Sato (March 13, 1871 - March 23, 1921) was an American vaudeville performer who flourished in the late nineteenth and early twentieth centuries.
His act was notable for its juggling of the comedic style and may be described as helping define the so-called "tramp" juggling style epitomized by W.
C.
Fields.
In fact, Sato and Fields are known from Fields' surviving correspondence to have maintained a bantering relationship in which the two traded gossip and ideas for their acts.
