Spaced-repetition learning schedules each review of a flash card just before your brain is likely to forget it, so easy items are shown less often while hard ones pop up sooner. Cognitive-psychology research going back to Ebbinghaus’s “forgetting curve” in the 1880s—and confirmed by dozens of modern MRI and classroom studies—shows that this timing strengthens the neural pathways that store long-term memories far more efficiently than massed “cramming” sessions. In short, smart intervals mean less total study time and dramatically better retention.
The Japanese–Language Proficiency Test (JLPT) is the global benchmark for non-native speakers of Japanese. Administered each July and December, it is split into five levels: N5 verifies survival basics; N4 checks elementary command of everyday topics; N3 marks the bridge to intermediate reading and listening; N2 certifies solid professional fluency in newspapers, TV, and most workplace conversations; and N1 signals near-native comprehension of advanced texts and nuanced speech. Universities, employers, and immigration authorities across Japan routinely use these scores to gauge language ability.
MeguKard is built to help users get to the N4 level by focusing on vocabulary. The app’s name honors my dearly beloved Megumi; it is my heartfelt wish that she, and everyone who studies with us, will find these cards a gentle, encouraging path to ever-stronger Japanese. --Weston Koyama
