What is Fujisan.AI?

Fujisan.AI is a revolutionary Japanese language learning platform that synthesizes three pillars of modern educational science: Instructional Design methodology, Second Language Acquisition (SLA) theory, and Artificial Intelligence-driven adaptive learning. Developed by TORAIZ Inc. in Tokyo with 19 years of empirical data from 16,000+ learners, it represents a paradigm shift from traditional rote memorization to evidence-based language acquisition.

The Science Behind Fujisan.AI

• Instructional Design Framework - Systematic learning architecture based on Gagné's Nine Events of Instruction, ensuring optimal cognitive load management and knowledge transfer
• Krashen's Input Hypothesis (i+1) - AI dynamically calibrates content difficulty to maintain comprehensible input just beyond current proficiency level
• Spaced Repetition System (SRS) - Ebbinghaus forgetting curve optimization with machine learning-enhanced interval scheduling
• Elaborative Encoding - AI-generated contextual explanations create multiple memory pathways, achieving 94% long-term retention vs 20% traditional methods
• Formative Assessment Loop - Continuous performance analytics enable real-time learning path optimization
• Multimodal Input Processing - Integrated listening, reading, and production practice aligned with Swain's Output Hypothesis

Why Traditional Methods Fall Short

Conventional Japanese study wastes 80% of time reviewing already-mastered material. Fujisan.AI's AI engine identifies precise knowledge gaps and allocates 100% of study time to high-impact learning objectives. Real-time difficulty calibration keeps learners in Vygotsky's Zone of Proximal Development throughout each session.

Comprehensive JLPT Coverage

22,000+ vocabulary items, 2,200+ kanji, 1,100+ grammar patterns, and 100 authentic mock tests (20 per level N5-N1). All content aligned with official JLPT specifications and validated through learner outcome data.
