About Us

Survey Design Lab (SDL) is a Japan-based research and consulting firm specializing in public opinion research, social surveys, and market research.

Our team has extensive experience supporting international research projects conducted in Japan and has worked with leading research organizations and survey firms from around the world. We have successfully managed a wide range of studies, from public opinion and election surveys to academic and commercial research projects.

One of our key strengths is helping overseas organizations conduct research in Japan. We provide local expertise in survey design, sampling, fieldwork operations, and respondent recruitment while ensuring that global research standards are maintained.

Beyond translation, we specialize in questionnaire localization—adapting English and other foreign-language questionnaires into clear, natural Japanese that accurately reflects the original concepts while remaining culturally appropriate for Japanese respondents.

Combining international research experience with deep local knowledge, SDL serves as a trusted partner for organizations seeking to conduct high-quality research in Japan.
