Japanese economics vocabulary
経済学用語の日本語
What this method solves
Once 限界 maps to marginal, 逓減 to diminishing, and 余剰 to surplus, reading speed changes immediately.
How to use it
- 01
Organize core terms in three columns: Japanese, English, and your own language.
- 02
Prioritize the Japanese form of the 72 concepts in this index.
- 03
In practice, restate the model in Japanese rather than translating first.
While answering
In everyday Japanese 限界 means limit, but in economics it means marginal — this misreading derails the whole item.
vocabulary of increase and decrease
増減を表す語彙
What this method solves
増加, 減少, 上昇, 低下, 拡大, and 縮小 attach to different subjects, and mixing them reverses the direction.
How to use it
- 01
Circle the directional word in the sentence.
- 02
Confirm whether it refers to a price or a quantity.
- 03
Draw the corresponding movement as an arrow on the diagram.
While answering
Prices and rates take 上昇/低下 while quantities and income take 増加/減少 — a fixed pairing you can read by.
aligning with Japanese textbooks
日本語テキストとの対応
What this method solves
If you already studied economics at home, the shortest path is mapping what you know onto the Japanese textbook's chapter order, not relearning it.
How to use it
- 01
Map the twelve chapters here onto the textbook you already know.
- 02
Add only the Japanese names for models you already understand.
- 03
Reserve full study for the models that are genuinely new.
While answering
Japanese texts usually run micro then macro with IS-LM mid-macro; aligning the table of contents first saves considerable time.
