For Foreign Nationals

The 17th Japanese National Fertility Survey is conducted by the National Institute of Population and Social Security Research, an affiliated organization of the Ministry of Health, Labour and Welfare. This survey covers foreign nationals residing in Japan. If you are a single man or woman aged 18-54, or a married woman aged 54 or younger, we kindly request your participation. For your reference, translations of the questionnaire are available below in the following languages： English, 中国語(繁體・简体),한국어, Português, Tiếng Việt, नेपाली.

• Why was my household selected for this survey?
• We ideally want to survey everyone, but that would be too expensive and require too many people. So, we survey a small number of households and use those answers to estimate the situation for everyone. Specifically, we randomly chose 1,000 areas from the areas used in the 2025 National Survey of Living Conditions. We are asking people who live in those areas to answer this survey. Your area was chosen as part of this process. As this is an important national survey that helps inform government policy, we sincerely request your cooperation.

• What date should I use when answering?
• Please provide information as of June 30, 2025.

• What if I'm unsure how to answer some questions?
• Please call our survey call center (the phone number shown at the bottom of this page) or ask the survey staff member who delivered your questionnaire.

• Is participation mandatory?
• While participation is voluntary, this survey is designed using statistical methodology to accurately understand marriage and childbirth trends across Japan. Your response helps ensure that government policies can effectively address real needs in our society. We greatly appreciate your cooperation in this important national research.
