Nice progress! Never too late to start, and web dev is an exciting place in 2018.
Do you have a github I can follow? If you don't, MAKE ONE AND POST EVERYTHING THERE. Don't feel like your stuff isn't "good enough", just using git regularly shows other devs, and employers, that you are serious about programming.
Btw, are you located in Tokyo still? I've been involved in the tech scene here a while now, I can definitely introduce you to the right people if you want to start looking for an intern. I know you speak good Japanese so that shouldn't be a problem :)
