I've been "learning Japanese" for like 20 years now, but from the US. During that time, I've heard a few times that it's possible to live in Japan in a "Gaijin bubble" where you deliberately surround yourself with other foreigners and remove the necessity to learn the local language.<p>After trying a <i>ton</i> of ways to learn, I think what was most effective was some kind of structured learning combined with <i>using the language</i> to consume content. For me, that was listening to anime (weak learning) and reading untranslated manga (much stronger) and even some really easy light novels. The structured content was necessary for the initial hurdle, but still provided more learning than the Japanese content, but the JP content provided stickiness for the structured learning.<p>They're both necessary.<p>If I lived in Japan, that "Japanese content" would have been just going out into the world and interacting with Japanese people, sticking to Japanese as much as possible.<p>I went there for a couple weeks once, and I didn't use my Japanese much, but what I did use still sticks with me to this day. Doing that more and more would be incredibly effective.<p>So if you want Anki to be your "structured content", that's probably fine. And that deck is probably a decent one. I have a feeling a pre-designed course (such as Duo Lingo or a Learn German book) would be better, but motivation and sticking to it is more important than anything.<p>You just need to pick something and stick to it, and <i>use it</i> in real life.
