Career outline

Osamu Tezuka trained as a doctor and qualified as a physician, then chose to work as a manga artist. His breakout, the long-form children's adventure New Treasure Island (1947), is usually treated as the start of postwar story manga: a single ongoing narrative drawn with cinematic pacing, panel-by-panel cuts, and changes of camera distance, rather than the joke-page tradition that had dominated before the war.

Across the next four decades he produced an unusual range of work. Astro Boy turned a small-format children's serial into Japan's first weekly half-hour TV anime, broadcast from 1963. Phoenix was a multi-volume meditation on reincarnation that he returned to throughout his life. Black Jack, a series about a renegade surgeon, used Tezuka's medical background as a structural device. Buddha retold the life of Siddhartha Gautama. Adolf, a serialised political thriller, ran in a general-audience magazine and is often cited as evidence that he could carry adult literary work as well as children's adventure.

Stylistic characteristics

Tezuka's most-copied innovation is graphic: the large, expressive eyes that became standard in postwar manga. He has said he was influenced by early Disney and Fleischer animation, particularly Bambi and Betty Boop. The style turned out to suit a comics page that needs to convey emotional state quickly, and it was widely adopted, then repeatedly reworked, by his successors.

Less obvious but equally important is his approach to panel grammar. Tezuka borrowed from cinema: establishing shots, cuts to detail, silent panels that hold a beat, and changes of camera angle within a single scene. He treated the page as something a reader watches as much as reads. The result is the cinematic, fast-moving style that other artists then took further.

Tezuka also reused a small repertory cast across very different works - the "Star System" in which the same drawn character appears as a different person in another series. This gave his oeuvre a sense of internal coherence and made him easy to recognise even when reading new material.

Influence

There are two reasons Tezuka is often described as the "god of manga". First, he set the basic visual vocabulary that almost every later artist either adopted or pushed against. Second, his production company, Mushi Production, helped invent the cost structure of TV anime: short cycles, limited animation, fixed fees, weekly broadcast. That structure made anime financially viable - and bequeathed many of its long-running problems with overwork and tight budgets.

Among the artists who openly cite Tezuka as a starting point are Shotaro Ishinomori, Go Nagai, and Naoki Urasawa, whose Pluto reworks an Astro Boy storyline at adult-thriller scale. The manga art style page describes the visual conventions Tezuka helped lock in.
