Learn Japanese the fun and fast way

Whether you're studying Japanese for fun or preparing for a career in Japan, learning the language shouldn't feel like a chore. Studying through immersion is both the most fun and effective way to reach fluency.

You might have noticed that textbooks can only get you so far. And you might also have noticed that it's hard to find the right materials online for listening practice, since there's so much out there and much of it is overwhelmingly difficult. Mugi is here to help with:

A curated library of real videos matched to your level
Vocab & grammar drills that feel like a game instead of homework
A review algorithm that tells what to review and when
Instant explanations for tricky questions, words, and sentences

About Us

Alex and Mugi

Hi! I'm Alex, the developer of Mugi. I'm from the US and moved to Japan in 2015 through the JET Program. After that I joined Mercari, where I worked as a translator and later got into software. I'm now a solo developer and writer trying to help people learn Japanese and live fulfilling lives abroad.

Moving to Japan changed my life. It's a country with amazing opportunities for international residents, but language is still a barrier. I'm creating Mugi to help as many people as possible overcome that barrier, but in a more fun and sustainable way.

Say hi to Mugi! 🐾

This is Mugi, the real one! Aside from being Alex's boss, she's the inspiration for the app's name and mascot. She's been a loyal companion during long study sessions, late nights coding, and everything in between.
