Fernando Alonso will not participate in the first practice session of the Japanese Grand Prix due to the birth of his first child. The team's reserve driver, Jak Crawford, will drive the car in one of the team's mandated rookie sessions. Aston Martin has had a difficult start to the season due to reliability and performance issues with their Honda engine, and the car is also behind on development after its design was started late. Honda's first-order issue is a severe vibration from the engine, leading to failures in the battery. The Japanese GP is held on their own Suzuka track, built on the orders of Honda founder Soichiro Honda in the 1960s.
