The Japanese motorcycle Grand Prix (日本グランプリ) is a motorcycling event that is part of the FIM Grand Prix motorcycle racing season.

The main venue who held the races for years was the Suzuka Circuit, until it permanently was replaced by the Mobility Resort Motegi from 2004 onwards after the circuit faced criticism for its short runoff areas and dangerous trackside barriers, causing the death of Japanese rider Daijiro Kato and the injuries of Marco Melandri and Alex Barros at the 2003 Japanese Grand Prix. As a result, Suzuka was faced with making considerable safety alterations to avoid a possible strike by the riders – many of whom believed the 240 hp motorbikes had outgrown the tight circuit. The FIM stated that the modifications would not be completed before 2005 and that, therefore, the 2004 Japanese Grand Prix would be held at Motegi, but Suzuka has not appeared on the calendar since.^[1]

The 2020 and 2021 races were cancelled due to the outbreak of COVID-19.^[2]
