The Origin of the Title
The name Bleach was chosen as a contrast to the black that the Shinigami in the series wear, as well as a reference to the Yin and Yang, white on black motif. It can be seen as a metaphor for breaking away from societal rules and constructs, which the main protagonist, Ichigo Kurosaki, seems to do quite regularly.
Snipe: Bleach's First Incarnation
When Kubo first created Bleach, he made Rukia the main character and armed her with a scythe, while giving all of the other characters guns. This original work was titled "Snipe," but after Kubo changed the weapons to swords, the title had to go as well. But you can still see Rukia with her scythe in the movie, Bleach: Fade to Black
Ichigo's Name
While most think that Ichigo's name comes from the Japanese word for strawberry, the kanji for his name (一護) actually roughly translates to "one who protects." Sounds like our Ichigo!
The First Character
The first character that Tite Kubo created in the series was not the main protagonist Ichigo, but the shinigami Rukia Kuchiki. She was originally created when Kubo felt like drawing a shinigami wearing a kimono.
Kenpachi's Hair Style
Captain Kenpachi Zaraki is easily one of the strongest and most violent of the Shinigami captains, and one of his most fearsome traits is his hair: he styles it in spikes every night after his bath, and he hangs bells on every one individually. However, the top hair spike is particularly tricky for him to reach, and it can take several hours for him to attach the bell.
Ichigo's Fashion Sense
When Kubo was in elementary school, he was fascinated by fashion design, so all of the designs in Bleach are ones Kubo himself thought up. After Bleach came out, the shop Urahara Soten in Tokyo began to produce and sell shirts worn by Ichigo in the anime.
Theme Songs
When Kubo draws for Bleach, he has hundreds of different CDs that he plays. Every character even has their own theme song! Ichigo's is "News from the Front" by Bad Religion.
The First Arrancar
The first Arrancar that Kubo created was Ulquiorra Cipher (whose theme song is "Moonshield" by In Flames). It makes sense that he's now a fan favorite!
Orihime's Powers
Orihime Inoue's powers manifest themselves in her blue, flower-shaped hairpins. Despite their cute appearance, these pins are the forms of six powerful fairies, the Shun Shun Rikka (盾舜六花, Six Flowers of the Hibiscus Shield) who are all named after different flowers: Ayame or Iris, Baigon or Ume, Hinagiku or Daisy, Lily, Shun'ou or Althea, and Tsubaki or Camelia.
Initial Rejection
When Kubo first proposed Bleach as a series for the Shonen Jump magazine, it was rejected. But Akira Toriyama, the creator of Dragon Ball, wrote a letter to Kubo to encourage him to continue the story. Thanks, Toriyama!
The Original Ichigo
Kubo originally designed Ichigo to have a more classic "nerdy" appearance, wearing glasses and without the orange hair. But after creating Ichigo's dark storyline, Kubo decided that it would be better to make the ginger delinquent we know and love today.
Renji's Accessories
Renji Abarai is probably one of the most fashionable Shinigami in Bleach. From his hair to his tattoos, he's out to make a statement. He also often sports expensive sunglasses from the Seireitei's popular shop Gin Tonbo, though they are often broken in battle. He dreams of one day wearing fashionable goggles of his own design.
Poor Kon
Kubo was inspired to create the character Kon after witnessing a young boy throw away a cheap stuffed toy his father had bought him instead of a more expensive version. Since Kon is an enhanced soul marked for elimination, this idea fits rather nicely with the cute stuffed lion in the series.
Chad's Tattoo
Though Yasutora "Chad" Sado is supposed to be of Mexican descent, the tattoo on his left shoulder reads "Amore e Morte," which means "Love and Death" in Italian.
More Music
Bleach has over 15 opening theme songs, and all of its theme songs and soundtracks were arranged by the famous Shirou Sagisu, who also composed the music for Neon Genesis Evangelion
Languages in Bleach
Kubo uses different languages for the different races in Bleach because of the way they sound to him. For instance, he uses Spanish for the Arrancar because it sounds passionate, and German for the Quincies for its more methodical tone.
Some Sensitive Race Issues
Kubo had originally named the character Yoruichi Shihouin Kuroneko, which literally translates to "Black Cat." However, because of the threat of sparking racial debate, Kubo decided to change her name to Yoruichi.
Passion for Architecture
Kubo has been known to admire architecture and other structural designs; so many of the Espada's names stem from those of famous architects. For instance, Ulqiorra's name comes from the name of the famous furniture designer Patricia Urquiola.
Uryuu's Pet Peeve
In addition to being the last Quincy, Uryuu Ishida is also a master craftsman, known for his sewing prowess. Despite his talent for making clothes, for some reason he hates buttons.
Filler
Because the anime version of Bleach cut out so many earlier arcs of the manga in order to reach the Soul Society arc, many key character relations were simply glossed over or lost completely. Even worse, because the anime accelerated so far ahead of the manga, it required more filler episodes, which is what ultimately caused Bleach to consist of 45% filler episodes.
