NihongoShadow

Features
Read full description

NihongoShadow is a shadowing practice app for Japanese learners. Real Japanese teachers—not AI—personally correct your recordings so you can build natural pronunciation and intonation. WHY NIHONGOSHADOW • Corrections by native Japanese teachers Experienced teachers listen to every submission and give you specific, personalized feedback on your pronunciation habits and how to improve—advice tailored to your native language. • Human feedback, not AI Many services rely on automatic AI scoring. We insist on human corrections, so you receive feedback on the subtle nuances and intonation that AI simply cannot judge. • Exclusive original JLPT materials (N5–N1) Study with our own original materials for every JLPT level, developed in-house and optimized for shadowing. Build real skills with content you will not find anywhere else. • 24/7 chat with native teachers Ask about Japanese anytime—grammar, keigo, or “does this expression sound natural?” Casual conversation practice is welcome too. Learn real Japanese you will not find in textbooks. HOW IT WORKS 1. Choose a material suited to your level, from N5 to N1. 2. Listen to the native audio and record yourself shadowing. 3. Submit with a single tap. 4. Receive detailed corrections from native Japanese teachers within 24 hours.
