League sources say that the Golden State Warriors are tentatively scheduled to make a preseason trip to Japan next season. It is difficult to set such plans in stone in the current climate, given the many variables in trying to project the state of international travel 12 months from now amid a worldwide fight against the COVID-19 virus, but you can bank on the Warriors going to Tokyo as soon as conditions cooperate. The e-commerce company Rakuten, founded in Japan in 1997, is a major Warriors sponsor.
