Japan’s place on the F1 calendar has been confirmed with the release of the draft 2019 championship schedule.
Suzuka has agreed a new three-year deal until 2021, having been the country’s sole host venue since 2009.
The German GP has also been retained, with Hockenheim to again stage the race in July. It will be the first time since 2013-14 that Germany has held races in consecutive years.
The season will start a week earlier, and finish later – on December 1. There will be no repeat of this year's triple-header of races.
“The renewal of the Japanese Grand Prix and the confirmation of the German Grand Prix are both examples of our direction to place fans at the heart of Formula One, a vision shared with all our promoters," F1's managing director of commercial operations Sean Bratches said Friday.
The announcement comes just four weeks ahead of Suzuka's 30th anniversary staging of the Japanese GP.
"We are excited for the future and hope that the Suzuka Circuit continues to remain a fan favourite around the world, while continuing to contribute positively toward the prosperity of motor sports in Japan,” said Susumu Yamashita, president of track operator MobilityLand Corp, a subsidiary of new race title sponsor Honda.
This year's race will be Honda's first home GP in partnership with Toro Rosso – and next season it will also be providing engines for senior team Red Bull.
Meanwhile, Mercedes-Benz will be title sponsor for the 2019 German GP, with support from German automobile clubs ADAC and AvD and the German Minister for Transportation and Digital Infrastructure.
"The intensive, direct contractual discussions between Formula 1 and us in recent weeks have always been trusting, constructive and solution-oriented - the agreement reached is proof of this," said Georg Sailer, CEO of race promoter Hockenheim-Ring GmbH.
"We would also like to thank our long-standing partner Mercedes Benz in particular for its commitment as title sponsor which made the agreement possible in the first place.”
Mercedes F1 team principal Toto Wolff said the popularity of this year's race showed that Hockenheim should remain on the calendar.
"It was therefore important for us to do everything in our power to ensure that our home race will take place again next year," he said.
The calendar will feature a record 21 races for the third time, following this season and 2016.
China will have the honour of staging the 1,000th grand prix since F1 started in 1950, to be held on April 14.
