Mimizuka

Mimizuka is a engineering 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 Mimizuka rather than just read about it. In short: The Mimizuka (耳塚; "Ear Mound" or "Ear Tomb"), which was renamed from Hanazuka (鼻塚; "Nose Mound"), is a monument in Kyoto, Japan. It is dedicated to the sliced noses of killed Korean soldiers and civilians, as well as those of Ming Chinese troops, taken as war trophies during the Imjin War.

Key takeaways

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

Reference excerpt

The Mimizuka (耳塚; "Ear Mound" or "Ear Tomb"), which was renamed from Hanazuka (鼻塚; "Nose Mound"), is a monument in Kyoto, Japan. It is dedicated to the sliced noses of killed Korean soldiers and civilians, as well as those of Ming Chinese troops, taken as war trophies during the Imjin War. The monument enshrines the severed noses of at least 38,000 Koreans and over 30,000 Chinese killed during Toyotomi Hideyoshi's invasions. The shrine is located just to the west of Toyokuni Shrine, the Shinto shrine honoring Hideyoshi in Kyoto.

History Traditionally, Japanese warriors brought back the heads of enemies slain on the battlefield as proof of their deeds. Nose collection in lieu of heads became a feature of the second Korean invasion. Originally, remuneration was paid to soldiers by their daimyō commanders based on the severed heads upon submission to collection stations, where inspectors meticulously counted, recorded, salted and packed the heads bound for Japan. However, because of the number of civilians killed along with soldiers, and crowded conditions on the ships that transported troops, it was far easier to just bring back noses instead of whole heads. Hideyoshi was especially insistent upon receiving noses of people his samurai had killed as proof that his men really were killing people in Korea.

Japanese chroniclers mention that during the Imjin War, the noses hacked off the faces of the massacred were also of ordinary civilians mostly in the provinces Gyeongsang, Jeolla, and Chungcheong. In the second invasion, Hideyoshi's orders were thus:

Mow down everyone universally, without discriminating between young and old, men and women, clergy and the laity—high ranking soldiers on the battlefield, that goes without saying, but also the hill folk, down to the poorest and meanest—and send the heads to Japan. One hundred sixty thousand Japanese troops had gone to Korea where they had taken 185,738 Korean heads and 29,014 Chinese ones, a total of 214,752. As some might have been discarded, it is impossible to enumerate how many were killed overall during the war.

The Mimizuka was dedicated September 28, 1597. Though the exact reasons as to its construction are not entirely known, scholars contend that during the second Japanese invasion of Korea in 1597, Toyotomi Hideyoshi demanded his commanders show receipts of their martial valor in the destruction, dispatching congratulatory letters to his high-ranking warriors in the field as evidence of their service. Hideyoshi then ordered the relics entombed in a shrine on the grounds of Hokoji Temple, and set Buddhist priests to work praying for the repose of the souls of the tens of thousands of Koreans from whose bodies they had come; an act that chief priest Saishō Jōtai (1548–1608) would hail as a sign of Hideyoshi's "great mercy and compassion." The shrine initially was known as hanazuka (鼻塚), Mound of Noses, but several decades later this would come to be regarded as too cruel-sounding a name, and would be changed to the more euphonious but inaccurate mimizuka (耳塚), Mound of Ears, the misnomer by which it is known to this day. Other nose tombs dating from the same period are found elsewhere in Japan, such as at Okayama.

Effect on modern foreign relations The Mimizuka is almost unknown to the Japanese public, unlike with the Koreans. The British historian Stephen Turnbull called the Mimizuka "Kyoto's least mentioned and most often avoided tourist attraction". A plaque, which was later removed, stood in front of the Ear Mound in the 1960s with the passage, "One cannot say that cutting off noses was so atrocious by the standard of the time." Most guidebooks do not mention the Ear Mound, and only a few Japanese or foreign tourists visit the site. The majority of visiting tourists are Korean—Korean tour buses are often seen parked near the Ear Mound. In 1982, not a single Japanese school textbook mentioned the Ear Mound. As of 1997, the mound is referred to in about half of all high-school history textbooks according to Shigeo Shimoyama, an official of Jikkyo, a publishing company. The publisher released the first Japanese text book mentioning the Ear Mound in the mid-1980s. The Education Ministry of Japan at that time opposed the description as "too vivid" and pressured the publisher to reduce the tone and also to praise Hideyoshi for religiously dedicating the Ear Mound to store the spirits of the killed people. In the 1970s under the Park Chung Hee administration, some of the officials of the South Korean government asked Japan to level the monument. However, most South Koreans said that the mound should stay in Japan as a reminder of past savagery. In 2005, the activity since the 1990s was described as:

Worked examples

Example 1 — a first encounter with Mimizuka

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

In research
Mimizuka appears in engineering 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 Mimizuka 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
Mimizuka is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures in Kyoto, Human trophy collecting, Imjin War, so understanding it makes those chapters shorter.
In everyday life
Look for Mimizuka 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.

Frequently asked questions

What is Mimizuka in simple terms?

The Mimizuka (耳塚; "Ear Mound" or "Ear Tomb"), which was renamed from Hanazuka (鼻塚; "Nose Mound"), is a monument in Kyoto, Japan. It is dedicated to the sliced noses of killed Korean soldiers and civilians, as well as those of Ming Chinese troops, taken as war trophies during the Imjin War.

Why does Mimizuka matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Mimizuka?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
