Reference excerpt

Nobutake Ōkōchi (大河内信威, Ōkōchi Nobutake; 24 July 1902 – 12 July 1990) was a Japanese art historian, critic and businessman who served as the fifth president of the Japan Ceramics Association from 1984 to 1990. Before that, he was also a sympathiser for the cause of the Japanese Communist Party.

Biography Although he did not enroll in a college or university, Ōkōchi was a member of the Urawa Higher literary group within the Shinjinkai. He studied at Tokyo Imperial University. Under the pseudonym of Shin'ichi Ogawa (小川信一, Ogawa Shin'ichi), he worked for the Vanguard Theatre (前衛座, Zen'eiza), a Japanese theatre dedicated to countering the bourgeoisie, in 1927, along with other people. In 1929, Ōkōchi, along with Kiyoshi Miki and others, formed the Proletarian Institute of Science (プロレタリア科学研究所, Puroretaria kagakukenkyūjo), in which he was the secretary general. In 1930, he solicited the fund for the cause of the Japanese Communist Party, for which Miki contributed to. One year later, he was also the secretary general of the Japan Proletarian Cultural Federation (日本プロレタリア文化連盟, Nihon puroretaria bunka renmei). He worked with other left-wing groups on the evolution of capitalism in the second part of Analysis of Japanese Capitalism (日本資本主義発達史講座, Nihon shihonshugi hattatsu shi kōza). During World War II, he worked for Riken as an executive in the Riken Konzern. After the Riken Konzern was disbanded, he began to study the history of ceramics. While publishing works on ceramics, he primarily published under the names of Nobutake Isono (磯野信威, Isono Nobutake), Fūsenshi Isono (磯野風船子, Isono Fūsenshi) or Fūsenshi Ōkōchi (大河内風船子, Ōkōchi Fūsenshi). Ōkōchi supervised the opening of the Kakiden Gallery in 1978. He served as the president of the Japan Ceramics Association from 1984, succeeding Kō Segawa, until his death in 1990.

Personal life Ōkōchi was the eldest son of Viscount Masatoshi Ōkōchi, the third director of Riken. His younger brother was Nobuhiro Ōkōchi. He was the first husband of actress Shizue Kawarazaki.

Worked examples

Example 1 — a first encounter with Nobutake Ōkōchi

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

In research: Nobutake Ōkōchi appears in astronomy 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 Nobutake Ōkōchi 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: Nobutake Ōkōchi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1902 births, 1990 deaths, 20th-century Japanese businesspeople, so understanding it makes those chapters shorter.
In everyday life: Look for Nobutake Ōkōchi 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.
