Onomappu Hitoki is a native Japanese speaker with a passion for lifelong learning. In his journey to connect and support lifelong learners, Hitoki learned Japanese, Chinese, English, and Spanish. Professionally, he's a doctor who mastered the art of learning while studying the human brain. His YouTube channel Onomappu demonstrates this with fun videos so interesting, viewers forget they're learning! This same technique is showcased in Dirty Japanese, Second Edition, a fun read containing real Japanese not taught in schools or textbooks.
