PDF Translation Tool Comparison
Google Translate vs DeepL vs doc2lang
Source Document: IMF Annual Report 2025 Financial Statements (Page 36)
Translation Direction: English → Japanese
Analysis Date: February 2025
1. Analysis Overview
This report compares the Japanese translations of the IMF Annual Report 2025 Financial Statements (English original) produced by three translation tools — Google Translate, DeepL (free version), and doc2lang — based on actual screenshot results.
The analysis focuses on Note page 36, which covers:
- •Sensitivity analysis of defined benefit obligations (table)
- •Other assets and liabilities (two tables)
- •Borrowings description (Section 13)
2. Visual Overview: Full-Page Comparison
Let us start by looking at the overall appearance of each translation result.
Original (English)

Google Translate

DeepL (Free Version)

doc2lang

At first glance, doc2lang stays closest to the original layout, and DeepL also preserves the table structure well. Meanwhile, Google Translate inserts a watermark at the top of the page, and the DeepL free version adds a logo and promotional banner.
3. Page Header Section
Differences between the tools are already visible in the very first section of the page.
Google Translate

- •A "Machine Translated by Google" watermark is automatically inserted at the top of the page
- •The header is translated as "I. 一般部門" "2025年4月30日及び2024年4月30日終了会計年度の財務諸表注記"
DeepL (Free Version)

- •The DeepL logo and a promotional message encouraging users to upgrade to DeepL Pro are inserted at the top of the page
- •This is a limitation of the free version and is removed in the paid (Pro) plan
- •This ad insertion pushes the main content downward, reducing available page space
doc2lang

- •Translated as "I. 一般部門" "2025年および2024年4月30日終了事業年度の財務諸表に対する注記"
- •No extra insertions. Most faithful to the original layout
- •"Financial Years" is translated as "事業年度", which is appropriate for accounting documents (Google Translate's "会計年度" is also acceptable)
4. Sensitivity Analysis Table
This four-column table (assumption name, change range, increase impact, decrease impact) tests each tool's ability to handle tabular data.
Original

Google Translate

Issues found:
- Mistranslation in column header: The original "Assumption" is translated as "予測" (prediction) — a clear mistranslation; the correct term is "仮定" (assumption). Furthermore, the same word "assumption" is rendered as three different terms — "予測", "想定", and "仮定" — creating inconsistency within a single table
- Consistent notation: "0.5パーセント" (0.5 percent) is used uniformly across all rows (a positive point)
- "医療費の動向率": An acceptable translation of "Health care cost trend rate", though somewhat generic
- Table layout: Generally preserved; numerical relationships remain readable
DeepL

Issues found:
- Notable notation inconsistency: The most prominent issue is that the "Change in assumption" column mixes "0.5パーセント" and "0.5%" — the first row uses "0.5パーセント" while subsequent rows use "0.5%". This inconsistency within a single table is a significant issue for professional documents
- Mixed writing styles: The text immediately before the table ends with "〜は以下の通りです:" (polite style), while other sections use the formal "であった" style
doc2lang

Key features:
- Consistent notation with "0.5 パーセント": The same format is used throughout every row, maintaining uniformity
- Column headers: Consistently translated as "仮定" (assumption), "仮定の変更" (change in assumption), "仮定の増加" (increase in assumption), "仮定の減少" (decrease in assumption)
- "数理仮定": "Actuarial assumptions" is translated as "数理仮定" — a concise and accurate technical term in insurance and pension terminology
- "感度分析": Same expression as DeepL's "感度分析" — Google Translate also uses "感度分析"
5. Other Assets Table
Original

Google Translate

- •Table structure is well preserved
- •"基本料金未収金" / "未収追加料金": "Basic charges receivable" and "Surcharges receivable" are translated using "料金" (fees) — too generic for the IMF context where "charges" carries specific meaning
- •"投資取引およびその他の受取手形": "Receivables" is translated as "受取手形" (notes receivable), which is a different accounting concept; "未収金" (receivables) would be more appropriate
DeepL

- •Table structure is preserved. Styling changes (e.g., dotted borders) are present but the result remains readable
- •"基本料金未収入金" / "追加料金未収入金": "未収入金" is less standard than "未収金"
- •"投資取引及びその他の債権": "Receivables" is translated as "債権" — an appropriate accounting term
- •Unit notation: "(単位:百万SDR)" adds "単位:" (unit:) which is not in the original — a helpful clarification
doc2lang

- •Highest fidelity in table structure reproduction
- •"基本手数料未収金" / "追加手数料未収金": "Charges" is translated as "手数料" (commission/fees), which is closer to the financial context than "料金" (Google/DeepL) but slightly different from the official IMF term "賦課金". However, "手数料" is acceptable in general financial translation
- •"投資取引およびその他未収金": "未収金" (receivables) is the standard accounting term
- •Unit notation: "(SDR百万単位)"
6. Other Liabilities Table — Where Terminology Differences Are Most Pronounced
This table contains a concentration of IMF-specific terminology, making the differences between tools most apparent.
Original

