Harry Fujiwara (born May 4, 1935) is an American former professional wrestler and manager, best known by his ring name Mr. Fuji. He was infamous for often throwing salt in the eyes of face wrestlers. Although he was billed as Japanese, he is a Japanese-American born in Hawaii.

Fujiwara made his professional wrestling debut on December 15, 1965 in his native Hawaii under the ring name Mr. Fujiwara. He won his first championship, the NWA Hawaii Tag Team Championship, with Curtis Iaukea on January 7, 1966. He shortened his ring name to Mr. Fuji and toured many territories, including Don Owen's Portland, Oregon based NWA Pacific Northwest Wrestling where he won many championships.

Fuji debuted in Vince McMahon, Sr.'s World Wide Wrestling Federation in 1972 as a heel. He formed a tag team with Professor Toru Tanaka and the duo were managed by Grand Wizard. Tanaka provided his physical massive strength and Fuji brought his devious ring psychology to the team, which earned him the nickname "The Devious One". Fuji used to throw salt in his opponent's eyes, which earned him victories. They defeated Sonny King and Chief Jay Strongbow on June 27, 1972 for their first World Tag Team Championship. They quickly ascended to the main event status, defending the titles against WWWF World Heavyweight Champion Pedro Morales and Bruno Sammartino on several occasions, throughout the year. During the feud, Fuji earned a shot at the WWWF title against Morales on August 22 but lost by count-out. They reigned for eleven months, making them the third longest WWWF World Tag Team Champions in history. They would lose the titles to Tony Garea and Haystacks Calhoun on May 30, 1973.

Mister, usually written in its abbreviated form Mr or Mr. (American English), is a commonly used English honorific for men under the rank of knighthood. The title derived from master, as the equivalent female titles, Mrs., Miss, and Ms, all derived from the archaic mistress. The title master was retained and used for boys and young men, but is now less commonly used. The plural form is Misters, or the abbreviation Messrs (UK) or Messrs. (US) ( /ˈmɛsərz/). This is an English abbreviation of the French "messieurs" (French pronunciation: [mesjø]), sometimes pronounced /ˈmɛsərz/ in English.

When addressing someone directly: Mr. is usually used with the last name only ("May I help you, Mr. Thompson?"). In other circumstances, it can be used with either the last name or the full name ("This is Mr. John Smith."; "Would you please help, Mr Smith?"). In formal written address, it is usually used along with the full name, or with initials and surname.

When a man's name is unknown, "mister" is sometimes used informally by itself in direct address, as in, "Hello, mister," or "Are you all right, mister?" rather than the standard form of address, "Sir". Though not necessarily meant disrespectfully, such use may to some people seem rude.
