The beating of the drums Saturday morning on Tokyo's Ryogoku district will herald the opening of the 15 day sumo tournament on Sunday, May 14.
    Grand Champions Haguroyama and Azumafuji are in fine fettle and should give a good account of themselves.
    The wrestler who will be really watched by fans, however, will be Champion Chiyonoyama who won the last two tournaments. If he should make it three in a row, the chances are strong that the Grand Championship may be his.
