During The King of Iron Fist Tournament 5, Ganryu lost his way and stumbled upon the Mishima Zaibatsu's laboratories. Within it, he found a disc containing research data concerning a Reforestation Program. He hoped Julia would agree to marry him if he brought her the data, and he proposed to her. However, Julia turned him down and left with the disc.
After that, Ganryu returned to Hawaii and opened a restaurant called Chanko Paradise. But the restaurant did not do well and Ganryu found himself in financial distress. It was then that he discovered news of another King of Iron Fist Tournament. He decided to participate in the tournament in order to advertise his restaurant, Chanko Paradise.
