Our Story
Gramaru's journey started with a simple fascination: Japanese onomatopoeia. Words like どきどき (heart pounding), きらきら (glittering), and ごろごろ (rolling) captured our imagination with their ability to convey feeling and sound in ways English simply couldn't. But we quickly discovered that understanding these expressive words required mastering complex grammar patterns.
We spent years trying different learning methods but found that traditional approaches left grammar rules feeling abstract and disconnected from real usage. The breakthrough came when we started organizing grammar around meaningful patterns and contexts - beginning with those captivating onomatopoeic expressions that first sparked our interest.
Today, Gramaru has evolved from that initial onomatopoeia-focused approach into a comprehensive learning platform, but we've kept the same core philosophy: grammar should be learned through meaningful, contextual patterns that connect to how Japanese is actually used and experienced.
