Tankōbon in the context of "Akira (manga)"

Astro Boy, known in Japan as Mighty Atom (Japanese: 鉄腕アトム, Hepburn: Tetsuwan Atomu; lit. 'Iron-Armed Atom'), is a Japanese manga series written and illustrated by Osamu Tezuka. It was serialized in Kobunsha's Shōnen from 1952 to 1968. The 112 chapters were collected in 23 tankōbon volumes by Akita Shoten. Dark Horse Comics published an English translation in 2002. The story follows the eponymous Astro Boy, an android young boy with human emotions who is created by scientist Umataro Tenma in the likeness of his son Tobio after the latter's death in an accident. Eventually, Astro is sold to a robot circus run by ringleader Hamegg, but is saved from his servitude by Professor Ochanomizu. Astro becomes a surrogate son to Ochanomizu who creates a robotic family for Astro and helps him to live a normal life like an average human boy, while accompanying him on his adventures.

The series has been adapted into three anime series produced respectively by the first incarnation of Mushi Production and its direct successor Tezuka Productions, with a fourth in development. The manga was originally adapted for television in 1963 as Astro Boy, the first popular Japanese animated television series, which pioneered and embodied the aesthetics that have characterized anime in general. After enjoying success abroad, Astro Boy was remade in the 1980s as New Mighty Atom, known as Astroboy in other countries, and again in 2003. In November 2007, the titular character was named Japan's envoy for overseas safety.

Sailor Moon (Japanese: 美少女戦士セーラームーン, Hepburn: Bishōjo Senshi Sērā Mūn; originally translated as Pretty Soldier Sailor Moon, later Pretty Guardian Sailor Moon) is a Japanese manga series written and illustrated by Naoko Takeuchi. It was originally serialized in Kodansha's shōjo manga magazine Nakayoshi from 1991 to 1997; the 60 individual chapters (later reorganized into 52) and several side stories were compiled into 18 tankōbon volumes. Set in Tokyo in the 1990s, the series follows the adventures of a schoolgirl named Usagi Tsukino as she transforms into the eponymous character to search for a magical artifact, the "Legendary Silver Crystal" (「幻の銀水晶」, Maboroshi no Ginsuishō; lit. "Phantom Silver Crystal"). She leads a group of comrades, the Sailor Soldiers, called Sailor Guardians in later editions, as they battle against villains to prevent the theft of the Silver Crystal and the destruction of the Solar System.

The manga was written in conjunction with the airing of an anime series produced by Toei Animation, which was broadcast in Japan from 1992 to 1997. Toei also developed three animated feature films, a television special, and three short films based on the anime. A live-action television adaptation, Pretty Guardian Sailor Moon, aired from 2003 to 2004, and a second anime series, Sailor Moon Crystal, began simulcasting in 2014. The manga series was licensed for an English release by Kodansha Comics in North America, and in Australia and New Zealand by Random House Australia. The entire anime series has been licensed by Viz Media for an English-language release in North America and by Madman Entertainment in Australia and New Zealand.

Weekly Shōnen Magazine (Japanese: 週刊少年マガジン, Hepburn: Shūkan Shōnen Magajin) is a weekly shōnen manga magazine published on Wednesdays in Japan by Kodansha, first published on March 17, 1959. The magazine is mainly read by an older audience, with a significant portion of its readership falling under the male high school or college student demographic. According to circulation figures accumulated by the Japanese Magazine Publishers Association, the magazine's circulation has dropped in every quarter since records were first collected in April–June 2008. This is, however, not an isolated occurrence as digital media continues to be on the rise.

It is one of the best-selling manga magazines. By March 2008, the magazine had 2,942 issues, having sold 4.55 billion copies, with an average weekly circulation of 1,546,567. At an average issue price of ¥129 ($1.29), the magazine had generated approximately ¥590 billion ($5.9 billion) in sales revenue by March 2008. In addition, about 1 billion compiled tankōbon volumes had been sold by March 2008.