Google Translate

| Original | Google Translate Output | Issue |
|---|---|---|
| Remuneration payable on members' reserve tranche position | Remuneration paid on 会員の準備金トランシェポジション | "会員" (members) — in IMF context, "加盟国" (member countries) is the correct term, as "members" refers to sovereign nations |
| Refundable commitment fees on active arrangements | Refundable commitment 料金 on アクティブな契約 | "アクティブな" is too literal — "有効な" (effective) is more appropriate. "契約" (contract) — the IMF standard term is "取極" (arrangements) |
DeepL

| Original | DeepL Output | Evaluation |
|---|---|---|
| Remuneration payable on members' reserve tranche position | Remuneration paid on 加盟国の準備枠ポジション | "加盟国" (member countries) is accurate. "準備枠" is an interpretive translation that works but is not the official IMF term |
| Refundable commitment fees on active arrangements | Refundable commitment fees on 有効な契約 | "有効な" (effective) is appropriate. "契約" (contract) — the IMF standard term is "取極" (arrangements) |
doc2lang

| Original | doc2lang Output | Evaluation |
|---|---|---|
| Remuneration payable on members' reserve tranche position | Remuneration paid on 加盟国のリザーブ・トランシュ・ポジション | Both "加盟国" and "リザーブ・トランシュ・ポジション" closely match IMF terminology. Note: IMF documents also use "トランシェ"; the variation between "トランシュ" and "トランシェ" stems from different Japanese transliterations of the French word "tranche" |
| Refundable commitment fees on active arrangements | Refundable コミットメント・フィー on 有効な取極 | "取極" is the official IMF translation of "arrangements" and doc2lang is the only tool among the three to use it. "コミットメント・フィー" is also a commonly used katakana expression in financial practice |
This is the key differentiator: Whether a tool translates "arrangements" as "取極" serves as a litmus test for IMF document translation expertise. Google Translate uses "契約" (contract), DeepL uses "契約" (and "取決め" in Section 13), while only doc2lang uses the correct "取極".
7. Section 13: Borrowings — Comprehensive Comparison of Style and Terminology
Original

Google Translate

- •Heading format collapse: "13.1 新規借入協定NAB は 40 の参加者による" — the heading "New Arrangements to Borrow" merges with the beginning of the body text, eliminating the distinction between heading and paragraph. This is a serious issue for practical use
- •Writing style: Uses polite "です/ます" form ("〜できます", "〜発効しました", "〜提供します"), which is somewhat informal for financial statement notes
- •Terminology: Uses "新規借入協定" and "信用協定" — the official IMF term is "取極"
- •"割当枠の財源": Translation of "quota resources". "クォータ資源" is more standard in IMF contexts
- •Punctuation issue: In the second paragraph, a new sentence begins immediately after a period without a space
DeepL

- •Clear headings: "13. 借入金" and "13.1 新たな借入取決め" are properly separated, with formatting close to the original
- •Highly natural Japanese: The sentence "GRAは、主にNABを主要な常設借入枠として、割当資源を一時的に補完するために借入を行うことができる" reads very fluently
- •Writing style: Consistent formal "である" style throughout ("〜できる", "〜がある", "〜であった")
- •Terminology: Uses "新たな借入取決め", which is close to but different from "取極". "執行理事会" is a literal translation of "Executive Board", but the official IMF Japanese term is "理事会"
- •Possible misreading of "全参加国": In the original, "all of which were effective" refers to arrangements, but DeepL appears to translate the subject as "all participating countries were effective" — potentially misidentifying the grammatical subject
doc2lang

- •Headings: "13. 借入" and "13.1 新規借入取極" — uses the correct IMF term "取極"
- •"クォータ資源": "Quota resources" translated as "クォータ資源". Using the katakana "クォータ" for "quota" is standard practice in IMF documents
- •"信用取極の集合": Accurately deconstructs and translates "standing set of credit arrangements"
- •"IMFクォータに対する第二の防衛線": Accurate IMF terminology
- •Writing style: Consistent formal "である" style throughout
- •Line break issue: An unnatural line break occurs after "貸付契約および手形購入契約(二国間)", splitting "借入協定)から構成される。" onto the next line. In the original this is a single sentence, but the break placement is awkward

13. Conclusion
Each of the three translation tools has distinct strengths, and the "best" tool depends on your specific use case.
Google Translate is free and instantly accessible, with significantly improved table structure preservation in recent years. While specialized terminology accuracy remains a challenge, it delivers sufficient quality for grasping the general content. It is the best choice for budget-constrained situations or casual information gathering.
DeepL produces the most fluent Japanese among the three tools and offers an excellent balance of quality and price. Despite some inconsistencies in notation, it is the most recommended tool for general business document translation. The paid version also eliminates ad insertions.
doc2lang handles specialized terminology unique to international organizations like the IMF — such as "取極", "クォータ", and "コミットメント・フィー" — with the highest accuracy, and surpasses the other two tools in layout fidelity and style consistency. It is the ideal choice for professional scenarios that demand formal, publication-ready translations.
Ultimately, the most practical approach is not to commit to a single tool, but to choose the right one based on your purpose, budget, and required quality level.
