Go Nagai

Go Nagai is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Go Nagai rather than just read about it. In short: Kiyoshi Nagai (永井潔, Nagai Kiyoshi; born September 6, 1945), better known by the pen name Go Nagai (永井 豪, Nagai Gō), is a Japanese manga artist and a prolific author of science fiction, fantasy, horror, and erotica. He made his professional debut in 1967 with Meakashi Polikichi, but is best known for creating popular 1970s manga and anime series such as Cutie Honey, Devilman, and Mazinger Z.

Key takeaways

  • Go Nagai belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Go Nagai to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Go Nagai from memory before moving on to harder problems.

Reference excerpt

Kiyoshi Nagai (永井潔, Nagai Kiyoshi; born September 6, 1945), better known by the pen name Go Nagai (永井 豪, Nagai Gō), is a Japanese manga artist and a prolific author of science fiction, fantasy, horror, and erotica. He made his professional debut in 1967 with Meakashi Polikichi, but is best known for creating popular 1970s manga and anime series such as Cutie Honey, Devilman, and Mazinger Z. He is credited with creating the super robot genre; designing the first mecha robots piloted by a user from within a cockpit with Mazinger Z; as well as helping pioneer the magical girl genre with Cutie Honey; the post-apocalyptic manga/anime genre with Violence Jack; and the ecchi genre with Harenchi Gakuen. In 2005, he became a Character Design professor at the Osaka University of Arts. He has been a member of the Tezuka Osamu Cultural Prize's nominating committee since 2009.

Life

Early life Go Nagai was born on September 6, 1945 in the Ishikawa Prefecture city of Wajima. He is the son of Yoshio and Fujiko Nagai (永井芳雄・冨士子), and the fourth of five brothers. His family had just returned from Shanghai. While he was still in his early childhood, he along with his mother and his four brothers moved to Tokyo after the death of his father. As a child, he was influenced by the work of Gustave Doré (specifically, a Japanese edition of the Divine Comedy), Shirato Sanpei and Osamu Tezuka (Nagai's brother Yasutaka gave him a copy of Lost World). He graduated from the Metropolitan Itabashi High School of Tokyo. While passing his ronin year in a prep school in order to earn placement at Waseda University, he suffered a severe case of diarrhea for three weeks. Aware of his own mortality, he wanted to leave some evidence that he had lived, by doing something that he liked as a child: working on manga. He was determined to create one work of manga in what he thought were his last months. As Nagai prepared for the task, he went to the hospital, where he was diagnosed with catarrh of the colon, and soon healed. But this was the turning point in his life. Convinced that he would continue working on manga, he stopped attending school after three months and started living as a rōnin. With the help of his brother Yasutaka, he created his first manga works. Despite the fact that his mother opposed his manga aspirations, he submitted his works for publication, accumulating many rejections. It is said that when the young Nagai submitted his tables to publishers, his mother secretly convinced publishers to reject them. However, his work was noticed by Weekly Shōnen Sunday, which contacted Shotaro Ishinomori. Thanks to some trial manga he created with the help of Yasutaka, Nagai was finally accepted into the studio of Ishinomori in 1965. The trial manga was about a science fiction ninja, and was a prototype for a different story, Kuro no Shishi. Nagai was 19 years old when he made this work; it started at 15 or 16 pages and ended up being 88 pages long after a year, and was untitled at that time. Ishinomori saw this work and praised Nagai for it, but commented that the design was too chunky and he should improve it a little. Two or three days later, Nagai was invited to become an assistant to Ishinomori and this work was forgotten until 2007, when it was published in the magazine Comic Ran Twins Sengoku Busho Retsuden (コミック乱 TWINS 戦国武将列伝) by LEED under the name Satsujinsha (殺刃者 (さつじんしゃ)). His professional career began in 1967, despite the opposition of his mother.

First works

After working as assistant of Shotaro Ishinomori, his very first professional manga work was Meakashi Polikichi (目明しポリ吉 or 目明かしポリ吉), a very short gag comedy one-shot, published in November 1967 in the magazine Bokura by Kodansha. Almost at the same time, this was followed by the manga adaptation of Tomio Sagisu's TV anime Chibikko Kaiju Yadamon (ちびっこ怪獣ヤダモン, "Little Monster Yadamon"), also published in 1967 in the same magazine. A common misconception is that Kuro no Shishi ("Black Lion") was his first manga work; while not entirely false, what Nagai really made two years earlier than Meakashi Polikichi, was only a draft for what would later be Kuro no Shishi, which would not be actually published until 1978. His first works consisted entirely of short gag comedy manga. This would change with Harenchi Gakuen.

Worked examples

Example 1 — a first encounter with Go Nagai

Start with the simplest possible case. Write down what Go Nagai claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Go Nagai before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Go Nagai ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Go Nagai

In research
Go Nagai appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Go Nagai in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Go Nagai is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1945 births, Academic staff of Osaka University of Arts, Anime character designers, so understanding it makes those chapters shorter.
In everyday life
Look for Go Nagai outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
