Learning Japanese comes down to a lot of repetition over a long period of time, at regular intervals. What else are you doing constantly every day that sounds the same? Entering passwords.
True, a lot of passwords can just be stored these days, not requiring you to type it in. But what if you ignored that and use every repetitive entry of your password to improve your Japanese memory?
A few password ideas
1. Your Facebook account?
2. Apple account?
3. Microsoft account?
4. Twitter account?
These are just a few examples, but if you make your password a Japanese sentence related to the account, you are creating a strong password (you can add a few extra characters at the end for more strength if you are worried) and giving yourself reason to expend all this extra energy. Every day you are typing out the same sentences.
You know how you are supposed to technically change your passwords frequently for better security? Use those password updates as a chance to learn a whole new set of sentences. Make them sentences you are having trouble remembering. There are a lot if possibilities here.
It’s like having Anki built into what you normally do anyway.
