>>37254234Follow your (JP) oshi and her friends on twitter. Read the hiragana/katakana in every message, and in stream titles, it's a good way to retain kana in the early days. Once you start learning basic words you'll recognize some of the kanji as well like for streaming, waking or sleeping, feeling well or sick, singing, etc.
Finding ways to have those sorts of basic things saturating the stuff that you already usually interact with can help a lot, not with every word but with many of the foundational things. For example, if your oshi sings a lot, then the first time you learn the kanji and words for to sing/singer/etc., you won't forget them because you'll see it in all the streams, cover song descriptions, twitter, etc.
Basically exploiting the Baader-Meinhof effect (once you learn something you'll notice it everywhere it appears, which helps reinforce it much quicker).
