Seven out of ten South Korean professional basketball teams have called off scheduled off-season training in Japan.
Eight women's pro basketball and volleyball teams have also canceled or plan to cancel training in Japan and are scouting out local places to train instead.
Local sporting competitions are making similar moves.
