Nurturing Growth Amidst Depopulation: The Success of ninaru Parenting Apps

In the face of Japan's declining birth rate, the ninaru app series, developed by Eversense Co., has witnessed remarkable growth, boasting its highest number of monthly active users in October 2025. The number of births in Japan reached an alarming low of 686,061 in 2024, according to the Ministry of Health, Labour and Welfare's demographic statistics, but the ninaru app has managed to grow its monthly active users by an impressive 103.9% compared to the previous year.

Stability in the Midst of a Declining Birth Rate

The first half of 2025 is projected to see births fall to about 319,079, a decrease of 3.3% from the previous year. This continuing decline has led to an increasingly challenging reality for couples considering parenthood. As the challenges of pregnancy, childbirth, and parenting mount, the demand for reliable information and supportive connections is growing stronger.

The ninaru series serves as a comprehensive parenting support app, catering to expectant mothers, fathers, and grandparents alike, propelling overall growth in its monthly active users.

Capturing Changes in Parenting Trends

The ninaru series has achieved this growth through three key initiatives:

1. A 98% Satisfaction Rate from the ninaru Online Classroom: The online sessions, offering guidance on childbirth preparation, childcare, educational financing, and career issues have proved invaluable, resonating well with families.

2. Expert-curated Reliable Information: The platform has strengthened its network of experts, including doctors, midwives, nutritionists, and financial planners, ensuring that users receive trustworthy advice tailored to their needs.

3. User-Centric Design and Operations: Eversense prioritizes incorporating user feedback to foster a trustworthy and enduring brand. This commitment has helped ninaru become a staple resource, facilitating family learning across generations.

The ninaru Online Classroom has seen participation soar to a cumulative total of 150,000 since its inception, with users rating their satisfaction at 98% in recent surveys. Compliments regarding its ability to educate users effectively while alleviating anxiety have built a reputation for the series as a credible learning platform.

Moreover, the initiative has fostered a culture of mutual learning on a community level, extending collaborations with enterprises, local governments, and healthcare professionals.

Future Aspirations

Looking forward, Eversense aims to expand collaborations with companies, municipalities, healthcare facilities, and educational institutions to create a platform where parenting households can access essential information and services seamlessly. They are keen to further enhance partnerships, including joint advertisements, co-hosted workshops, and integrated content strategies.
