Now and again I say to myself "You know what this world needs? More blog posts on sumo." So here's a good Washington Post piece about the rise of—wait for it—blond sumo wrestlers, who, it's hoped, will "become a metaphor... for a reluctantly globalizing Japan." But is it? Everyone's always wondering, after all, when Japan plans on opening the floodgates and letting in immigrants, so as to avoid becoming a country filled only with senior citizens—and the pension burden that comes with that—but it's doubtful sumo will drive the needed cultural change here. Japan has had foreign-born wrestlers for years, including Mongolian and Hawaiian yokozunas, but that doesn't seem to have changed much, substantially. Still a fairly xenophobic place. This is a problem too.
