Reference excerpt

The Omori bank robbery (大森銀行ギャング事件) was a bank robbery committed by members of the Japanese Communist Party in Ōmori-ku, Tokyo, Japan, in 1932. The bank robbery was dubbed the Omori Gang affair or the Red Gang Affair.

Background On 6 October 1932, three party members stole 31,700 yen from the Kawasaki Daihyaku Bank Ōmori Branch in an attempt to obtain funds for party operations. The plan was unknown to all but one member of the central committee. The robbery badly discredited the party in the eyes of the public. The government took full advantage of the incident and subsequent trial to portray the party as a nest of gangsters, leading to the destruction of the Party.

Perpetrators Yusho Otsuka, who was the brother-in-law of Hajime Kawakami, hatched a plan to procure desperately needed funds for the party. He and an accomplice held up the main branch of the Kawasaki Daihyaku Bank in Ōmori. He used Kawakami's younger daughter, Yoshiko, to "drive alongside him in the getaway car to lend an air of respectability to their group escape." Yoshiko and Otsuka were able to outwit the police. Biographer Yasutaka Saegusa believes that the writer Osamu Dazai was indirectly involved in the Omori Gang bank robbery. Others who were accused of being connected to the robbery included those arrested in the Atami raid of 1933.

Arrests The robbery put a high price on Otsuka's head. Otsuka decided to discontinue his visits to Kawakami. In October 1932 police arrested party members involved in the armed robbery.

Worked examples

Example 1 — a first encounter with Omori bank robbery

Start with the simplest possible case. Write down what Omori bank robbery 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 Omori bank robbery 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 Omori bank robbery 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 Omori bank robbery

In research: Omori bank robbery 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 Omori bank robbery 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: Omori bank robbery is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1932 crimes in Japan, 1932 in Japan, Bank robberies, so understanding it makes those chapters shorter.
In everyday life: Look for Omori bank robbery 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.
