Stage 01

Warm-Up & Activation

Before watching the video, discuss these questions with a partner or reflect on them individually. Try to use C1+ vocabulary in your answers.

1
When you think of the word economy, what images come to mind? How does the economy you live in today differ from economies of 200 years ago?
Think about: production, waste, consumption, trade, technology.
2
What do you know about Japan's Edo period (1603–1868)? What political or social features defined it?
3
What is a circular economy? Can you define it without using the word "circular"? Give a real-world example from your own country.
4
Is it possible for a society to be economically efficient and environmentally sustainable at the same time? Or are these goals in conflict?

Comprehension Questions

Answer in full sentences. Where possible, paraphrase rather than quote the video directly — this is a C1–C2 skill.

1
What time period does the Edo era cover, and what were its two defining political characteristics?
2
How did the city of Edo (present-day Tokyo) grow during this period, and why was this growth potentially dangerous from an ecological standpoint?
3
What role did Buddhist philosophy play in shaping the Shogunate's economic policies?
4
Describe at least three specific examples of how everyday materials were reused or repurposed in Edo society. What do these examples reveal about attitudes towards consumption?
5
How did the shimogoe system function, and why was it considered remarkable compared to European cities of the same era?
6
Roman Krznaric presents both the strengths and weaknesses of the Edo model. What were the main drawbacks he identifies? Do you think he is sufficiently critical?
7
In what sense does the video challenge the conventional definition of "economic efficiency"? What alternative definition does it implicitly propose?
Suggested Answer Key Teacher / Self-Study Use
  1. The Edo period spans 1603–1868. It was characterised by unified rule under the Tokugawa Shogunate and a policy of near-total foreign isolation known as sakoku.
  2. Edo grew from a minor castle town into one of the world's largest cities. This rapid urbanisation risked exhausting local resources and generating unmanageable waste — the very conditions that led to ecological collapse in other cities of the period.
  3. Buddhist values emphasising restraint, impermanence, and interconnectedness provided a philosophical basis for the Shogunate's promotion of low consumption, local production, and optimal use of resources.
  4. Examples include: kimonos worn by multiple people across generations, then used as rags, as baby nappies, as fuel, and finally their ash as fertiliser; used umbrellas, candles, paper, and pots were collected and repaired as occupations; human waste was sold to farmers. These practices reveal a culture in which discarding materials was seen as wasteful and even irresponsible.
  5. The shimogoe system involved city dwellers' human waste being purchased by surrounding farmers and applied to fields as organic fertiliser. This kept Edo exceptionally clean — a stark contrast to contemporary European cities, which were plagued by diseases stemming from improper waste disposal.
  6. Krznaric acknowledges that the Edo system depended on authoritarian social structures, rigid class hierarchies, and heavy restrictions on individual freedom. Answers will vary on whether his critique is thorough enough.
  7. The video challenges the idea that efficiency means maximising output and profit. It implies an alternative: efficiency as the optimal use of available resources with minimal waste — a systems-level, long-term view rather than a short-term financial one.

Language Focus: Sentence Transformation Exercises

Rewrite each sentence using the structure shown, keeping the meaning as close as possible to the original. Type your answer in the field below each item, then click Check to see the model answer.

Set A — Concessive Clauses  ·  although / despite / while / even though / however

Concessive clauses acknowledge a contrasting idea while maintaining your main argument — a mark of sophisticated C2 reasoning.

1
The Edo model was highly sustainable. It depended on authoritarian control.
→ Rewrite as one sentence beginning with Although
2
Japan was isolated from foreign trade. It managed to sustain one of the world's largest cities.
→ Rewrite as one sentence using Despite
3
The shimogoe system is often admired. It would be unacceptable in most modern urban contexts.
→ Rewrite as one sentence using While
4
Resources were scarce during the Edo period. Citizens found ways to reuse almost everything.
→ Rewrite as one sentence using Even though
5
Buddhist philosophy encouraged frugality. The Shogunate still had to enforce strict consumption laws.
→ Rewrite as two sentences, beginning the second with However
Set B — Active → Passive  ·  academic distancing & objectivity

Rewrite each active sentence in the passive. Keep the same tense. Include by + agent only where it is important to the meaning.

6
Farmers in the surrounding countryside purchased human waste from the city.
→ Passive (keep by + agent)
7
The Shogunate enforced strict limits on consumer spending throughout the Edo period.
→ Passive (omit by + agent)
8
Scholars have debated whether the Edo model can be applied to modern cities.
→ Passive (present perfect)
9
Craftsmen repaired broken umbrellas, worn sandals, and damaged pottery rather than discarding them.
→ Passive (omit by + agent)
10
Many economists now consider the circular economy a viable alternative to growth-based models.
→ Passive using is considered
Set C — Hedging Language  ·  nuance, epistemic modality & academic caution

Rewrite each overconfident statement using the hedging expression given in brackets. You may need to restructure the sentence.

11
The Edo model proves that sustainability and prosperity are compatible.
→ Use could be argued that
12
Authoritarian control was responsible for Edo's environmental success.
→ Use seems to suggest
13
Modern cities cannot replicate the Edo circular economy.
→ Use might contend
14
Krznaric's analysis is too simplistic.
→ Use may well be
15
The isolation policy was the main reason for Edo's sustainability.
→ Use there is reason to believe

Stage 06

Speaking: Discussion & Debate

Discuss the following in pairs or small groups. Aim for 5–8 minutes per question. Challenge each other's assumptions and use the vocabulary from Stage 03.

Analysis Is the Edo economy truly a model for the future, or is it a romanticised version of a deeply unequal society? What are the risks of "green nostalgia"?
Application Which specific elements of the Edo circular economy — if any — could realistically be transplanted into your own city or country? What barriers would you face?
Evaluation Roman Krznaric is described as a philosopher. Does his framing of the Edo economy feel more philosophical than economic? Does his perspective strengthen or limit the argument?
Synthesis How does Japan's history of resource efficiency connect to its modern reputation for quality craftsmanship (monozukuri), minimalist aesthetics, and low food waste? Is this a cultural continuity or a coincidence?
Critical Thinking The video implies that consumption-driven economies cause environmental damage. Is this necessarily true? Can you think of counterarguments or exceptions?
Ethics How much individual freedom should people be expected to sacrifice for collective environmental benefit? Where do you draw the line?

Stage 07

Writing Task

Option A — Argumentative Essay (C2)

Write an argumentative essay of 350–450 words in response to the following statement:

"The circular economy of Japan's Edo period demonstrates that economic prosperity and environmental sustainability are not mutually exclusive — and that modern societies have much to learn from the past."

To what extent do you agree? Support your argument with evidence from the video and your own knowledge.

  • Use a clear thesis statement in your introduction
  • Present at least one counter-argument and refute it
  • Use hedging language and concessive clauses appropriately
  • Conclude with a nuanced, forward-looking reflection

Option B — Comparative Analysis (C1)

Write a 300–380 word comparative analysis responding to this prompt:

"Compare the waste management systems of Edo Japan and a modern European city of your choice. What does the comparison reveal about changing attitudes towards resources and sustainability?"

  • Use comparative structures: whereas, in contrast to, unlike, by comparison
  • Draw on specific examples from the video
  • Include your own research or general knowledge about the modern city
  • Avoid moralising — aim for balanced, analytical prose
Teacher's note — Assessment Criteria For C1–C2 assessment, evaluate: task achievement, range and accuracy of vocabulary and grammar, coherence and cohesion, appropriate register, and the quality of argumentation. Penalise overuse of direct quotation and reward original synthesis.
