Why we built Master Nihongo

Master Nihongo is a free, open-source study platform designed to help learners prepare for the Japanese-Language Proficiency Test (JLPT). Whether you're just discovering hiragana or pushing through N1 kanji, this site gives you the tools to study at your own pace — no account required, no paywall, no distractions.

What is the JLPT?

The JLPT (Japanese-Language Proficiency Test) is the most widely recognized Japanese language certification in the world. Held twice a year in over 90 countries, it tests reading comprehension, listening, vocabulary, and grammar across five levels — from N5 (beginner) to N1 (advanced). Passing the JLPT opens doors to Japanese universities, jobs in Japan, and career opportunities worldwide.
