It is a blue caravan with the Raimon logo on the front and a yellow lightning bolt on the side.
Raimon used it to recruit the ultimate players in all of Japan. It debuted on episode 28.
It can be used as transportation around the map in the game.
Inazuma Eleven GO
The Inazuma Caravan is used in GO as well, with a new appearance, by the new Raimon team. It was first used to bring the team to their match against Eito Gakuen. From there onwards, it brought the team to their match locations for the kanto region matches. After Raimon won the kanto region block, it brought the team to the Holy Liner, so they could use the liner to go to the Russian Roulette stadiums to play their matches.
