Reference excerpt

Kyowa Kirin Co., Ltd. (協和キリン株式会社, Kyōwa Kirin Kabushiki Kaisha) is a Japanese pharmaceutical and biotechnology company under the Kirin Holdings, and was among the 40 largest in the world by revenue in 2012. The company is headquartered in Chiyoda-ku, Tokyo and is a member of the Nikkei 225 stock index.

History The forerunner of the present-day company was called Kyowa Hakko Kogyo Co., Ltd (協和醱酵工業株式会社, lit. 'Coordinated Fermentation Industry Share Company') and was established on July 1, 1949. The company merged with Kirin Pharma Co., Ltd., on October 1, 2008 to form Kyowa Hakko Kirin (KHK) with plans to spin off the bio-chemical business into Kyowa Hakko Bio. On July 11, 2014, the KHK subsidiary, ProStrakan Group (based in Scotland), acquired Archimedes Pharma from the Novo Nordisk Foundation for $394 million. In 2019, Kirin Holdings acquired 95% stake in Kyowa Hakko Bio which is Kyowa Kirin's subsidiary corporation. The entity was renamed "Kyowa Kirin Co., Ltd.", replacing its prior name of Kyowa Hakko Kirin Co., Ltd. In November 2022, Kyowa Kirin announced plans to spin its International Established Medicines portfolio, consisting of 13 brands, into a new joint venture with German company Grünenthal. The joint venture would expand Grüenthal's already extensive pain management portfolio, while Kyowa Kirin saw it as a financial benefit and an opportunity to expand the brands. In October 2023, Kyowa Kirin acquired a Britain-based biopharmaceutical company, Orchard Therapeutics, for $478 million, aiming to expand their portfolio.

Business segments and products

Pharmaceuticals business The company developed a method to make afucosylated monoclonal antibodies using a CHO cell line in which FUT8 has been knocked out; the company calls this its "Potelligent" platform. The company gained marketing approval in Japan in April 2012 for a monoclonal antibody drug called mogamulizumab which was developed using the platform.

Worked examples

Example 1 — a first encounter with Kyowa Kirin

Start with the simplest possible case. Write down what Kyowa Kirin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Kyowa Kirin 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 Kyowa Kirin 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 Kyowa Kirin

In research: Kyowa Kirin appears in science 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 Kyowa Kirin 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: Kyowa Kirin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1949 establishments in Japan, Biotechnology companies of Japan, Companies in the Nikkei 225, so understanding it makes those chapters shorter.
In everyday life: Look for Kyowa Kirin 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.
