I do not have much information about the Japanese F3. However, I am going to be interested in 2019 season since one of the drivers I have been following in open-wheel ladder is going there, Sacha Fenestraz (French-Argentinian driver).
I cannot even find the calendar for next season. I will appreciate if someone can share it.

Besides Fenestraz other drivers took part in the tests like Callum Ilott, Harrison Newey and Lucas Auer.
