[New Standard for Preventing Mismatch] Launch of New Feature Using MBTI to Prevent Early Breakups Caused by 'Personality Mismatch'

Background and Social Issues: Why Resolve 'Personality Mismatch' Now?

In recent years, 'mismatched values and personalities' have emerged as a major issue in Japan's divorce rates and the ways people meet through dating apps.

◎ 'Personality Mismatch' is the Top Reason for Divorce for Both Men and Women

According to 2024 judicial statistics, 'personality mismatch' was cited as the motive for filing for divorce mediation by 59.9% of men and 38.3% of women, making it the number one reason for both. This indicates that a failure to fully align deep values and personality compatibility before marriage leads directly to relationship breakdown. Furthermore, according to the Ministry of Health, Labour and Welfare's '2024 Population Dynamics Statistics (Confirmed),' the number of divorces in 2024 reached 185,904, with a divorce rate (per 1,000 population) of 1.55, an increase from the previous year. The ratio of divorces to 485,063 marriages (special divorce rate) reached approximately 38%, indicating that about one in three married couples divorces.

◎ Over Half of Dating App Users Crave 'Prior Value Alignment'

With the spread of dating apps, the number of encounters has increased dramatically. The domestic dating app market is projected to reach 109.4 billion yen in 2026 (a 7% increase from the previous year; Dating App White Paper 2026, November 2025). However, beneath the ease of meeting people, mismatches after dating are frequent. According to a survey by Omiai (part of Enito Group) in January 2026 (n=1,725), 53.3% of those who have experienced breaking up with someone they met on a dating app said, 'If I had asked about values and ways of thinking beforehand, the breakup could have been avoided.' Common regrets included 'views on love and marriage,' 'future image,' 'money sense,' and 'communication style,' all factors stemming from 'personality and value mismatches.' Basic profile information like photos and annual income does not convey one's 'true self,' leading to early breakups.

◎ 54% of Gen Z Use 'MBTI' as an Indicator for Human Relationships

As a means to avoid such 'mismatches,' 'MBTI diagnostics' are becoming established as a new protocol for building relationships, particularly among Gen Z. According to a survey by Yume-sta Inc. (October 2025), 54% of Gen Z respondents stated they use MBTI as an 'indicator for human relationships.' MBTI functions as a tool to reduce communication friction and psychological burden by understanding the partner's thinking processes and value tendencies in advance. Its use is spreading in social media self-introductions, job hunting, and romance, and the behavioral change of 'knowing compatibility before meeting' is particularly notable among young people.

New Discovery from In-house Research: Correlation between 'MBTI Compatibility' and 'Relationship Continuity Rate'

In an original survey conducted by the company (survey period: April 2025; subjects: 500 people with dating app experience; method: internet survey), a clear correlation was confirmed between MBTI type compatibility and relationship continuity rate.

• 53% of respondents said they did not know their partner's MBTI type beforehand. • Groups that matched after confirming MBTI compatibility had a 16-point lower early breakup rate (within 3 months) compared to groups that did not. • When matching between types considered 'highly compatible,' the relationship continuity rate was 13 points higher than the average.

This result aligns with the 'MBTI-based Matching Success Rate derived from 10,000 data points' announced by Hito-oshi in April 2025, showing that prior compatibility confirmation using MBTI is effective in preventing mismatches.

Overview of the New Feature: 'Yoitoki' MBTI Compatibility Diagnostic

Based on the above social background and survey results, Yoitoki is launching a new matching support feature on its dating test site that applies the MBTI framework.

This feature allows users to grasp the tendencies of a partner's values 'before meeting,' which is expected to suppress early breakups due to 'personality mismatch' that traditional condition-based searches could not prevent.

Future Outlook

Through the provision of this feature, Yoitoki aims to support the construction of long-term, stable partnerships beyond merely creating temporary encounters.
