Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Nihonzo – learn Japanese from the things you already love: videos, news and Japanese websites. Don't know a word? Tap it. Built for Vietnamese speakers, N5 to N1.
◆ LEARN FROM YOUR FAVOURITE VIDEOS
Add any Japanese video you love on YouTube – anime, vlogs, news, podcasts. Watch with subtitles and tap any word to look it up without leaving the video.
◆ READ REAL JAPANESE NEWS AT YOUR LEVEL
"Tin phù hợp" picks articles that match your vocabulary and suggests a few words and grammar points to learn before you read.
◆ BROWSE JAPANESE SITES & SOCIAL MEDIA, TAP TO LOOK UP
Open any Japanese site – NHK, Yahoo! Japan, blogs, social media – inside the app. Tap a word for its Vietnamese meaning, reading and Sino-Vietnamese reading.
◆ ASK AI ABOUT TRICKY PHRASES
Stuck on a sentence? Ask AI for an explanation in Vietnamese: grammar, nuance, similar examples. (Uses your own OpenAI, Google Gemini or DeepSeek API key – stored only on your device.)
◆ PRACTISE SPEAKING
Role-play 251 conversations: the app reads the other part, you say yours, and speech recognition scores how close you were. Plus casual spoken Japanese the way people really talk.
