Takanohana who was grand champion of sumo have retired because of his phisical capasity. Somebody said that "He was great! because he broke many record" but the others said that "He was contemptible person because he have not appear the stage many times even as he was the grand champion" In my opinion, I think he was still one of great sumo wrestler. Because he have made an age as "wakataka" with his brother. It is no exaggeration to say that his existing makes sumo wrestring to be still popular . I am worry about the future of Sumo wrestring.
