Translating Surveys for Japanese Respondents: Wording, Rating Scales and Open Answers

By the Hanabuddies team · · 3 min read

To survey Japanese customers, employees or research participants, translate the questionnaire into natural, polite Japanese rather than literal Japanese, adapt the answer options to Japan, test it with a few native speakers, and plan how you’ll translate open-ended answers back. A literal translation can quietly change what a question asks, and Japanese respondents tend to answer differently from Western ones, especially on rating scales. Getting this right decides whether your data means anything. Here’s what to watch for.

Where literal translation goes wrong

  • Politeness. Questions written in plain or casual Japanese can feel rude. Surveys usually use polite です／ます forms and soft request phrases.
  • Direct questions. Blunt questions about dissatisfaction, income or complaints may get fewer honest answers. Wording can be softened without changing the meaning.
  • Double meanings. An English word may have several Japanese equivalents with different shades of meaning, such as “satisfied” or “recommend”. The translator has to choose the one that matches your intent.
  • Idioms and examples that make sense in your market but not in Japan.

Rating scales and Japanese respondents

Researchers often find that Japanese respondents choose the middle of a scale more and the extremes less than respondents in the US or Europe. That doesn’t mean they are less satisfied; it’s a difference in response style. Ways to deal with it:

  • Compare like with like. Compare Japanese results over time or against other Japanese results, rather than directly against another country.
  • Consider a scale without a middle point if you need people to lean one way.
  • Label every point clearly in Japanese, not just the ends.
  • Watch “recommend” questions. Scores on scales like “how likely are you to recommend us?” are often lower in Japan for the same level of loyalty.

Adapt the answer options

  • Location by prefecture or region of Japan, not states or counties.
  • Age in bands such as 20代 (twenties), which feels familiar.
  • Job and company type using categories common in Japan, such as company employee, civil servant, self-employed, part-time.
  • Income in yen ranges that make sense locally, if you ask at all.
  • Dates in Japanese format: 2026年10月16日.

Test before you launch

Ask three to five native speakers from your target group to complete the survey and say aloud what they think each question means. This catches confusing wording quickly. For high-stakes research, a back-translation, where a second translator turns the Japanese back into English, helps confirm that the meaning survived.

Translating the answers back

Open-ended answers are often the most valuable part, and they need translating back into English. Plan for it from the start: export the answers in a spreadsheet, keep a respondent ID next to each one, and ask for translations that keep the tone, because a polite complaint in Japanese can be more serious than it sounds. For deeper insight, follow up with interviews. See running customer interviews in Japanese.

Employee surveys

Engagement surveys for Japanese staff need extra care with anonymity. Make it clear in Japanese who sees the results and how they’re reported, or people may give safe, neutral answers. See also translating HR documents for Japanese staff.
