The Japanese Grand Prix will remain at Suzuka until at least the end of the 2024 season after Formula One and circuit owners announced a three-year contract extension on Saturday.
The figure of eight-track south-west of Nagoya first hosted a Formula One race in 1987 and has provided the decider for 11 drivers' championships.
"This extension is part of our long-term commitment to growing the sport in Asia, and we are pleased to be able to continue our successful relationship with Mobilityland," said Formula One chief executive Stefano Domenicali in a statement.
Mobilityland is a subsidiary of Honda.
Tsunoda scored points on his F1 race debut with Red Bull-owned AlphaTauri when he finished ninth in Bahrain last month.
He spoke afterwards about going to Suzuka with his father to watch the race, and being a fan of double world champion Fernando Alonso who is still on the grid with Renault-owned Alpine.
The circuit, which did not host a race last season due to the Covid-19 pandemic, will celebrate its 60th anniversary next year.
