How to use Minna Mirror

Learn how to ask others, collect responses and read your results.

Create your own record

Start for free with Google or a passwordless email link. Use the same sign-in account on another device. Responses are accepted for one year from creation. Afterwards, new responses and self-answer edits close, while records remain viewable. Create a new record for the next year; full results cost ¥300 (tax included) per record, with no automatic renewal. Compare with purchased past records.

Ask people who know you

Share a public link with several people, or issue a separate invitation for each person. An invitation accepts the first response and does not verify identity. Respondents answer 16 questions for free, without an account. They can choose Not sure; at least two scored answers per axis are needed.

Read your results

Your basic type appears after three responses. The full results cost JPY 300 once per assessment, including later responses to that same assessment. A new assessment requires a separate purchase. There is no subscription. A valid coupon can also unlock full results.

Keep access to existing records

Enter a saved recovery code under Bring back your earlier records and verify with Google. For email sign-in, sign in first and then enter the code in Settings. A valid original browser session can also be transferred. If you forgot the code, sign in and request recovery in Settings using an answer link you sent. The operator must independently verify ownership before approval.

Choose what to share

Individual answers and respondent names are not displayed. Small groups and changes in aggregate values may still reveal clues. PDF exports and shared images reveal their displayed results to recipients. Never share your recovery code. This is an independent reflection tool, not the official MBTI assessment or a medical test.

Answer requirements and scoring

Answer at least two of the four questions per axis on the 1–5 scale. “Not sure” is excluded from the average. We average each respondent’s answers per axis, weight respondents equally, then convert to 0–100. An axis is X when the rounded whole-number score is 50%.

Percentages express responses on a 0–100 scale, not proportions of people, ability or diagnostic accuracy.

A public link collects responses; it does not publish your results. Anyone who receives a forwarded link can respond.
