What You Can Do with KizunaCare

National Exam Preparation

We provide a national exam preparation feature designed to help international staff learn the knowledge required for the Certified Care Worker exam efficiently and easily.

Based on exam trends from the past 10 years, the curriculum is organized into 175 essential topics. Each topic follows a structured learning flow: ‘Video explanations in the student’s native language → Past exam practice → Summary of key points.’ With each topic designed to be completed in just 10 minutes, we make it possible for staff to study consistently and without strain while balancing their work responsibilities.

AI-Powered Communication Practice for Care Settings

Care Kaiwa AI” is a feature designed to help users practically master the Japanese language and specialized terminology needed in nursing care through AI-driven conversation.

Based on real-world caregiving scenarios, users can practice interactions with supervisors and residents. By learning specialized terms through simple explanations and examples, you move beyond just “understanding” to actually “using” Japanese. The AI automatically analyzes your speech to provide feedback for improvement, building the confidence you need to communicate effectively before you even step onto the floor.

JLPT Learning

Our JLPT Study Feature provides practical Japanese language training designed to help international staff work in Japan with confidence and long-term stability.

Covering levels N4 through N1, our mobile-friendly materials include vocabulary, grammar, reading comprehension, and past exam practice. We go beyond the standard curriculum by including expressions and vocabulary frequently used in nursing care, helping users acquire language skills directly applicable to their jobs. With a flexible design that makes it easy to study even in short bursts, we enable users to steadily improve their Japanese while balancing their daily work responsibilities.

Visualizing individual growth

CaregiverHub is a management dashboard that allows administrators to grasp the learning progress and growth of international care staff at a glance.

By visualizing study progress, comprehension levels, and test results in real-time, it enables data-driven coaching and follow-up support. We support a development environment that leads to long-term retention by ensuring that daily efforts and growth are accurately recognized and evaluated.
