What's Up Connection (1990)

Original title: てなもんやコネクション

When a Hong Kong teenager from a poor family wins a trip to Japan, he unleashes a chain of events that will soon bring him from his secluded fishing village to Tokyo. On the way, he connects with a barely competent tour guide and a gender-fluid pickpocket. Upon returning home with this merry band of schemers, he and his family of counterfeiters discover that a multinational conglomerate led by a ruthless Japanese developer has found the village, and is determined to raze it to build the new center of world trade.
