Three fields are required. Everything else is optional and only exists to help us match you to studies you would actually enjoy. We do not sell this information, we do not add you to a marketing list, and you can ask us to delete it at any time.

Online questionnaire (20–40 min) Product sent to my home One-to-one video interview Group discussion In person, central London App or website usability session

How familiar are you with Japanese products? There is no right answer. For many studies "not at all" is exactly what the client needs.

Allergies or dietary restrictions Only used to exclude you from food and beauty studies that would be unsuitable. Full ingredient lists in English are always sent before you use anything.

Anything else

I agree to be contacted about relevant studies. I understand there is no fee, no obligation to accept any study, and that I can unsubscribe or request deletion at any time. Privacy notice. *

Also send me the journal — published panel findings and Japan writing, roughly monthly. Entirely separate from study invitations.

We usually confirm within two working days (UK hours). If you would rather not use a form, email hello@japanthebest.com with your country and age band.

If you are a Japanese company

This form is for research participants. If you want to commission product testing, group discussions or European market entry work, please use the Japanese-language enquiry form on our Japanese pages, or go directly to our sister practice Japan Business Insider.
