They want to be prepared if head office in Japan contemplates a move back to the World Rally Championship, but stress that nothing is certain at this time.
A spokesman for Toyota Motorsport said: "We feel it would be helpful to go and see how the land lies in various championships. Second, we want to be prepared if and when we get a call from Japan to go and compete in a different championship. It's a fact-finding mission, we want to make sure we have a decent knowledge base to work from.
"At the moment, there's nothing coming from Japan to indicate that a move will be made into any championship, but we have to be ready if that changes."
Former Toyota F1 chief Jens Marquardt along with engineer Pascal Vasselon will attend Rally Portugal on May 28 - 30.
