What would happen if Nike got involved in this? I know there's a lot of players that are "big stars" who are endorsing the products that Nike makes, but would it make more money over in Japan? (Even though Nike is a international brand and makes already big money)
Japan is not a big market at all compared to the rest of Asia, especially China. Nike already has Asia covered. It is diminishing returns if they were to spend money just to get additional presence in Japan.
