The Toyota Gazoo Racing driver had a troubled second half of the season with three different co-drivers occupying the right seat of his Yaris World Rally Car in consecutive events.
Dan Barritt led Katsuta to his first podium in the FIA World Rally Championship at the Safari Rally Kenya before injuring his back at the Rally Estonia.
He was replaced by Keaton Williams in Belgium, but the Briton was unable to compete in the EKO Acropolis Rally Greece for family reasons. Katsuta therefore did not start and Aaron Johnston, who had just split up with Oliver Solberg, jumped in for the next rounds in Finland and Spain.

While Katsuta and Johnston fell on both events, the Japanese believes the Northern Irish holds great promise.
When asked what will happen in the future, he replied, “I’m not sure. I’m pretty sure Aaron will do a very good job. I have no questions about this and Dan – I’ve been with him a long time. I am very happy with both of them.
“I want to continue with both of them, but I know I can only have one passenger. I have to choose. “
Barritt was at the RallyRACC – Rally de España earlier this month to write safety instructions for Katsuta.
“Before this rally,” said Katsuta, “Dan felt more comfortable, but after the rally I feel very comfortable with Aaron.”
Focusing on choosing a co-driver is an important process for Katsuta – as is returning to the speed he showed mid-season when he finished second in Kenya after a remarkably consistent start to the year.
“I have to find that trust again,” he said. “A lot happened in the middle of the season and now I have to forget that and drive the way I did again. I was disappointed in Spain, I made a mistake, but I feel like things are moving in the right direction. “
