How can I speak more fluently in Japanese?
I am learning Japanese, I'm getting pretty good so far at understanding some of it,
but the only problem, is that I'm a little bad at speaking fluently.
I heard that you can practice by actually speaking to another person In Japanese,
but that's not exactly an option at the moment. So, how else can I practice?
で答えは
If the only difficulty is finding another person, you can just speak to yourself in Japanese.
It might feel a bit silly, but it will help.
Some people also find it useful to record themselves, to get a better idea of what they actually sound like.
At the same time, input will also improve your fluency over time. So you should listen to as much Japanese as you can.
心の中でしゃべるだけでも効果があるようですよ。
