Tōzen-ji

Tōzen-ji 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 Tōzen-ji rather than just read about it. In short: Tōzen-ji (東禅寺), is a Buddhist temple located in Takanawa, Minato, Tokyo, Japan. The temple belongs to the Myōshin-ji branch of the Rinzai school of Japanese Zen.

Key takeaways

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

Reference excerpt

Tōzen-ji (東禅寺), is a Buddhist temple located in Takanawa, Minato, Tokyo, Japan. The temple belongs to the Myōshin-ji branch of the Rinzai school of Japanese Zen. One of the four great Zen temples of Edo, it is best known in history as the location of the first British legation in Japan during the Bakumatsu period and the site of a number of incidents against foreigners by pro-sonnō jōi samurai. The temple's precincts were designated a National Historic Site in 2010.

History The temple was established in 1610 in Akasaka by Ryōnan Zenji, and its name comes from the Dharma name of Itō Sukenori, daimyō of Obi Domain in Hyūga Province (preset day Miyazaki Prefecture). In 1636 it was relocated to its present location. At the time, the temple was directly on Edo Bay and for that reason was nicknamed Kaijō Zenrin (literally, "the Zen forest above the sea"). During the Edo Period it served as the bodaiji for a number of daimyō clans, including the:

Date clan of Sendai Domain Date clan of Uwajima Domain Date clan of Iyo-Yoshida Domain Ikeda clan of Okayama Domain Ikeda clan of Akō Domain Ikeda clan of Kamogata Domain Ikeda clan of Ikusaka Domain Suwa clan of Suwa Domain Matsudaira clan of Kanō Domain Oda clan of Yanagimoto Domain Inaba clan of Usuki Domain Mōri clan of Saiki Domain

The First Tōzenji incident

One of the provisions of the 1858 Anglo-Japanese Treaty of Amity and Commerce was that a representative of the British government would be permitted to reside in Edo. Rutherford Alcock was appointed Consul-General in Japan and selected Tōzen-ji to be used as the site of the British legation. It had been the policy of the Tokugawa Shogunate to commandeer temples for temporary use by foreign dignitaries, and Alcock felt that Tōzen-ji was of a suitable size and status. Japanese authorities were against the choice of Edo and advised Alcock to settle in Yokohama, especially as Tōzen-ji was located at the entrance to the Tōkaidō, the busiest and most important highway in Japan, and was therefore exposed to possible attacks. Alcock would not be deterred and the British legation was opened in 1859. In January 1860, Kobayashi Denkichi, the native interpreter of Rutherford Alcock, was murdered at the gate of the legation by two rōnin, foreshadowing further trouble which was to come. In May, Alcock returned to Edo from a visit to Nagasaki. Although the Shogunate had requested that he return by ship due to security reasons, he insisted on traveling overland to uphold one of the provisions of the treaty, namely that the movement of diplomats within Japan not be restricted. This greatly incensed the sonnō jōi party, especially a number of extremist rōnin formerly of Mito Domain. Led by Ariga Hanya, a number of rōnin assembled at the Toraya inn at Shinagawa-juku, and made their attack on the night of July 5, 1861 at 10 PM. Within the legation, some of the staff had stayed awake to follow the passage of a comet while Alcock slept in his apartments. There was a squad of sentries guarding the legation from Nishio Domain and Yamato-Kōriyama Domain but no particular precautions had been taken. The situation had returned to normal after the events of 1860 and no one suspected an imminent attack. When the Mito rōnin stormed the legation, the Japanese sentries fought back vigorously, killing three (including Ariga) and capturing three others. Two of the defenders were killed, and ten wounded, including George Morrison and the writer Laurence Oliphant, who were later sent back to England to recover. Alcock had time to load his revolver and fire a few shots before the battle was over. Of the three captured rōnin, one was executed by beheading and two committed seppuku. Of those who escaped the battle, four were found at the Toraya inn (of whom one committed seppuku rather than surrender, two were captured and committed seppuku, and one was executed), two were later killed during the Sakashitamon incident and one at the Tenchūgumi incident, and two more were killed at other locations. Only two of the participants survived until after the Meiji restoration. Alcock, who had bitterly protested the presence of the Japanese guards as a nuisance and accused them of being nothing more than spies for the Shogunate finally realized the depth of anti-foreign sentiment. He threatened that he would use the attack as a casus belli unless the shogunate agreed to permit a British garrison to be stationed at the legation, the number of Japanese guards increased, and compensation of $10,000 to be paid. The shogunate was forced to concede to all of these demands. Even so, Alcock would later write in his memoirs that the Japanese guards assigned did nothing to fight the attackers and it was only by his own heroism and that of Morrison and Olipant that they were driven off - not mentioning the two dead and ten injured Japanese defenders. Sword cuts and bullet marks from the attack remain in the pillars of the main hall of the temple. Rutherford Alcock, the first British Minister to Japan, recorded his impressions of Tōzen-ji in his book, The Capital of the Tycoon (1863).

Worked examples

Example 1 — a first encounter with Tōzen-ji

Start with the simplest possible case. Write down what Tōzen-ji 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 Tōzen-ji 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 Tōzen-ji 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 Tōzen-ji

In research
Tōzen-ji 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 Tōzen-ji 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
Tōzen-ji is common in secondary-school and first-year university syllabi. It links to neighbouring topics 17th-century Buddhist temples in Japan, 1861 in Japan, 1862 in Japan, so understanding it makes those chapters shorter.
In everyday life
Look for Tōzen-ji 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.

Why does Tōzen-ji 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 Tōzen-ji?

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.
