For both men and women, the volume zone is from early 30s to early 40s. A key feature is the large number of individuals with stable lifestyles who can be reliably introduced to each other.
As of January 2026
The volume zone for annual income for both men and women is 4 to 6 million yen. This aligns with general survey results regarding the income women seek in a marriage partner. The average annual income for private-sector employees announced by the National Tax Agency is 4.6 million yen (2024), making this a high-quality database for finding a marriage partner.
As of January 2026
A key feature is that over 70% of members have graduated from junior college, a four-year university, or graduate school. Since many members have stable, professional jobs, introductions can be made with confidence.
