Development

 * Yasuo was designed by CertainlyT.
 * Yasuo is voiced by Liam O'Brien.
 * Yasuo is a masculine Japanese given name, the meanings are different depending on the Kanji used. The variants are: 保夫, "protective, preserve, husband", 安生, "tranquil; content, life, birth", 康郎, "happy, healthy, son; young man", 靖男, "calm; peaceful, son; male, baron", 泰雄, "great; exalted, superior, male", 八洲夫, "eight; many, continent; island, husband."
 * Yasuo is not his birth name. He was given this new name when he joined the sword school in an effort to steady his wild nature.
 * Judging by this, his name would be rendered as 安生 or 靖男 in Kanji, however, Riot decided the Kanji used for his name is 康夫. However, the Chinese servers instead write his name as 亚索.
 * Yasuo's appearance is most likely a reference to Musashi Miyamoto, a historical Japanese swordsman and wandering samurai. The facial appearance and ponytail in particular are very similar to popular artistic portrayals of Miyamoto, and his combat style is similar to Miyamoto's prior to his creation of his famous twin-sword style.
 * Yasuo's techniques and animations bear resemblance to Haoumaru, a sake-loving warrior from the game series Samurai Spirits/Samurai Shodown, who in turn is also based on Musashi Miyamoto.
 * This is further supported by Yasuo's taunt and joke animations; one of them involve spitting his drink on his blade, which Haoumaru also does to "bless it" before battle.
 * As another coincidental nod to Haoumaru, Yasuo's is named as Zhǎngāngshǎn in the Chinese servers (pronounced "Jah-ng gah-ng shah-n"; written as 斩钢闪 in Simplified Chinese and 斬鋼閃 in Traditional Chinese/Japanese), which literally means "Slashing Steel/Steel-Cutting Flash. The naming of this attack is the same as one of Haoumaru's Special Moves (which is his strongest one in terms of raw damage), the Ougi Zankousen (奥義 斬鋼閃, lit. Secret Skill Slashing Steel Flash).
 * His samurai motif also ties into his high critical strike chance passive, as a possible nod to many Samurai-based characters in most RPG/MMO settings who are focused on dealing as much damage as possible, especially with high critical hit chance involved. Said samurai/swordmasters may or may not be assassins, another MMO class that is heavily associated with high critical hit chance.

Quotes

 * Yasuo's quote "Ninjas... I hate those guys." is similar to quote "Noxians... I hate those guys".
 * Yasuo's quote "No cure for fools." is possibly a reference to this scene in Akira Kurosawa's film Yojimbo.
 * Yasuo's special taunt when near "Wuju? No, I wouldn't." is a reference to the latter's joke "Wuju... pass me that potion?".
 * In addition, the "Nice... sword... boots?" line is more than likely a reference to the popular pro as heck guide to Master Yi video.
 * His quote "A wanderer isn't always lost" is a reference to poem, which says "Not all those who wander are lost".
