Hey :)

I am in a similar situation where, although there is a small Japanese community where I live, most of them would rather speak English to me anyway…

I have always had a huge interest in Japan/Japanese/culture since I lived in Japan as a young Air-Force brat, and see nothing wrong in learning a language just for the sake of it.

In fact, those who would tell you that you are wasting your time learning a language are crazy! It is so good for your brain, in addition to being super fun!

I am currently hammering my way through wani-kani and would highly recommend it since it is something you can do anywhere to learn (provided you have a smartphone) I am slowly making my way through textfugu for grammar, and have plans on learning, mostly, to read natively in Japanese.

If all goes well, I even plan on speaking in Japanese to my children (as my wife speaks to them in English).

In short, do what makes you happy :-)
