Where can I find native Japanese people who are willing to practice speaking with me?

Some context first. Please bear with me.

On paper, I hold an N1 certificate, but due to lack of speaking practice in recent years, my confidence to speak has dwindled down to an embarassing level. The words just won’t come out. I can now only string simple words like a newbie.

I work in a Japanese company (not in Japan) and still use written Japanese daily but barely any speaking due to changes in my job desk. My overall Japanese skill is worse than it was 3 years ago.

I am inherently a quiet person so this just exacerbates things. I’m now looking to get out of this company and realized I need to brush up my speaking skill to get a better job.

So, back to the title. Do you guys know any platform or any way where I can get in touch with some native Japanese people or other Japanese language learners with similar level to practice speaking?

And on a broader scope, for non-native Japanese who are at this level of competency and not living in Japan, not exposed to the language 24/7, how do you guys maintain your Japanese language skill?

Thanks!
