TOKYO,  Jan. 11 - The official spring tournament of the Japan Professional Sumo Association will open Wednesday, January 12, at the temporary Kokugikan ring in Hamacho Park, Nihonbashi, Tokyo.
    Particular attention will be paid by the fans to the performances of the new grand champion "yokozuna" Azumafuji, who will probably be the biggest wrestler of the tourney, weighing 373 pounds.
    Favorites for the championship in the coming 13 day competition include Azumafuji, Masuiyama and Saganohana although such veterans as Maedayama, Chiyonoyama and Kamikaze are reported to be in good condition.
    Special seats are reserved for Allied personnel. It is expected that the meet will draw the largest crowds since the end of the war.
