3,000 fans watch Harumafuji perform ring-entering ceremony at Meiji Shrine

YOI-SHO ! Omedetou Yokozuna Harumafuji!

one holding a fake samurai sword and acting as a guard,

Actually since real swords are illegal this is the best they can do, but use of the word "fake" makes it seem like a cheap toy. The facsimiles have the weight, heft and appearance of real swords and are made with a considerable degree of craftsmanship, but their edges aren't sharp. Anyway during the ceremony the sword held by the tachimochi remains sheathed throughout.

well done , so well done. how cool is this champion
