Usually a driver who wants to take part in FP1 would apply for a free-practice only superlicence and complete 300km of running in an F1 car beforehand to qualifying.
However, as reigning Super Formula and Super GT champion Yamamoto comfortably satisfies the requirement for an outright F1 superlicence, which he has obtained, simplifying the process.
The last Japanese driver in F1 was Kamui Kobayashi in 2014, while honda last had a homegrown driver behind the wheel of one of its cars when Takuma Sato raced for the Super Aguri team in the 2008 spanish grand prix.
honda wants a driver to race in F1 again but its highest-placed proteges on the F1 feeder series radar have so far failed to secure the necessary superlicence points for honda to take advantage of its relationship with red bull and its junior team toro rosso.
Some talks have taken place about whether Yamamoto would be viable, but he would be a considerable gamble aged 31 and having never raced in europe.
