How long does it take to learn Japanese?
If you’re an English speaker, Japanese is considered a very difficult language to learn.
The US Foreign Service Institute (FSI), which trains American diplomats and government employees, categorized Japanese as a Category III language in a paper called “Lessons learned from fifty years of theory and practice in government language teaching” (Jackson & Kaplan, 1999)—grouping it in the hardest of the three categories.
According to the FSI, adult learners with strong language-learning aptitude typically needed around 2,200 class hours (about 88 weeks of intensive study, including self-study and considerable time spent in-country) to reach Level 3 on the ILR scale in Japanese.
How long it takes to learn a language is a very difficult question to answer, so this is just an estimate.
