I saw a similar post regarding a favorite means of something, so it gave me this idea as a topic to ask. What’s your favorite method or tool you use to help you speak or improve your conversational skills for Japanese?
I’ve been utilizing various YouTubers, such as Tomo sensei’s shadowing practice videos / playlist.
Besides talking to myself in my head while I’m trying to go to sleep, you mean?
I’m at a high N5/low N4 level (I think), and I’m working in a book that OMG Japan calls Beginner Japanese Sentence Training. It has interesting exercises. I worked through it for about the first 15 lessons, then got bogged down and went back to the beginning, and I’m finding it much easier the second time through. (It’s not the only thing I was doing during that time that helped me improve, though.) There are 90 lessons, so I have plenty to look forward to.
It’s not really conversation, of course, but it’s helping me work toward that. I find it just challenging enough. There’s an excellent answer booklet that offers a number of different options for how to say things. The first time through those 15 lessons, I had to look at the answer sheet to answer many of the questions, just to see how I might possibly word something (or what on earth they actually wanted). Even so, I found the exercises worthwhile. The second time through, I’m much better able to see how to express my ideas without help.
For listening, I’m mostly listening to YouTube videos for beginners.
Not very helpful but I just like talking so my answer is talking
There is a tachinomi place (small izakaya with no seating) I pass by sometimes and I started to get friendly with the regulars. If I have time (and if they are there) I like joining them outside for a few drinks and we speak Japanglish together. They’re mostly older men so they use fairly old fashioned English that they probably learned during the Showa period, and it’s kind of nice for me. Plus, they’re much more genki about it, probably because they’re drunk LMAO.
Since “drink with strangers in Japan” is not super viable advice for everyone though, other than that what I like the most is probably just imagining conversations in Japanese in my head. What I would want to say on a given topic etc. Sometimes I turn it into a written diary entry later.
Listening to Japanese music and reading along with the lyrics. Apple Music has time-synced lyrics for most songs; I assume other services do the same. The repetition in most songs makes it easier to start picking up the sounds, I think. I particularly like Babymetal and Nemophila, but I’m sure pretty much anything would work.
I’ve got so many random 名刺 in my wallet from a tachinomi wine bar I like doing this 
I should start doing a written diary to write about the many interesting characters I meet.
that sounds like a great theme for a diary exercise!! definitely do it!!
仲間！！！
can confirm that youtube music does the same! additionally i also like doing karaoke with japanese songs as well, which is mostly similar
Random question but do you have an ISBN for this book at all? Or a cover image?
I find exercises like those help me internalise grammar easier so I’m always on the hunt for more 
ISBN 978-4-89358-809-8 . I hope you like it as much as I do!
Awesome, thanks 
It’s now on my next CD Japan order along with several recent volumes of ongoing series 
Thanks for sharing the ISBN with us! I’m looking into it myself!
My favorite is joining a club in Japan.
If that’s not an option - do the pair work in Genki. (Or Minna no Nihongo)
